HTET PRT Mock Test - 9 - HTET MCQ

Teachers are very closely linked to their students and motivate them to increase their knowledge and to develop confidence in them.

National Literacy Mission was started by Indian government in 1988 to educate people of 15 - 35 age groups over an eighty-year period.

Teaching regularly and effectively in a class by teachers develops an interest in students in studies and it prevents them from being absent from school. The teacher must make sure that the study material used in the class is interesting for the students, and that she is able to clearly convey the idea. The involvement of students is also a must to develop interest in studies, and hence reduce absenteeism in the class.

The early life of a child from birth to the age of two years is called infancy. Parents play a very vital role in the growth and development of a child during this period.

In sports coaching, play and practice are said to be two of the key variables that influence skill acquisition. Hence, option 4 is the answer.

The question paper is for students so that teachers will get to know how much students have learned. Content coverage will assure the teacher that that question paper covers the complete chapter or not.
Hence, the correct answer is "Content coverage".

Constructivism is centered on the idea that human knowledge and learning are actively constructed by the learner, not passively received from the environment.

दिए गए विकल्पों में सही उत्तर विकल्प 3 ‘देशाटन’ है। अन्य विकल्प इसके अनुचित उत्तर हैं।

Key Points

• देशाटन का अर्थ होता है:- देश भ्रमण, पर्यटन करना।
• देशाटन का समास विग्रह:-
  • देश में अटन (भ्रमण)।
• अतः देशाटन शब्द तत्पुरुष समास का उदहारण है। क्योंकि यहाँ “का“ विभक्ति का लोप हुआ है। अतः सही उत्तर देशाटन होगा ।

अन्य विकल्प:-

Additional Information

• समास का तात्पर्य है ‘संक्षिप्तीकरण’। हिन्दी व्याकरण में समास का शाब्दिक अर्थ होता है छोटा रूप; जब दो या दो से अधिक शब्दों से मिलकर जो नया और छोटा शब्द बनता है उस शब्द को हिन्दी में समास कहते हैं।
• समास के उदाहरण:-
  • रसोई के लिए घर इसे हम रसोईघर भी कह सकते हैं।
  • राजा का पुत्र’ – राजपुत्र
• समास के निम्नलिखित छह भेद होते हैं—
• अव्ययीभाव समास - यदि एक शब्द की पुनरावृत्ति हो और दोनों शब्द मिलकर अव्यय की तरह प्रयोग हों वहाँ पर अव्ययीभाव समास होता है संस्कृत में उपसर्ग युक्त पद भी अव्ययीभाव समास ही मने जाते हैं।
• उदाहरण:-
  • प्रतिवर्ष =हर वर्ष
  • आजन्म = जन्म से लेकर
• तत्पुरुष समास - इस समास में दूसरा पद प्रधान होता है। यह कारक से जुदा समास होता है। इसमें ज्ञातव्य – विग्रह में जो कारक प्रकट होता है उसी कारक वाला वो समास होता है। इसे बनाने में दो पदों के बीच कारक चिन्हों का लोप हो जाता है उसे तत्पुरुष समास कहते हैं।
• उदाहरण:-
  • देश के लिए भक्ति = देशभक्ति
  • राजा का महल = राजमहल
• कर्मधारय समास - इस समास का उत्तर पद प्रधान होता है। इस समास में विशेषण -विशेष्य और उपमेय -उपमान से मिलकर बनते हैं उसे कर्मधारय समास कहते हैं।
• उदाहरण:-
  • पीताम्बर =पीत है जो अम्बर
  • महात्मा =महान है जो आत्मा
• द्विगु समास - द्विगु समास में पूर्वपद संख्यावाचक होता है और कभी-कभी उत्तरपद भी संख्यावाचक होता हुआ देखा जा सकता है। इस समास में प्रयुक्त संख्या किसी समूह को दर्शाती है किसी अर्थ को नहीं |इससे समूह और समाहार का बोध होता है। उसे द्विगु समास कहते हैं।
• उदाहरण:-
  • नवग्रह = नौ ग्रहों का समूह
  • दोपहर = दो पहरों का समाहार
• द्वन्द समास - इस समास में दोनों पद ही प्रधान होते हैं इसमें किसी भी पद का गौण नहीं होता है। ये दोनों पद एक-दूसरे पद के विलोम होते हैं लेकिन ये हमेशा नहीं होता है। इसका विग्रह करने पर और, अथवा, या, एवं का प्रयोग होता है उसे द्वंद्व समास कहते हैं।
• उदाहरण:-
  • जलवायु = जल और वायु
  • अपना-पराया = अपना या पराया
• बहुव्रीहि समास - इस समास में कोई भी पद प्रधान नहीं होता। जब दो पद मिलकर तीसरा पद बनाते हैं तब वह तीसरा पद प्रधान होता है। इसका विग्रह करने पर “वाला है, जो, जिसका, जिसकी, जिसके, वह” आदि आते हैं वह बहुब्रीहि समास कहलाता है।
• उदाहरण:-
  • गजानन = गज का आनन है जिसका (गणेश)

Hence, Option D is correct.

