a steam engine does 12 kJ or work in 55 s. how much power does the engine produce?
Answer:
Power, P = 218.18 watts
Explanation:
It is given that,
Work done by the steam engine, \(W=12\ kJ=12\times 10^3\ J\)
Time taken to do work, t = 55 seconds
Power produced by the engine is given by work done divided by time taken i.e.
\(P=\dfrac{W}{t}\)
\(P=\dfrac{12\times 10^3\ J}{55\ s}\)
P = 218.18 watts
Hence, this is the required solution.
