Answer:
Height and mass
Explanation:
The potential energy of a body is the energy due to the position of a body.
It is mathematically expressed as:
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
Acceleration due to gravity on the earth surface is a constant.
As mass and height of a body increases, the acceleration due to gravity will also increase.
Option D.
A voltaic cell need tha anode, the cathode and the electrolyt to work.
Volitmeter is just an equipment to measure the functioning of the voltaic cell.