Convert all fractions to those with the same denominators and compare their numerators.
∴ The fraction greater than 7 / 8 is 11 / 12.

12 + 19 + 23 + 7 + x + 9 + 26 + 13 = 16 × 8
109 + x = 128
x = 128 – 109 = 19
Hence, Option D is correct.

Amount of flour left = 5.00 - 2.25 = 2.75.
Amount of sugar left = 3.50 - .75 = 2.75.

Area of square having sides 5 cm = 5² = 25 cm²

Area of smaller square having sides 1 cm = 1² = 1 cm²

Then area of 4 squares will be 4 cm²

Area of shaded portion will be =  Area of square having sides 5 cm - area of 4  smaller squares (Unshaded portion)

 Area of shaded portion = 25 cm² - 4 cm²

 Area of shaded portion = 21 cm²

Area of Trapezium Derivation Using a Parallelogram: 
To derive the formula for the area of a trapezium using parallelogram, we will consider two identical trapeziums, each with bases a and b and height h. Let A be the area of each trapezium. Assume that the second trapezium is turned upside down as shown in the figure below.

We can see that the new figure obtained by joining the two trapeziums is a parallelogram whose base is a + b and whose height is h. We know that

• the area of a parallelogram is base × height = (a + b) h.
• the area of the above parallelogram in terms of 'A' is, A + A = 2A.

Thus, 2A = (a + b) h

⇒ A = (a+b)h/2

Thus, the formula for the area of a trapezium is derived. where a and b are parallel sides and h is height.

Given three points (1,2),(3,−4)and(5,−6)

Let the coordinates o centre be O(h,k)

The distance from the centre to a point on the circumference is equal to radius.

∴ OA=OB=OC

From distance formula 

OA²=OB²

Use the distance formula to determine the distance between two points.

√{1-(-4)}² +{(-5)-7}²

=√25+144

=√169

=13

The correct answer is Option 3, i.e Hydrofluorocarbons.

• Hydrofluorocarbons (HFCs) has the highest global warming potential as compared to other gases. 
• Global Warming Potential (GWP) is used to measure the total energy that a particular gas absorbs over a particular period of time ( normally 100 years), compared to carbon dioxide. 
• Gases with a higher GWP absorb more energy, per pound, than gases with a lower GWP, and thus contribute more to warming Earth.
• The major atmospheric gases responsible for causing global warming are Carbon dioxide (CO2), Methane (CH4) and Nitrous Oxide.
• Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs) and Sulphur hexafluoride (SF6) are less prevalent GHGs but are very powerful.

Concept:

• Water is very important for human survival.
• Water in raw form contains various impurities such as harmful chemicals and microorganisms that cause disease.

Explanation:

• There are various ways to purify water.

Boiling

• Boiling is the traditional method used to purify the water.
• Various microorganisms have the capability to survive only at a favourable temperature.
• So when we boil the water, It kills almost all the pathogens present in it.
• So, it is also an effective method for purifying the water.

Filtering

• Filtration is the process used to separate unwanted particles from liquid or gases.
• It uses a filter medium through which the solution has to pass.
• The filter medium allows only the liquid to pass but not solid.
• Filtration can be of any kind biological, physical or mechanical.
• Filtration can help in purifying the water.

​Sterilizing

• Sterilization of the water is also an effective method to purify the water.
• It kills or eliminates all the microorganism that present in the water.
• It helps in preventing the water borne disease.

Thus, boiling, filtering and sterilizing all are the method to purify the water.

Additional Information

Other methods used to purify the water are as follows:

Purification by chlorine tablets:

• Chlorination ​is the process of adding chlorine to the water to kill pathogens or disinfect the water.
• It is an effective method of water purification.
• Chlorine kills a large variety of microorganisms.

Coagulation:

• ​The process of adding alum to the water to disinfect the water is called coagulation.
• Alum acts as an electrolyte present in the water that attracts all the unwanted particles present in the water.
• This helps in settling down the suspended particles in the water.
• So, it is also an effective method for purifying the water.

The correct answer is Its momentum is doubled.

Key Points

• Momentum is a vector quantity; it has both magnitude and direction.
• Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
• Momentum can be calculated by multiplying the mass of an object by its forward velocity. (mv = kg*m/s).
• Mass and velocity are both directly proportional to the Momentum.
  • If you increase either mass or velocity, the Momentum of the object increases proportionally.
  • If you double the mass or velocity, you double the Momentum.
  • If you halve the mass or velocity, you half the Momentum.
• Newton's laws of motion-
  • ​Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by force. This postulate is known as the law of inertia.
  • Newton’s second law is a quantitative description of the changes that a force can produce in a body's motion. It states that the time rate of change of a body's momentum is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity.
  • Newton’s third law states that when two bodies interact, they apply forces to one another equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. This law is important in analyzing static equilibrium problems, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion.

Important Points

• Acceleration, the rate at which velocity changes with time in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant because the direction is continually changing.
• Kinetic energy, a form of energy that an object or a particle has because of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and gains kinetic energy. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
• Potential energy, stored energy that depends upon the relative position of various parts of a system. Spring has more potential energy when it is compressed than stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
