Answer:
The moon's revolution around its axis and the moon's revolution around the Earth take the same time, approximately 27 days. That causes one side of the Moon to always face the Earth while the other side always faces away from the Earth. That is why it took probes to go into space to photograph the side that is never visible from Earth for people to be able to see it.
Answer:
|q1|/|q2| = 1/7
Explanation:
Particle 1 experiences a force F1 due to the magnetic field, B:
F1 = |q1|*v1*B
Particle 2 experiences a force F2 due to the magnetic field, B:
F2 = |q2|*v2*B
We're given that:
v1 = 7v2
Also, the force experience by both particles are equal:
F1 = F2
=> |q1|*v1*B = |q2|*v2*B
|q1|/|q2| = v2/v1
=> |q1|/|q2| = v2/7v2
=> |q1|/|q2| = 1/7
