A U-tube open at both ends is partially filled with water (density of water = 1000 kg/m3). The right arm is shielded from any air motion, while air (density of air = 1.2 kg/m3) is blown across the top of the left arm at 20 m/s. What is the height difference between the surfaces in the U-tube?

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?
