Answer:
455Joules
Explanation:
Efficiency is expressed as;
Efficiency = Work output/Work input × 100%
Given
Efficiency = 35%
Work input = 1.3kJ = 1300Joules
Required
Work output
Substitute into the formula to get work output as shown:
35 = work output/1300 × 100
35 = work output/13
Work output = 35×13
Work output = 455Joules
Hence the machine will produce 455Joules of work
