Motor convert most of its
electric energy into mechanical energy. <span>Electric motors
make mechanical energy through the interaction between magnetic fields. </span>
Take two magnets and attempt to push their North
poles together. There will be a repulsive force that resists this
motion. Move one North pole near the other magnet's South pole.
There will be an attractive force that pulls them together.
Q = 4.6E-6 C
<span>E = 2.6 kV/mm = 2600 kV/m = 2600000 V/m </span>
<span>ε = 8.85E-12 F/m </span>
<span>E = Q/Aε </span>
<span>A = Q/Eε = 4.6E-6/(2600000*8.85E-12) = 0.2 m^2</span>
The rocky object orbiting in space is most likely referred to as an asteroid.
<h3>What is an Asteroid?</h3>
This is referred to a rocky object which revolve around the sun and are considered too small to be called a planet.
Asteroids was observed with the use of a telescope and is around 250 km wide thereby making it the most appropriate choice.

(a) The capacitance of the capacitor is:
and the voltage applied across its plates is
The relationship between the charge Q on each plate of the capacitor, the capacitance and the voltage is:
and re-arranging it we find the charge stored in the capacitor:
(b) The electrical potential energy stored in a capacitor is given by
where C is the capacitance and V is the voltage. The new voltage is
so the energy stored in the capacitor is
