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
To balance an equation, you do whatever you did on one side, on the other side. If you subtract, then you subtract on the other side. If you multiply, you multiply on the other side, etc...
