Answer:
in a magnet there is a magnetic field that draws ever mental to it
When a dielectric material is inserted between two plates of capacitor that are connected to a battery, you would observe that both the charge and the capacitance of the capacitor would change. This is due to the dielectric material which is able to transmit electric force.
P (momentum) = mass x velocity
p = .5 x 20
p = 10
