A 19.5-cm cm-diameter loop of wire is initially oriented perpendicular to a 1.9-TT magnetic field. The loop is rotated so that its plane is parallel to the field direction in 0.17 ss .what is the average induce emf in the loop?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?
