What is the mechanical efficiency of a machine whose work input is 100 J and work out put is 30 J?
The mechanical efficiency can be calculated using the formula: Efficiency = (Work output / Work input) * 100%. Given the values, we have: Efficiency = (30 J / 100 J) * 100% = 30%. Therefore, the mechanical efficiency of the machine is 30%.
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 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%.
What is the efficiency of an engine that does 288 Juoles of work and exhausts 72 Juoles of heat while taking in 360 J of heat?
The efficiency of the engine can be calculated using the formula: Efficiency = (Work output / Heat input). In this case, the work output is 288 J and the heat input is 360 J, so the efficiency would be (288 J / 360 J) = 0.8, or 80%.
What is the efficiency of a device that takes in 40000 J of heat and does 12000 J of work while giving off 28000 J of heat?
Efficiency is calculated as the ratio of useful work output to the total heat input. In this case, the useful work output is 12000 J, and the total heat input is 40000 J + 28000 J = 68000 J. The efficiency would be (12000 J / 68000 J) * 100% = 17.65%.

What is the value of C if F 185?
185°F is equal to 85°C. To convert F° to C°, subtract 32 and multiply by .5556 (or 5/9).185 - 32 = 153 x .5556 = 85.0068 or 85° rounded down.
What is the efficiency of an engine that does 288 Juoles of work and exhausts 72 Juoles of heat while taking in 360 J of heat?
The efficiency of the engine can be calculated using the formula: Efficiency = (Work output / Heat input). In this case, the work output is 288 J and the heat input is 360 J, so the efficiency would be (288 J / 360 J) = 0.8, or 80%.
A levers efficiency is 95 percent The work in is 95 J What is the work out?
To find the work out, you can use the formula for efficiency: Efficiency = (Work out / Work in) * 100. Given that the efficiency is 95%, you can rearrange the formula to find Work out as follows: Work out = (Efficiency / 100) * Work in. Substituting the values, you get Work out = (0.95) * 95 J = 90.25 J.
What is the efficiency of a device that takes in 40000 J of heat and does 12000 J of work while giving off 28000 J of heat?
Efficiency is calculated as the ratio of useful work output to the total heat input. In this case, the useful work output is 12000 J, and the total heat input is 40000 J + 28000 J = 68000 J. The efficiency would be (12000 J / 68000 J) * 100% = 17.65%.
What A mechanical device requires 420 j of work to do 230 j if work to lift a crate what is the efficiency of the device?
The efficiency of the device is calculated as the output work divided by the input work, then multiplied by 100 to get a percentage. In this case, efficiency = (230 J / 420 J) x 100 = 54.76%.
What is the efficiency percentage of a mechanical device which requires 430 J of work to do 230 J of work in lifting a crate?
The efficiency of the mechanical device is calculated by dividing the output work (230 J) by the input work (430 J) and multiplying by 100. Therefore, the efficiency percentage would be (230 J / 430 J) * 100 = 53.5%.
A mechanical device requires 420 j of work to do 230 j of work in lifting a crate what is the efficiency of the device?
The efficiency is (output energy)/(input energy) = 340/400 = 85%
