Two satellites revolve around the earth. satellite a has mass m and has an orbit of radius r. satellite b has mass 6m and an orbit of unknown radius rb. the forces of gravitational attraction between each satellite and the earth is the same. find rb.

What properties of a moving object are used in determining the object's energy of motion

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.
