Two reversible heat engines operate in series between a source at 527oC and a sink at 17oC. If the engines have equal efficiencies and the first rejects 400 kJ to the second, calculate. V P A B C D 500 K 200 K Net work done = 60.0 J Heat bath at TH Heat bath at TL Heat Pump w qL qH Page 15 of 17 (a) The temperature at which heat is supplied to the second engine; (b) The heat taken from the source; (c) The work done by each engine

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
