Answer:
265 J
Explanation:
where KE is kinetic energy, PE is potential energy, m is the mass of an object, v is the speed, h is the height and g is acceleration due to gravity.
Substituting 19.7 Kg for mass, 0.934 for h, 2.93 for v and 9.81 for g then

Answer:
Potential
Explanation:
Potential difference is otherwise known as voltage. With no voltage flowing through a conductor a current will not flow.
