A0.19-kg stone is held 1.1 m above the top edge of a water well and then dropped into it. the well has a depth of 4.6 m. relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stone−earth system before the stone is released?

2.048 J

Explanation:

mass of stone, m = 0.19 kg

h = 1.1 m

g = 9.8 m/s^2

Gravitational potential energy, U = m x g x h

U = 0.19 x 9.8 x 1.1

U = 2.048 J

Thus, the potential energy of the stone is 2.048 J.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
