Answer :
Answer: 9.9%
Explanation: efficiency = (work output /work input) × 100
Note that, 1 kilocalorie = 4184 joules, hence 22kcal = 22× 4184 = 92048 joules.
Work output = 9200 j and work input = 92048 j
Efficiency = (9200/92048) × 100 = 0.099 × 100 = 9.9%
The efficiency of this engine is 9.9%.
Efficiency = (work output /work input) × 100
1 kilocalorie = 4184 joules.
22kcal = 22× 4184
= 92048 joules.
Work output = 9200 J and work input = 92048 J
Efficiency = (9200/92048) × 100
= 0.099 × 100
= 9.9%
