What is the efficiency of a ramp if 2,000 joules of energy results in 1,200 joules of work?(1 point) Responses 24% 24% 60% 60% 32% 32% 80%
1 answer
The efficiency of the ramp would be 60%. This is calculated by taking the ratio of the work output to the energy input and multiplying by 100. In this case, (1200/2000) x 100 = 60%.
