All of the arrows in the bar magnet are pointing in the same direction to represent that a) all of the metals are crystally aligned. b) all of the atoms are pointing in the same direction. c) all of the electricity is flowing in the same direction. d) all of the unpaired electrons spinning in the same direction.

answer is all of the unpaired electrons spinning in the same direction

Explanation:

The arrows pointing in the same direction represent all of the unpaired electrons spinning in the same direction. This is what creates the magnetic domain of the bar magnet.

The arrows pointing in the same direction represent all of the unpaired electrons spinning in the same direction. This is what creates the magnetic domain of the bar magnet.

D)

the force on the thing and the distance the force moves the thing

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.
