If a car is seen stopped at a stoplight at a certain instant and then it is seen 100m away from the light at some time later, the car must have been at some point between the two observations.
a) moving
b) at rest
c) accelerating
d) in equilibrium

List one type of erosion and describe how it happens?

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
