Question

If the energy input of an engine is 6,000 J and its efficiency is 33%, calculate its energy output. Eout = ______ J 200 2000 3000 4000

Answer 1

The answer to the question is 2,000 J. Hope this helps!

Answer 2

Answer:

Output energy of the engine is 2000 J.

Explanation:

It is given that,

Input energy of an engine is $E_i=6000\ J$

Efficiency of the engine is 33 %

We have to find the output energy of the engine. Efficiency of the engine is given by the ratio of output energy to the input energy i.e

$\eta=\dfrac{E_o}{E_i}$

$\dfrac{33}{100}=\dfrac{E_o}{600\ J}$

$E_o=\dfrac{33\times 6000}{100}=1980\ J$

or $E_o=2000\ J$

Hence, this is the required solution.
