Arectangular coil of 65 turns, dimensions 0.100 m by 0.200 m, and total resistance 10.0 ? rotates with angular speed 29.5 rad/s about the y axis in a region where a 1.00-t magnetic field is directed along the x axis. the time t = 0 is chosen to be at an instant when the plane of the coil is perpendicular to the direction of b with arrow.

(a) calculate the maximum induced emf in the coil.
v

(b) calculate the maximum rate of change of magnetic flux through the coil.
wb/s

(c) calculate the induced emf at t = 0.050 0 s.
v

(d) calculate the torque exerted by the magnetic field on the coil at the instant when the emf is a maximum.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is
