Answer: E = 1.62*10^-3 v
Explanation:
Given
L = 1.9 m
V = 19 m/s
B = 4.5*10^-5 T
Induced emf can be found by using the formula for induced emf in a moving conductor.
e = blv, where
B is the component of the earth's magnetic field.
L is the width of the car in m
V is the velocity of the car in m/s
E is the induced emf in volts.
E = 4.5*10^-5 * 1.9 * 19
E = 1.62*10^-3 v
The drivers side is more positive, so the charge would remain positive
The reference point is wherever you want it to be. If you define it
as the tip of the nose of one of the people, that's fine. Alternately,
it could be one of the claws on the dog across the street, or a leaf
on the tree that's directly over the people.
Since you're planning on describing the motion of the car, you
probably don't want to pick the car itself as the reference point.
If you did that, then the car would never move, but everything else
would.

Answer:
The answer is the third option, the minimum force required to overcome static friction and move an object.
Explanation:
The first choice is talking about an object moving, and anything moving relates to <em>kinetic </em>friction, not static friction. I don't think it's the fourth option because, even with the net force being 0, the object could still be moving (again relating to kinetic friction).
