A 10 turn square coil has an area 14.0 cm2 and is rotated by an angular speed of190.0 rad/s in a uniform 0.10 T magnetic field. The axis of the coil is perpendicular to the field at all times. What is the frequency of the sinusoidal voltage induced across its ends?
What is the peak voltage induced across the ends of the coil?
How is the induced emf related to the flux?
What is the flux during the coil when the plane of the coil is inclined at 36.0° to the magnetic field?
If the coil forms a closed circuit with a series resistance of 40.0 W, what is the instantaneous power being dissipated in the resistor when the plane of the coil makes an angle of 36.0° by the magnetic field?
What is the average power dissipated in the resistor?
Determine the energy of the incident electron. How many coulombs of protons and electrons are in each penny.
Ball of mass "m" hangs on a string of length L` straight down from a cart of mass M standing on horizontal rails. The cart can move along the rails without friction. While the cart is at rest, the ball is given a horizontal velocity v0, v0
In a torus of inner radius 1.0m and outer radius 1.5m, a toroidal magnetic field of strength 5.0 tesla is required in the middle (i.e at R = 1.25m). Calculate the current that must pass through the wire to produce the required magnetic field
A 35.0g bullet moving at 475 m/s strikes a 2.5kg bag of flourthat is on ice, at rest. The bullet passes through the bag, andexits it at 275 m/s. How fast is the bag moving when the bulletexits?
