A square coil, enclosing an area with sides 3.4 cm long, is wrapped with 2,224 turns of wire. A uniform magnetic field perpendicular to its plane is turned on and increases to 0.26 T during an interval of 1.2 s. What average voltage is induced in the coil? Express the answer with two decimal places.
What is the force exerted on beam by the fixture P (P is where the beam is attached horizontally to the brick wall) at the wall (magnitude and direction).
A small sphere of mass m = 6.10 g and charge q1 = 29.2 nC is attached to the end of a string and hangs vertically. A second charge of equal mass and charge q2 = 58.0 nC is located below the first charge a distance d = 2.00 cm below the first charg..

A Carnot air conditioner takes energy from the thermal energy of a room at 294 k and transfers it as heat to the outdoors, which is at 309 k. for eacg joule of electric energy needed to operate the air conditioner, how many joules are removed from..
what is the linear speed of the fishing line. The force exerted by the wind on the sails of a sailboat is 300 N north. The water exerts a force of 150 N east. If the boat (including its crew) has a mass of 300 kg, what are the magnitude and directi..
A pendulum of length 1.5 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 1.09 m. (That is, 1.0 m is no longer free to swing.) How long does this pendulum take for one o..
Now assume the particle is a proton and that its initial velocity is 254.7 m/s to the right. If the magnitude of the magnetic field is 0.98 T
