How does electromagnetic induction in a moving loop of wire cause an electric generator to produce an electric current?
A. Mechanical energy flows out of the magnets and into the electric
charges in the loop of wire.
B. Charged particles flow within the wire because they are pushed by
the magnetic field of the magnets.
C. Charged particles flow when the loop of wire is attracted by the
magnetic field of the magnets.
O D. Electrons flow from the magnets into the loop of wire and
continue to flow within the wire.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.

Your friend increases her force on the desk by 30n . she doesn't change the direction of her push . what happens to the net force on the desk .will the desk accelerate

Afisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. it takes a time of 2.70 s for the boat to travel from its highest point to its lowest, a total distance of 0.700 m. the fisherman sees that the wave crests are spaced a horizontal distance of 6.50 m apart. a. how fast are the waves traveling? b. what is the amplitude a of each wave?
