5. Why does a magnet hanging from a string point north? The movement of liquid metal in Earth's core creates a magnetic field.
Earth's north pole is made of iron.
The string is affected by a magnetic field.
There is a giant bar magnet in the center of Earth.

we can see how the government has failed them.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
