An individual electron can be thought of as a spinning sphere of negative charge. a charged spinning sphere will generate a magnetic field, whose direction is indicated by the magnetic moment of the object, vector mu. in what direction will the electron rotate, based on the direction of its magnetic moment and the direction of the uniform magnetic field that it is immersed in?
a) clockwiseb) it will rotate into and out of the pagec) it will not reorient itselfd) counter-clockwise

The two required components for a generator are

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
