Figure 1 shows three water bottles P, Q and R attached to Shriram’s bicycle. The dotted line indicates the level of water in half filled bottle Q when the bicycle was parked on a flat ground. Shriram took the bicycle for a ride, at that time all the three bottles were half filled with water. Which of the following shows the likely level of water in all the bicycle is going DOWN a slop?

During the Apollo moon walk, Commander Scott performed the following demonstration. He held out a hammer and a feather and released them simultaneously from approximately the same height. Both took the same time to reach the surface of the Moon. Which of the following could be the reason for this?
- A.
  
  The Moon has a curved surface
- B.
  
  Things do not have weight on the moon
- C.
  
  There is no air on the moon
- D.
  
  There is no gravity in space
Correct Answer
C. There is no air on the moon

Explanation
The reason why the hammer and feather took the same time to reach the surface of the Moon is because there is no air on the Moon. In the absence of air resistance, both objects experience the same acceleration due to gravity and fall at the same rate. This is known as the principle of the equivalence of gravitational and inertial mass, which states that the mass of an object determines how it responds to gravity. Therefore, in the vacuum of space, where there is no air resistance, objects of different masses will fall at the same rate.

Sublimation of an element or compound is the change from a solid directly to a gas with no intermediate liquid stage. Sharada told that if pepper seeds are placed along with camphor, the sublimation of camphor would reduce. Of these boxes, (some are open and some are closed) which two should she use to check whether this is true?
- A.
  
  P and Q
- B.
  
  R and T
- C.
  
  P and S
- D.
  
  Q and S
Correct Answer
C. P and S

Explanation
Sharada's statement suggests that the sublimation of camphor can be affected by the presence of pepper seeds. To test this, she should use boxes P and S. By placing camphor with pepper seeds in box P and camphor alone in box S, she can compare the sublimation rates in the two boxes. If the sublimation of camphor is indeed reduced in the presence of pepper seeds, there should be a noticeable difference in the amount of camphor remaining in each box after a certain period of time.

We know that the pressure of water increases with depth. Then, which of the following shows the most possible shape of a dam?
- A.
  
  A
- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
C. C

Explanation
The most possible shape of a dam would be a shape that can withstand the increasing pressure of water with depth. Option C appears to be a curved shape, which can distribute the pressure more evenly across the dam's surface, making it the most likely choice for a dam design.

Read the question from Image.
- A.
  
  That the barrels used are identical (when empty)
- B.
  
  That the ramps used are identical.
- C.
  
  That the barrels are released simultaneously
- D.
  
  That the barrels are released from the same point.
Correct Answer
C. That the barrels are released simultaneously

Explanation
The correct answer is that the barrels are released simultaneously. This means that both barrels are let go at the exact same time. The other factors mentioned in the question, such as the barrels being identical when empty, the ramps being identical, and the barrels being released from the same point, may also be important for the experiment, but they are not specifically related to the barrels being released at the same time.

Renu has to fill a number of small bottles with juice quickly and with no spillage. Which of these arrangements should she use?
- A.
  
  A
- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
A. A

Explanation
Option A shows a funnel attached to a long tube, which is an ideal arrangement for filling small bottles with juice quickly and without spillage. The funnel helps to direct the flow of juice into the bottles, while the long tube allows Renu to easily reach and fill each bottle without any spillage. Options B, C, and D do not provide any additional tools or mechanisms to aid in the filling process, making them less efficient and more prone to spillage.
