What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 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.
Can an amount be decreased by more than 100 percent?
No, an amount cannot be decreased by more than 100 percent. To decrease by more than 100 percent would mean that the amount is actually going into the negative values, which is not possible in most contexts. A decrease of 100 percent means that the amount is reduced to zero.
What is the formula to calculate percent efficiency?
(work out/work in) x 100
Can 120 percent be a probabilty?
No. No percentage higher than 100 percent is possible. Out of 100 occurrences it is impossible to obtain an answer of more than the totality of the occurrences.
What would cause the calorimeter efficiency to be less than 100 percent?
why is the efficiency of a calorimeter less than 100%
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
Can a machine have 110 percent efficiency?
No, a machine cannot have 110 percent efficiency. Efficiency is calculated as output divided by input, with 100 percent being the maximum achievable efficiency. Having a value higher than 100 percent would imply that the machine is producing more output than the input provided, which is not physically possible.
Does a refrigerator have 100 percent efficiency?
nothing has 100% efficiency.
If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?
No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
Can a machine's efficiency can be greater than 100 percent?
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
The efficiency of an actual machine is always less than what percent?
The efficiency of an actual machine is always less than 100 percent, as no machine can convert all input energy into useful output energy due to factors like friction, heat loss, and inefficiencies in the system.
What is the formula for calculating efficiency?
General formula for calculating efficiency is given by Efficiency = (output / input) * 100 It is denoted by greek letter Eta Efficiency cannot be more than 100%.
Why is efficiency of machine not 100?
If there would be a machine with an efficiency of 100 you would have perpetual motion. Some energy must be lost to friction, heat, gravitational pull.Boss if you have efficiency more than 100 % that means your output is more than input, so from where the excess energy you get ...?
Can a car have a 100 percent efficiency?
No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.
Can a machine be more than 100 percent efficient?
100% efficiency would mean that the machine is able to transform energy from one form into another without any loss of energy from the system in the process. For it to have greater than 100% efficiency, it would have to somehow generate additional energy, not contained in the system, in the process, and this is not possible.
