Calculate the kinetic energy of a 5.0kg object moving at 4.0 m/s

The dot diagram represents the motion of the motorcycle as it moves from left to right

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.

What do we mean by the event horizon of a black hole?
