Solution
Work out put = 500x1.5 =170
Work input=1000j
Efficiency= work output/work input x 100
=500/1000 x 100=75%
Work out put = 500x1.5 =170
Work input=1000j
Efficiency= work output/work input x 100
=500/1000 x 100=75%
Damon
work out = 500 * 1.5 = 750 Joules
work in = 1000 Joules
so
750/1000 = 0.75 = 75%
work in = 1000 Joules
so
750/1000 = 0.75 = 75%
