Extreme pressure in the sea is<span> the energy source that resulted in compression of tiny sea creatures into fossils, over millions of years. These creatures got buried under the ocean or river sediments, and the pressure caused their compression, leading to the formation of oil and natural gas.</span>
Answer:
Explanation:
Let us calculate gallon used in one hour .
It travels 70 miles in one hour
in 70 miles it uses 70 / 34 gallons of fuel
70 / 34 gallons = 70 / 34 x 3.7854 kg
= 7.8 kg
heat generated = 7.8 x 44 x 10⁶ J
= 343.2 x 10⁶ J
This is heat generated in one hour
heat generated in one second = 343.2 x 10⁶ / 60 x 60 J/s
= 95.33 x 10³ J /s
= 95.33 kW.
