You have a fixed length of wire and need to design a generator that will produce the greatest peak emf for a given frequency and magnetic field strength.

A 48.0-kg astronaut is in space, far from any objects that would exert a significant gravitational force on him. He would like to move toward his spaceship, but his jet pack is not functioning. He throws a 0.720-kg socket wrench with a velocity of 5.

From the fact that virtually every galaxy is moving away from us and more distant galaxies are moving away from us at a faster rate than closer ones, we conclude that

A uniform electric field is oriented in the - z direction. The magnitude of the electric field is 6500 N/C.
