According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
So lightest in weight is C.

Let CP of the article be Rs. 100

⇒ SP of the article = 100 × 180/100 = Rs. 180

New cost price = 100 × 120/100 = Rs. 120

⇒ New profit = 180 – 120 = 60

Profit percentage = 60/120 × 100 = 50%

The pattern followed here is:

The positional value of the letter is given as their code.

Given code:

PASS → 1611919

Similarly,

Thus ASAP → 119116

Hence, the correct answer is "119116".

So A is the heaviest in the weight.

Hence, the person will be allowed to write a written test.

Hence, the above image is the correct answer.

Among the given options, only jpeg and gif are graphics formats. Jpeg format supports lots of colors and it also compresses static images better than gif.

Office Open XML (OOXML) format was introduced with Microsoft Office 2007 and became the default format of Microsoft Word ever since. Pertaining file extensions include: . docx – Word document.

Animals solve problems by understanding – like human beings, instead of going through either the trial and error process or stimulus response association. In this case, learning took place by insight. Learning by insight involves finding a solution to the problem by thinking over the problem and understanding the various aspects of the problematic situation.
Insight learning refers to the sudden realisation of the solution of any problem without repeated trials or continuous practices. To further elaborate on its definition, insight learning is the type of learning in which one draws on previous experience and also seems to involve a new way of perceiving logical and cause-and-effect relationship.

It is based on personal choice of a teacher whether to take interest in politics or not. He/she is not expected to do so.

She should keep her pace of teaching slow, while paying extra attention towards the weaker students. It will be beneficial to both weak and intelligent students, and will not cause lack of interest in bright students too.

Given peak potential is 200v
so, amplitude is 200
and frequency is 50Hz
so angular frequency is 2.πx50 = 314/sec
so the value is
E = 200sin(314t)
Hence option B is the correct answer.

Coulombs law states the force between two charged particles is directly proportional to the product of charges and inversely proportional to the square of distance between them.
So if the distance is doubled then the force would decrease 4 times.
So the new force would be 120/4=30 Newton.

When we use white light, the central bright will have light from all wavelengths as none of them cancel out. Hence the central bright fringe appears white.
For other bright fringes, depending on the wavelength of light constructive interference will not take place for certain wavelengths. Hence they will not be white, rather will be coloured, hence differentiated from central fringe.

Fringe width is inversely proportional to the distance between slits so it will be doubled.

For sustainable interference wavelengths have to be the same. So frequency has to be the same too. Contact phase relation is also necessary to sustain the interference pattern else the pattern will keep changing so rapidly that we will not see any pattern.
Equal intensity is not a requirement to keep pattern sustained.

When we connect cells to form a battery, we join opposite ends(+ve with -ve and vice versa) to get supporting emf, i.e. net emf get added, but when we join the same polarities(-ve with -ve, like in the question), they oppose each other, hence net emf is the difference b/w them.
The expression for equivalent emf when two cells of emf’s
ε_eq = ε₁ - ε₂ (ε₁> ε₂)

Horizontal component is a component of Earth’s magnetic field along the horizontal direction in the magnetic meridian. It is denoted by B_H. If B is the intensity of Earth’s total magnetic field, then the horizontal component of Earth’s magnetic field is given by:
B_H=Bcosδ

The situation is shown in the figure.
F_E= Force due to electric field F_B = Force due to magnetic field It is given that the charged particle remains moving along X-axis (i.e. undeviated). Therefore  F_B = F_E

When the volume of a soap bubble increases 27 times, its radius increases from r to 3r (since volume is proportional to the cube of the radius).

The work done in increasing the surface area for a soap bubble (which has two surfaces) is W = 2 × surface tension × increase in surface area.

The increase in surface area is 4π(3r)² - 4πr² = 4π(9r² - r²) = 32πr².

Therefore, the work done is 2 × T × 32πr² = 64πr²T.

We know, the gravitational force  
 

This is valid when R is the centre to centre distance between the two masses M and m.

At a distance r < R, the mass of Earth cannot be taken as M.

The new mass (M'):

The mass of earth will be contained for a radius r. Let us assume that the mean density of the earth is ρ and that earth is a sphere with a radius equal to the distance r. We know, mass = density × volume

Therefore the gravitational force, 

Hence the gravitational force, F ∝ r

 Mass of Gold pieces = 2 × 0.035 = 0.070 g
 Mass of box = 2.3 g
 Total mass of box with gold pieces = 0.070 + 2.3 = 2.370 g

Since the answer should be in 2 significant digits, therefore, on rounding off, we get 2.4 g.

Thus, the required answer will be 2.4 g.

Electric force F=qE
given, F=3000N,q=3C
∴E=F/q​=3000/3​=1000 V/m
Potential difference, V=Ed where d=0.01m
∴V=1000×0.01=10V

'Dyslexia' is a term known for reading disorder. The person having this disorder faces difficulty in learning to read or interpret words, letters, and other symbols, but it is not related to general intelligence. It will not have any impact on a person's general intelligence. It is a hereditary disorder that mostly runs in families. Hence, the correct answer is, 'Reading disorder.'

Individual differences refer to how individuals differ from each other. Different people have different interests; and their behavior is influenced by these interests, likings, dislikings, values, beliefs, etc. 
For example, you may like dancing and gossiping with friends, but your friend may not like these

Useful strategies for teaching students with mental retardation include the following:

• Teach one concept or activity component at a time
• Teach one step at a time to help support memorisation and sequencing
• Teach students in small groups, or one-on-one if possible
• Always provide multiple opportunities to practice skills in a number of different settings
• Use physical and verbal prompting to guide correct responses, and provide specific verbal praise to reinforce these responses

If the final rays are converging, we have a real image.
This is because a real image is formed by converging reflected/refracted rays from a mirror/lens.
The correct answer is option B.
