Scientists recently discovered that Emperor Penguins—one of Antarctica’s most celebrated species—employ a particularly unusual technique for surviving the daily chill. As detailed in an article published today in the journal Biology Letters, the birds minimize heat loss by keeping the outer surface of their plumage below the temperature of the surrounding air. At the same time, the penguins’ thick plumage insulates their body and keeps it toasty. . . .The researchers analyzed thermographic images . . . taken over roughly a month during June 2008. During that period, the average air temperature was 0.32 degrees Fahrenheit. At the same time, the majority of the plumage covering the penguins’ bodies was even colder: the surface of their warmest body part, their feet, was an average 1.76 degrees Fahrenheit, but the plumage on their heads, chests and backs were -1.84, -7.24 and -9.76 degrees Fahrenheit respectively. Overall, nearly the entire outer surface of the penguins’ bodies was below freezing at all times, except for their eyes and beaks. The scientists also used a computer simulation to determine how much heat was lost or gained from each part of the body - and discovered that by keeping their outer surface below air temperature, the birds might paradoxically be able to draw very slight amounts of heat from the air around them. The key to their trick is the difference between two different types of heat transfer: radiation and convection.The penguins do lose internal body heat to the surrounding air through thermal radiation, just as our bodies do on a cold day. Because their bodies (but not surface plumage) are warmer than the surrounding air, heat gradually radiates outward over time, moving from a warmer material to a colder one. To maintain body temperature while losing heat, penguins, like all warm-blooded animals, rely on the metabolism of food. The penguins, though, have an additional strategy. Since their outer plumage is even colder than the air, the simulation showed that they might gain back a little of this heat through thermal convection—the transfer of heat via the movement of a fluid (in this case, the air). As the cold Antarctic air cycles around their bodies, slightly warmer air comes into contact with the plumage and donates minute amounts of heat back to the penguins, then cycles away at a slightly colder temperature.Most of this heat, the researchers note, probably doesn’t make it all the way through the plumage and back to the penguins’ bodies, but it could make a slight difference. At the very least, the method by which a penguin’s plumage wicks heat from the bitterly cold air that surrounds it helps to cancel out some of the heat that’s radiating from its interior. And given the Emperors’ unusually demanding breeding cycle, every bit of warmth counts. . . . Since [penguins trek as far as 75 miles to the coast to breed and male penguins] don’t eat anything during [the incubation period of 64 days], conserving calories by giving up as little heat as possible is absolutely crucial.Q.

Q. Which of the following can be responsible for Emperor Penguins losing body heat?
Ruchika Chandi answered • 27 minutes agoOption A: It has been mentioned that food metabolism is used to maintain body temperature. But it cannot be inferred that heat is lost due to food metabolism.
Option B: The colder temperature of plumage results in slight heat gain from the surrounding air. Hence this option is incorrect.
Option C: In the last paragraph of the passage, it has been mentioned that heat is very important for the breeding of Emperor Penguins.
So it can be inferred that this conserved heat might be used in the reproductive process of Emperor Penguins. Hence C is the answer.
Option D: Consider the line: "Since their outer plumage is..........................thermal convection—the transfer of heat via the movement of a fluid (in this case, the air)." It is clear that the process of thermal convection is responsible for heat gain and not heat loss. Hence D is incorrect.

Nipun Tuteja answered • 13 hours agoThere are seven vehicles of three types and three owners. No two types of vehicles are same in number and no two among the owners have the same number of vehicles. Hence the number of vehicles of each type is 4, 2 and 1 and the number of vehicles with each of them is 4, 2 and 1 in any order.
As, no two vehicles owned by the same person are adjacent to each other, the vehicles of the person who own four vehicles will be at the first, third, fifth and seventh positions. As, the vehicle owned by Nitika is at one end, Nitika owned four vehicles.

