Why do electric charges that move through a magnetic field produce an electric current?
A. The magnetic field pushes negative charges and positive charges
in opposite directions.
B. The magnetic field exerts a force only the negative charges in
the wire.
O C. The magnetic field exerts a force on only the positive charges in
the wire.
D. The magnetic field pushes negative charges and positive charges
in the same direction.

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.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
