E = 1 - x/p = 1 - 293/473 = ~0.38
=> The number of joules of montion energy that the engine can obtain from 40,000,000 joules of fuel energy:
N = 0.38 x 40000000 = 15,200,000 (J)
The correct answer is A. 15,200.00
Explain
E= 1 -x/p
X= 293
P= 473 k
E= 1 -x/p = 1 - 293/473. = 0.38
So now E= 0.38 —> 38%
40, 000,000 x 0.38 = 15, 200, 000
