Answer:
First you need to have a graph, a x and y graph. Then you start in the very middle of the graph because that is 0,0. So then you take the 9 because it is the x-cordinate and you go 9 to the right from 0,0. Then you go 22 up on the graph because it is thy y-coordinate. Do the same thing for the next one. Start in the middle at 0,0 and then move 10 to the right and 32 up. Do the same for the rest. Hope this helped. :)

Answer:
a) How much work has he done = dW = 1.3 × 105 J
b) What is the magnitude of the heat that he has lost = dQ = -5.4 × 105 J
Step-by-step explanation:
- From the first law of thermodynamics; dQ = dU + dW
Hence, work done dW = dQ - dU
dW = -6.7 × 105 J - ( -8.0 × 105 J)
dW = 1.3 × 105 J is the work done by the player
- for heat lost; from dQ = dW + dU
- dU = -8.0 × 105 J and dW = 2.6 × 105 J
- heat lost dQ = 2.6 × 105 J + ( -8.0 × 105 J)
- The negative is as a result of heat lost by the player
