A machine require 100J of work to raise a load of 500N through a vertical distance of 1.5M CAL the of the machine

and the question is?

To calculate the efficiency of a machine, we need to determine the work input and work output.

In this case, the work input is given as 100J. We also know the load (force) of 500N and the vertical distance of 1.5m.

The work output can be calculated using the formula: Work = Force * Distance.

So, the work output = 500N * 1.5m = 750J.

Now, we can calculate the efficiency of the machine using the formula: Efficiency = (Work output / Work input) * 100.

Efficiency = (750J / 100J) * 100 = 750%.

Therefore, the efficiency of the machine is 750%.
