Copper has a specific heat of 0.09 cal/g x c . how much change in temperature would the addition of 8373 cal of heat have on a 538.0 gram sample of copper

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.
