The image shows a dam. which descriptions best fit the labels?
x: kinetic energy
y: potential energy
x: potential energy
y: kinetic energy
x: mechanical energy
y: electrical energy
x: electrical energy
y: mechanical energy

X: potential energy

Y: kinetic energy

Explanation:

At x water is held at a height relative to the turbines the water turns. Water is then forced by gravity to move down the dam to try to reduce the potential energy and create an equilibrium.

This process transforms potential energy into kinetic energy once the water is set in motion.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
