PLEASE help if you can!! Most electric motors use electromagnets instead of permanent magnets. State 3 of the features of an electromagnet which control the strength of the magnetic field obtained​

the answer is kevlar

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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.

mass:
