Which of the following is an accurate statement? a. ac generators produce current that is pulsating, but always remains positive. b. step-up voltage transformers have a lower number of turns in the primary than in the secondary winding. c. dc generators produce current with a voltage that changes from positive to negative. d. step-down voltage transformers have a different number of turns in the primary than in the secondary winding, so they change the incoming voltage to a higher voltage.

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.
