Dylan puts two magnetic toy trains very close to each other on a track. What will happen next, and -hy?
a
The trains will not move because the magnets are not touching.
b
The trains will move closer to each other because the magnetic force will pull the trains
together
с
The trains will move away from each other because the magnetic force will push the trains
apart.
d
The trains will move away from each other because the magnets are not touching.

the answer is b

explanation:

the correct choice is a .

do not post any more test or exam questions on

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:
