Question: (a) Using elementary Newtonian mechanics find the period of a mass m1 in a circular orbit of radiusr around a fixed mass m2.
(b) Using the reduced-mass formalism, find the corresponding period for the case that m2 is notfixed and the masses move around their CM being a constant distance r apart. Discuss the limitof this result if m2 >> m1.
(c) What would be the orbital period if the earth were replaced by a star of mass equal to the solarmass, in a circular orbit, with the distance between the sun and star equal to the present earth-sundistance?
An ice cube of mass 0.018 kg, at the temperature of the freezing point of water, is surrounded by water at a temperature just above the freezing point. What is the change in entropy of the ice cube as it melts? (The latent heat of fusion of water at ..

An air-filled parallel plate capacitor with a plate spacing of 1.20 cm has a capacitance of 6.00 uF. The plate spacingis now doubled and a dielectric is inserted, completely filling the space between the plates.
A solid cylinder, a hollow cylinder, a solid sphere and a hollow sphere of the same mass and radius are placed on an incline and a released simultaneously from the same height. In which order would these bodies reach the bottom of the incline?
A pendulum bob with a mass of 0.39 kg is attached to a 1.5 m long string as shown. As the pendulum bob swings from point A, where the angle is (theta) =37 degrees, to point B at the bottom of its arc, decide the change in its gravitational potential ..
A 7.00g coin is placed 17.0cm from the center of a turntable. What is the maximum angular velocity with which the turntable can spin without the coin sliding
A circuit is pulled with a 16-N force toward the right to maintain a constant speed v. The loop is partially in and partially out of a uniform magnetic field that is directed into the paper. Because the circuit moves, a 6.0 A current flows during a 4..
