6. Which statement about energy is true? A. Energy is a wave. B. Energy cannot travel through a vacuum. C. Energy has the ability to cause motion. D. Energy cannot change form.

C.

Explanation:

There is such thing a wave energy, but that doesn't quite fit for this question. B. I have not heard of that, so it has to be incorrect. C.  Yes, energy can cause motion in a lot of ways. D. Energy can change forms so that is incorrect.

iron would move it is magnetic there is a mag field around the current in the wire

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
