Answer :
efficiency is (output/input) x 100
the efficiency is 33.33%
the efficiency is 33.33%
Answer:
Efficiency of an engine is 33.34 %
Explanation:
It is given that,
Input work, W₁ = 300 Joules
Output work, W₂ = 100 Joules
We have to find the efficiency of the engine. The efficiency of engine is given by the ratio of output work to the input work. Mathematically, it is given by :
[tex]\eta=\dfrac{w_2}{w_1}\times 100[/tex]
[tex]\eta=\dfrac{100}{300}\times 100[/tex]
[tex]\eta=33.34\%[/tex]
Hence, the efficiency of the engine is 33.34 %
