What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
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 of a machine is defined as?
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.
What must you know in order yo calculate a machine's efficiency?
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.
What do you need to know to calculate the efficiency of a machine?
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.
Is A measure of how well a machine operates is its efficiency?
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.
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.
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
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%.
What is an efficiency ratio?
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.
Why does a high-efficiency machine is more desirable than low-efficiency machine?
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.

What percentage of energy is converted into useful energy?
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.

What is the efficiency of a machine that requires 150 J of input energy to do 20 J of useful work?
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.)
When the useful energy output of a simple machine is 100 J and the total energy input is 200 J the efficiency is .?
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%.
The of a machine is the ratio of its energy output to the energy input?
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.
