What would be the mechanical efficiency as a percentageof a machine that produced an output of 200J with an input of 250J?
The mechanical efficiency of the machine is calculated by dividing the output work by the input work and multiplying by 100 to express it as a percentage. For this scenario, the mechanical efficiency would be (200J/250J) * 100 = 80%.
How do you calculate 200j of work done in 20s?
Work done is calculated using the formula: Work = Force x Distance. If you have the result in joules and the time taken, you can calculate the power using the formula: Power = Work / Time. So, you can determine the power required to do 200j of work in 20s.
Frank does 2400J of work in climbing a set of stairs if he does the work in 6 seconds what is his power output?
Frank's power output is 400 watts (W). This is calculated by dividing the work done (2400 J) by the time taken (6 seconds), which results in a power output of 400 W.
Ahmed inputs 250j of work on a machine Explain why that machine has an output force of 200j?
The output force is less than the input work due to losses in the form of heat, sound, or friction. These losses can occur within the machine or in its surroundings, resulting in a lower output force than the input work. In this case, some of the input work is converted into other forms of energy, leading to an output force of 200J.
What is 10 joules of work in 20 seconds?
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.

Do 100 joules of work in 50 seconds and your power output is?
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
If it takes 5 seconds for you to do 1000j of work's what is your power output?
Power is defined as the rate at which work is done, and it is calculated by dividing the amount of work done by the time it takes to do that work. In this case, if you do 1000 joules of work in 5 seconds, your power output would be 200 watts (1000 joules / 5 seconds = 200 watts). This means you are exerting a power of 200 watts to perform the work.
If you do work on an object in half the time, your power output is?
If you do work on an object in half the time, your power output is twice as high. Power is the rate at which work is done, so if the time to do the work is halved, the power output is doubled to maintain the same amount of work done per unit time.
What is the power output of an engine that does 60 000 joules of work in 10 seconds?
60,000 joules per 10 seconds = 6,000 joules per second = 6,000 watts
A weightlifter is able to lift 250 kg 2.00 m in 2.00 seconds What is his power output?
Power output can be calculated using the formula: Power = Work / Time. The work done in lifting the weight is equal to the gravitational force (weight) multiplied by the height lifted: Work = Force × Distance = (250 kg × 9.81 m/s²) × 2.00 m = 4905 J. Therefore, the power output is 4905 J / 2.00 s = 2452.5 W. So, the weightlifter's power output is approximately 2453 watts.
As the time required for a person to do work increases his power output?
No, as the time required for a person to do work increases, their power output decreases. Power is defined as the amount of work done per unit of time, so the longer it takes to do work, the lower the power output.
It takes the person 5 seconds to move 10 meters What is the power output?
Power output is calculated by dividing the work done by the time taken to do that work. In this case, work done is equal to force multiplied by distance, which is mass multiplied by acceleration due to gravity multiplied by distance. Given that the person takes 5 seconds to move 10 meters, we can calculate the speed at which they are moving. Once we have the speed, we can determine the power output using the formula for power, which is work done divided by time.
