The correct order of comparison for the terminal speeds of a raindrop, snowflake, and hailstone is:

 
 
 
 

If a body is at rest or moving with uniform rotational velocity, then torque acting on the body will be:

 
 
 
 

It is more difficult to walk on a slippery surface than on a non-slippery one because of:

 
 
 
 

When the line of action of the applied force passes through its pivot point then the moment of force acting on the body is:

 
 
 
 

For an object moving with terminal velocity, its acceleration:

 
 
 
 

A satellite of mass ‘m’ is revolving around the Earth with an orbital speed V. If the mass of the satellite is doubled, its orbital speed will become:

 
 
 
 

You are trying to loosen a nut using a spanner, but it is not working. In order to open the nut, you need to:

 
 
 
 

A uniformly rotating fan is said to be in:

 
 
 
 

The reason that a car moving on a horizontal road gets thrown out of the road while taking a turn is:

 
 
 
 

The force that always changes the direction of velocity and not its magnitude is called:

 
 
 
 

Seesaw balances perfectly with two children of equal weight sitting at equal distances from the fulcrum. If one child moves closer to the fulcrum:

 
 
 
 

A car drives at a steady speed around a perfectly circular track.

 
 
 
 

A tightrope walker is carrying a long pole while walking across a rope. The stability of the walker is affected if the pole is:

 
 
 
 

A body in equilibrium must not have:

 
 
 
 

You throw a weighted fishing net into a calm lake. As the net sinks, it opens fully underwater, spreading out its mesh evenly. Compared to the moment it left your hand, where is the net’s center of mass now?