DIRECTIONS for the question: Read the passage and answer the question based on it.Consider these recent headlines: “Want to be Happier? Be More Grateful,” “The Formula for Happiness: Gratitude Plays a Part,” “Teaching Gratitude, Bringing Happiness to Children,” and my personal favorite “Key to Happiness is Gratitude, and Men May be Locked Out.”Buoyed by research findings from the field of positive psychology, the happiness industry is alive and flourishing in America. Each of these headlines includes the explicit assumption that gratitude should be part of any 12-step, 30-day, or 10-key program to develop happiness. But how does this bear on the question toward which this essay is directed? Is gratitude queen of the virtues? In modern times gratitude has become untethered from its moral moorings and collectively, we are worse off because of this. When the Roman philosopher Cicero stated that gratitude was the queen of the virtues, he most assuredly did not mean that gratitude was merely a stepping-stone toward personal happiness. Gratitude is a morally complex disposition, and reducing this virtue to a technique or strategy to improve one’s mood is to do it an injustice.Even restricting gratitude to an inner feeling is insufficient. In the history of ideas, gratitude is considered an action (returning a favor) that is not only virtuous in and of itself, but valuable to society. To reciprocate is the right thing to do. “There is no duty more indispensable that that of returning a kindness” wrote Cicero in a book whose title translates “On Duties.” Cicero’s contemporary, Seneca, maintained that “He who receives a benefit with gratitude repays the first installment on his debt.” Neither believed that the emotion felt in a person returning a favor was particularly crucial. Conversely, across time, ingratitude has been treated as a serious vice, a greater vice than gratitude is a virtue. Ingratitude is the “essence of vileness,” wrote the great German philosopher Immanuel Kant while David Hume opined that ingratitude is “the most horrible and unnatural crime that a person is capable of committing.”Gratitude does matter for happiness. As someone who for the past decade has contributed to the scientific literature on gratitude and well-being, I would certainly grant that. The tools and techniques of modern science have been brought to bear on understanding the nature of gratitude and why it is important for human flourishing more generally. From childhood to old age, accumulating evidence documents the wide array of psychological, physical, and relational benefits associated with gratitude. Yet I have come to the realization that by taking a “gratitude lite” approach we have cheapened gratitude. Gratitude is important not only because it helps people feel good, but also because it inspires them to do good. Gratitude heals, energizes, and transforms lives in a myriad of ways consistent with the notion that virtue is both its own reward and produces other rewards.To give a flavor of these research findings, dispositional gratitude has been found to be positively associated qualities such as empathy, forgiveness, and the willingness to help others. For example, people who rated themselves as having a grateful disposition perceived themselves as having more prosocial characteristics, expressed by their empathetic behavior, and emotional support for friends within the last month. When people report feeling grateful, thankful, and appreciative in studies of daily experience, they also feel more loving, forgiving, joyful, and enthusiastic. Notably, the family, friends, partners and others that surround them consistently report that people who practice gratitude are viewed as more helpful, more outgoing, more optimistic, and more trustworthy.

Mn M Wonder Series answered • 13 hours agoThe total number of customers surveyed for Saturday night is 75 + 64 + 45 + 43 + 40 + 17 = 284. The number of customers willing to wait at least 25 minutes on Saturday night is 64 + 45 + 43 + 40 + 17 = 209.
The required probability is 209/284 = 0.7359.

Ruchika Chandi answered • 13 hours agoLet f(x) = ax2 + bx + c
► F(2) = 10 → 4a + 2b + c = 10
► F(0) = 4 → c = 4.
will be 0, 2ax + b = 0 → 4a + b = 0
► F(2) = 10 → 4a + 2b + c = 10
► F(0) = 4 → c = 4.
will be 0, 2ax + b = 0 → 4a + b = 0
Solving these we get
► a = -1.5
► b = 6
► c = 4.
So, f(x) = -1.5x2 + 6x + 4
at x = 5 gives -3.5.
► a = -1.5
► b = 6
► c = 4.
So, f(x) = -1.5x2 + 6x + 4

DIRECTIONS for the question: Read the passage and answer the question based on it.Workhouses have long assumed a central place in studies on the poor laws. While we know that the majority of relief claimants were actually given outdoor relief in money or in kind from the parish pay-table, welfare historians have shown that many individuals entered workhouses during moments of both short and long-term need. This dynamic has a long history. The Elizabethan poor laws permitted parishes to find accommodation for ‘poor impotent people’ in addition to the requirement to ‘set to work’ their poor. Some cities had obtained their own ‘Local Acts’ which contained specific legislation designed for the specific welfare needs of that locale. Central to these Acts was the workhouse. The first Local Act was passed in 1696 for the Civic Incorporation of Bristol.Born in Staffordshire, Gilbert was a chief land agent to Lord Gower and a keen poor law reformer. Through his work, he developed an immense political, legal, commercial and industrial knowledge which enabled the Gower estate to become one of the most prosperous in England. Gilbert’s concern for the poor may have stemmed out of his role as agent, which had allowed him to take onboard the role of paymaster for a charity of naval officers’ widows. As Marshall noted, Gilbert thought old parish workhouses were ‘dens of horror’. Such workhouses were too uncomfortable for those who were in poverty due to no fault of their own and places where the young were susceptible to ‘Habits of Virtue and Vice’ learnt from ‘bad characters’. For the sake of both the poor and the rates, Gilbert thought that workhouses should be reformed to promote industrious behavior.These ideas culminated in a new bill and the subsequent Act of 1782 which enabled parishes to provide a workhouse solely for the accommodation of the vulnerable. Although such residents were, as Gilbert put it, ‘not able to maintain themselves by their Labor’ outside of the workhouse they were still to ‘be employed in doing as much Work as they can’ within the workhouse. Work was therefore a part of everyday life within a Gilbert’s Act workhouse. The able-bodied were only to be offered temporary shelter and instead were to be found employment and provided with outdoor relief. Those who refused such work (the ‘idle’) were to endure ‘hard Labor in the Houses of Correction’.How was such a workhouse to be established and managed? Gilbert wanted to allow parishes to unite together so that they could combine their resources and provide a well built and maintained workhouse. According to Steve King, Gilbert’s Act was the first real breach of the Old Poor Law principle ‘local problem - local treatment’. Yet, any ‘Parish, Town, or Township’ was also permitted to implement the law alone, and hence concerns over poverty did not always transcend parish boundaries. Gilbert’s Act workhouses were to be managed in a different way compared to the older parish workhouses. Gilbert believed that the poor laws had been ‘unhappily’ executed ‘through the misconduct of overseers’. Such officers, he claimed ‘gratify themselves and their Favorites, and to neglect the more deserving Objects’.

