Answer:
I am not sure of the question?
Explanation:
List the question
Maybe you can divide the volts its twelve if you do that but itll show you how much to double it by
Explanation:
PEgrav = m *• g • h
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
