Question

expression of potential energy​

Answer 1

Potential energy is energy an object has because of its position relative to some other object. ... For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Answer 2

Here's your answer friend:-

definition of Volt:-

in a electrical circuit V=W/q

W=1,q=1 then,

V=1 (1 volt)

expression of potential difference = 'V'

1mV=10^-3volt

1μV=10^-6volt

1kV=10^3 volt

1MV=10^6 volt
