Arectangular coil with sides 0.190 m by 0.220 m has 501 turns of wire. it is rotated about its long axis in a uniform magnetic field of 0.550 t that is perpendicular to the long axis. at what frequency, in complete cycles per second, must the coil be rotated for it to generate a maximum voltage of 115 v?

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud
