Answer:
option (D
Explanation:
Torque is given by
torque = N x i x A x B x sinФ
where, N is number of turns, A is area, b is the magnetic field and Ф be the angle between the area vector and the magnetic field vector, i be the current.
So, torque depends on the current.

Answer:
Explanation:
As the paint brush is dropped from the top of a tall ladder it started free falling
i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.
We know acceleration due to gravity is the attraction experienced by the object due to earth attraction
Value of acceleration due to gravity is constant i.e. 
Therefore the correct choice is
velocity is increasing and acceleration is constant
