Which of the following is an accurate statement? A. Step-up voltage transformers have fewer turns in the primary that in the secondary winding. B. aC generators produce current that's pulsating but always remains positive C. Step-down voltage transformers have a different number of turns in the primary than in the secondary winding, so they change the incoming collage to a higher voltage D. DC generators produce current with a voltage that changes from positive to negative

Option A is an accurate one.

Explanation:

The other provided alternative is not related to the information provided there. So the response to the above seems to be the correct one.

no simpler subs form complex ones. synthesise = make

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.