Imk Pathshala answered • yesterdayLet the fares charged by Indian, Jet and Deccan be 6x, 9x and 4x respectively. Total trips = 400
Therefore collection/trip = 1600 lakhs / 400 = 4lakhs Total number of passengers = 100 fare in Deccan = 4lakhs/100 = Rs. 4000 Therefore 4x = 4000 => x = 1000. The fares of Indian and Jet after the rise will be 7.2x and 9.9x respectively. Since the total journey time is 6hrs, the only possibility is one trip by Deccan and two trips by " Indian. Thus the total fare will be 4000 + 2 × 7200 = Rs. 18,400.

Aadhar Academy answered • yesterdayf(x – 2) + f(x + 2) = f(x).
f(0) + f(4) = f(2) and f(2) + f(6) = f(4)
⇒ f(2) + f(6) = f(2) – f(0) i.e. f(0) = -f(6).
f(0) + f(4) = f(2) and f(2) + f(6) = f(4)
⇒ f(2) + f(6) = f(2) – f(0) i.e. f(0) = -f(6).
So, f(x) = -f(x + 6). f(1) = -f(7) and so on.
f(1) + f(2) + f(3) + … + f(11) = f(6) = -f(0) = -4.
f(1) + f(2) + f(3) + … + f(11) = f(6) = -f(0) = -4.

DIRECTIONS for the question: Read the passage and answer the question based on it. My new mistress proved to be all she appeared when I first met her at the door- a woman of the kindest heart and feelings. She had never had a slave under her control previously and prior to her marriage she had been dependent upon her own industry for a living. She was by trade a weaver, and by constant application to her business, she had been in a good degree preserved from the lighting and dehumanizing effects of slavery. I was utterly astonished at her goodness. I scarcely knew how to behave towards her. My early instruction was all out of place. The crouching servility, usually so acceptable a quality in a slave, did not answer when manifested toward her. Her favor was not gained by it; she seemed to be disturbed by it. She did not deem it to be impudent or unmannerly for a slave to look in the face. The meanest slave was put fully at ease in her presence, and none left without feeling better for having seen her. But alas! This kind heart had but a short time to remain such. The fatal poison of irresponsible power was already in her hands, and soon commenced its internal work.Very soon I went to live with Mr. and Mrs. Auld; she very kindly commenced to teach me the A, B, C. After I had learnt this, she assisted me in learning to spell words of three and four letters. Just at this point of my progress, Mr. Auld found out what was going on , and at once forbade Mrs. Auld to instruct me further, telling her that it was unlawful, as well as unsafe, to teach a slave to read. Further he said, "If you give a slave an inch, he will take a mile. A slave should know nothing but to obey his master - to do as he is told to do. Learning would spoil the best slave in this world.

