2 answers:
750W 30mins...750x30x60 joules ... 75000x18 ... about 1,500,000j
D
Answer:
1,350,000Joules
Explanation:
Work done by Joe in 30minutes can be calculated using the formula
Work done = power × time
Given power = 750watts
Time = 30minutes
Time = 30×60 = 1800secs
Workdone = 750×1800
Work done by Joe= 1,350,000Joules
