Which procedure would best demonstrate that a moving magnet causes an electric current to flow in a wire coil?
A. Connect a battery to a wire and an ammeter. Move a bar magnet in circles around the battery as you observe the ammeter
B. Connect a wire to a lightbulb and a bar magnet. Turn on the switch as you observe the lightbulb.
C. Connect a wire coil to an ammeter. Move a bar magnet into and out of the wire coil as you observe the ammeter
D. Connect a wire to a lightbulb, a battery, and a magnet on a rotating turntable. Turn on the switch as you observe the lightbulb.

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
