Two cups of tea have the same mass and temperature. They are combined into one larger pot. The larger pot starts at the same temperature as the tea. The larger pot of tea has the same temperature as the original cups of tea. The amount of thermal energy in the larger pot of tea is aboutthe amount of thermal energy in each of the smaller cups of tea. A. same as B. twice C. one-half​

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final
