Answer:
Acceleration due to gravity and the height the ball reaches
Explanation:
The potential energy of an object can be determined using its mass and the height of the ball it reaches. It is given by :
Where
m = mass of the ball
g = acceleration due to gravity
h = height reached by the ball
Hence, to find the ball’s potential energy she must know the "acceleration due to gravity and the height the ball reaches". Hence, the correct option is (c).

Given that,
Terminal voltage = 3.200 V
Internal resistance
(a). We need to calculate the current
Using rule of loop
Where, E = emf
R = resistance
r = internal resistance
Put the value into the formula
(b). We need to calculate the terminal voltage
Using formula of terminal voltage
Where, V = terminal voltage
I = current
r = internal resistance
Put the value into the formula
(c). We need to calculate the ratio of the terminal voltage of voltmeter equal to emf
Hence, This is the required solution.
