Consider the arrangement shown in the figure below. Assume R = 4.0 ? and = 1.4 m, and a uniform 2.4 T magnetic field is directed into the page. At what speed should the bar be moved to produce a current of 0.60 A in

1. Student observed ten antinodes on a string of length 1.70 m under tension produced by a mass of 0.22 kg. The string linear density is 1.3 gram/meter. What is the difference between the transverse wave velocity calculated from the string material properties and the

A uniform spherical shell of mass M = 3.0kgand radius R = 13.0cmcan rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 1.36�10 -3 kg�m

A capacitor is attached to a 8.39-Hz generator. The instantaneous current is observed to reach a maximum value at a certain time. What is the least amount of time that passes before the instantaneous voltage across the capacitor reaches its maximum value?

A capacitor C is charged to an initial potential of 60.0 V, with an initial charge of Q0. It is in a circuit with a switch and an inductor with inductance L = 3.69�10 -2 H and resistance RL.

A drug tagged with 99 43Tc (half-life = 6.05 h) is prepared for a patient. If the original activity of the sample was 1.8 10 4 Bq, what is its activity (R) after it has been on the shelf for 2.0 h? Answer in Bq

The left end of a long glass rod 8.00cm in diameter and with an index of refraction of 1.60 is ground and polished to a convex hemispherical surface with a radius of 4.00cm . An object in the form of an arrow 1.30mm tall, at

A large aquarium has portholes of thin transparent plastic with a radius of curvature of 1.85m and their convex sides facing into the water. A shark hovers in front of a porthole, sizing up the dinner prospects outside the tank.

Two thin lenses with a focal length of magnitude 10.5cm , the first diverging and the second converging, are located 7.88cm apart. An object 3.50mm tall is placed 17.5cm to the left of the first (diverging) lens.

A nuclear reactor has a total power output (i.e. the total output of heat, radiation, and nuclear energy) of 2.0GW (2.00E9 W). How much mass converted to energy does this represent of the reactor operates for one year?
