If 185 J went in and 153 J came out (with 32 J lost to heat), the efficiency would be 153/185, 0.827 or 82.7%.

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?
Efficiency = Wout/Win * 100%Efficiency = 170 J/250 J * 100% = 68%
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
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%
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?
30

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 formula?
Efficiency=Useful energy output divided by the energy input. i.e. 100 J is the energy input and you get 5 J light energy from a lamp, the waste energy would be 5 J.

What is the efficiency of an air conditioner if there is a work input of 320 J and a work output of 80 J?
Efficiency = (output/input) x 100 = (80/320) x 100 = 25%
