Consider the relative motion of two equal mass particles. a) determine the required constant angular velocity co of the rel- aeive posi ative position vector in order to maintain a constant separation distance ro. determine the value of ao for unequal masses mi and m2. 1 b)

Rohit is trying to tune an instrument

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
