Question

What is the answer of it​

Answer 1

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


Hope this help you

Stay safe :D

Answer 2

Option A

Explanation:

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)
