Answer:
y=1x+4
Step-by-step explanation:
First, find the slope using the formula of y2-y1/x2-x1
Lastly, use any y point from either points to use as a y int.
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
The answer is 33.6.
Add 6 to 2.4 and you get 8.4.
You then multiply 8.4 to 4 and get 33.6.
