Ahot reservoir with a temperature of 786 k is 0.32 m away from a cold reservoir with a temperature of 332 k. the two reservoirs are insulated from each other except for a rod of brass (k = 109 w/m-k) that has a cross-sectional area of 0.032 m2. the entire system is allowed to reach a steady-state condition. 1) how much energy is transferred by heat between the hot reservoir and the cold reservoir in ten minutes?

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.)
