The idea is to divide the useful work by the input energy.
useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100
The efficiency is always less than one because some of the energy is always useless for what you want. Most wasted energy eventually turns into heat. therefore the efficiency is like a percentage with 1 being 100% a device can't be 100% efficient as some energy is wasted. To work out the efficiency of a device you need to do the total useful energy produced divided by the total energy that is inputted into the device
sanky diagrams are used accurately to show energy or materials. They can also show whether energy is useful or not :] Emleigh x p.s - random but i love christian :] <3 x
Most useful and more useful.
more useful, most useful
The efficiency of the machine can be calculated by dividing the useful work output by the total input energy and multiplying by 100. In this case, the efficiency would be (35/100) * 100 = 35%.
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.
The efficiency of the machine is calculated by dividing the useful work output by the total input energy and multiplying by 100. Therefore, the efficiency of the machine in this case is (35 J / 100 J) * 100% = 35%.
The efficiency of a machine is a measure of how well it converts input energy into useful work output. It is calculated as the ratio of useful work output to the total input energy or power. A high efficiency indicates that the machine is able to minimize energy losses and perform its intended function effectively.
High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.
To calculate a machine's efficiency, you need to know the input energy (total energy put into the machine) and the output energy (useful energy the machine produces). Efficiency is usually calculated as the output energy divided by the input energy, multiplied by 100 to get a percentage.
To calculate the efficiency of a machine, you need to know the amount of useful work output produced by the machine and the amount of total energy input supplied to the machine. Efficiency is calculated by dividing the useful work output by the total energy input and multiplying by 100 to express it as a percentage.
Efficiency is indeed a measure of how well a machine converts input energy into useful output. It is calculated by dividing the useful output by the total input. Higher efficiency indicates better performance and less wasted energy.
The idea here is to divide the useful work by the input energy. (Note: Usually "power" would be used instead of "energy"; power is measured in joules/second.)
The efficiency of a machine is the ratio of its useful energy output to the total energy input. A higher efficiency value indicates that the machine is converting more of the input energy into useful work output. Efficient machines help minimize energy wastage and improve performance.
The efficiency of the simple machine is calculated as the useful energy output divided by the total energy input, multiplied by 100%. In this case, the efficiency would be (100 J / 200 J) x 100% = 50%.
