A body is dropped from rest at a height of 80m. how kind does it take to reach the ground (g=10m/s²)

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?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

True or false graphs must include scales that increase by the same amount