DIRECTIONS for the question: Read the passage and answer the question based on it.
My new mistress proved to be all she appeared when I first met her at the door- a woman of the kindest heart and feelings. She had never had a slave under her control previously and prior to her marriage she had been dependent upon her own industry for a living. She was by trade a weaver, and by constant application to her business, she had been in a good degree preserved from the lighting and dehumanizing effects of slavery. I was utterly astonished at her goodness. I scarcely knew how to behave towards her. My early instruction was all out of place. The crouching servility, usually so acceptable a quality in a slave, did not answer when manifested toward her. Her favor was not gained by it; she seemed to be disturbed by it. She did not deem it to be impudent or unmannerly for a slave to look in the face. The meanest slave was put fully at ease in her presence, and none left without feeling better for having seen her. But alas! This kind heart had but a short time to remain such. The fatal poison of irresponsible power was already in her hands, and soon commenced its internal work.
Very soon I went to live with Mr. and Mrs. Auld; she very kindly commenced to teach me the A, B, C. After I had learnt this, she assisted me in learning to spell words of three and four letters. Just at this point of my progress, Mr. Auld found out what was going on , and at once forbade Mrs. Auld to instruct me further, telling her that it was unlawful, as well as unsafe, to teach a slave to read. Further he said, "If you give a slave an inch, he will take a mile. A slave should know nothing but to obey his master - to do as he is told to do. Learning would spoil the best slave in this world. "Now," said he, "If you teach that boy (speaking of myself) how to read, there would be no keeping him. It would forever unfit him to be a slave. He would at once become unmanageable, and of no value to his master. As to him, it could do him no good, but a great deal of harm. It would make him discontented and unhappy.

Mn M Wonder Series answered • yesterday►Refer second para: ‘Mr. Auld found out what was going on , and at once forbade Mrs. Auld to instruct me further, telling her that it was unlawful, as well as unsafe, to teach a slave to read.’
►The author states that Mr. Auld wants his wife to stop teaching him because Mr. Auld feels that if a slave learns to read then he is of no use to his master. Also that the slave will not be manageable any longer and that the slave himself will not be happy. Both A and C are correct.

Harsh Raj asked • 5 hours agoThe passage given below is followed by four summaries. Choose the option that best captures the author ’s position.
For each of the past three years, temperatures have hit peaks not seen since the birth of meteorology, and probably not for more than 110,000 years. The amount of carbon dioxide in the air is at its highest level in 4 million years. This does not cause storms like Harvey- there have always been storms and hurricanes along the Gulf of Mexico- but it makes them wetter and more powerful. As the seas warm, they evaporate more easily and provide energy to storm fronts. As the air above them warms, it holds more water vapour. For every half a degree Celsius in warming, there is about a 3% increases in atmospheric moisture content. Scientists call this the Clausius-Clapeyron equation. This means the skies fill more quickly and have more to dump. The storm surge was greater because sea levels have risen 20 cm as a result of more than 100 years of humanstorm surge was greater because sea levels have risen 20 cm as a result of more than 100 years of human–related global warming which has melted glaciers and thermally expanded the volume of seawater.(2017)... more

Divya Wilson asked • 20 hours agoEight friends: Ajit, Byomkesh, Gargi, Jayanta, Kikira, Mamk, Prodosh and Tapesh are going to Delhi from Kolkata by a flight operated Py Cheap Air. In the flight, sitting is arranged in 30 rows, numbered 1 to 30, each consisting of 6 seats, marked by letters A to F from left to right, respectively. Seats A to C are to the left of the aisle (the passage running from the front of the aircraft to the back), and seats D to F are to the right of the aisle. Seats A and F are by the windows and referred to as Window seats, C and D are by the aisle and are referred to as Aisle seats while B and E are referred to as Middle seats. Seats marked by consecutive letters are called consecutive seats (or seats next to each other). A seat number is a combination of the row number, followed by the letter indicating the position in the row; e.g., 1A is the left window seat in the first row, while 12E is the right middle seat in the 12th row.Cheap Air charges Rs. 1000 extra for any seats in Rows 1, 12 and 13 as those have extra legroom. For Rows 210, it charges Rs. 300 extra for Window seats and Rs. 300 extra for Aisle seats. For Rows 11 and 14 to 20, it charges Rs. 200 extra for Window seats and Rs. 400 extra for Aisle seats. All other seats are available at no extra charge.The following are known: - The eight friends were seated in six different rows.
- They occupied 3 Window seats, 4 Aisle seats and 1 Middle seat.
- Seven of them had to pay extra amounts, totaling to Rs. 4600, for their choices of seat. One of them did not pay any additional amount for his/her choice of seat.
- Jayanta, Ajit and Byomkesh were sitting in seats marked by the same letter, in consecutive rows in increasing order of row numbers; but all of them paid different amounts for their choices of seat. One of these amounts may be zero.
- Gargi was sitting next to Kikira, and Mamk was sitting next to Jayanta.
- Prodosh and Tapesh were sitting in seats marked by the same letter, in consecutive rows in increasing order of row numbers; but they paid different amounts for their choices of seat. One of these amounts may be zero.
