What is the efficiency of a motor that converts 100J of electric energy into 70j of useful energy?
The efficiency of the motor can be calculated by dividing the useful energy output by the total energy input and multiplying by 100. In this case, the efficiency would be 70J (useful energy output) divided by 100J (total energy input) = 0.7 or 70%.
If a system requires 150j on input work and produces 123j of output work what is the efficiency?
The efficiency of the system would be calculated as the ratio of output work to input work, multiplied by 100% to express it as a percentage. In this case, the efficiency would be 82% (123j output work / 150j input work) * 100%.
What is the efficiency of a pulley that requires a worker to do 250 j of work to lift an object that requires 170 j or work?
The efficiency of the pulley system is calculated by dividing the output work by the input work and multiplying by 100, so efficiency = (output work/input work) * 100. In this case, the output work is 170 J and the input work is 250 J, so the efficiency is (170/250) * 100 = 68%.
If a system requires 150 j of input work and produces 123 j of output work what's it's efficiency?
The efficiency of the system can be calculated using the formula: efficiency = (output work / input work) * 100%. In this case, the efficiency would be (123 J / 150 J) * 100% = 82%.
What is the formula to finding the work output of efficiency?
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
What is the efficiency of a motor that converts 100J of electric energy into 70j of useful energy?
The efficiency of the motor can be calculated by dividing the useful energy output by the total energy input and multiplying by 100. In this case, the efficiency would be 70J (useful energy output) divided by 100J (total energy input) = 0.7 or 70%.

What is the efficiency of a machine that requires 120J of input energy to do 35 J of useful work?
The idea is to divide the useful work by the input energy.
If a system requires 150 j of input work and produces 123 j of output work what's it's efficiency?
The efficiency of the system can be calculated using the formula: efficiency = (output work / input work) * 100%. In this case, the efficiency would be (123 J / 150 J) * 100% = 82%.
A man expends 100j of work to move a box up an inclined plane the amount of work produced is 80j what is the efficiency?
50
A man expends 100j of work to move a box up a inclined plane. the amount of work produced is 80j. what is the efficiency of the machine?
80%
What is the formula to finding the work output of efficiency?
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
What happens if you increase the efficiency of a simple machine?
Increasing the efficiency of a simple machine means that it requires less input work to produce the same output work. This results in less wasted energy and ultimately allows the machine to do more work with the same amount of input.
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
