How much power is used to move a 25kg mass 8 meters in 15 seconds?
.47 watt
How much power is used if the 950 N person lifted 3 meters?
To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.
What ratio is used to convert seconds to minutes?
Some seconds (1 minute/60 seconds)
What is the power in watts when 7500 J of energy are used in 5 h?
Although most of the time power is measured in Watts, it can also be expressed as Js-1. So in your question, you are given the amount of joules and the time in hours. First, convert 5 hours to seconds. There are 60 mins in an hour and 60 seconds in a minute. So that's going to be 5x60x60 = 18000 seconds Now all you do in divide the number of joules by the number of seconds to work out the power. So that's 7500/18000 = 0.41666666666... approximately, 0.42Js-1(2dp) and thats the same as 0.42W (2dp)
How much power is used when 600j of work are done in 10seconds?
Use the definition of power as energy / time. Or work / time; it's basically the same thing.
How much power was used if it took them 60s?

How much power is used when Joules of work are done in 10 seconds?
Power is calculated by dividing the work done in Joules by the time taken in seconds. So, if x Joules of work are done in 10 seconds, the power used would be x/10 watts.
What power was used if it took 2s?
We would need more information to determine the power used. Power is calculated by the formula: Power = Work / Time. If you provide the amount of work done within the 2 seconds, then we can calculate the power used.
How much power is used when 600 joules of work are done in ten seconds?
The power used would be 60 watts. This can be calculated by dividing the work done (600 joules) by the time taken (10 seconds).
What is the power used if it took 2000j to move a box of 8s?
The power used to move the box would be 250 Watts. This is calculated by dividing the energy (2000 Joules) by the time taken (8 seconds).
How much power is used to move a 25kg mass 8 meters in 15 seconds?
.47 watt
How much power is required to do 40 J of work on an object in 5 seconds?
The power required to do 40 J of work in 5 seconds is 8 watts. This can be calculated by dividing the work (40 J) by the time (5 seconds). The formula for power is Power = Work / Time.
How much power is used when 600 J of work are done in 10 seconds?
The power used would be 60 watts. This can be calculated by dividing the work done (600 J) by the time taken (10 seconds), resulting in 60 watts.
How much power is used to lift a piano weighting 1000 newtons 3 meters in 60 seconds?
3000
A blender has a power of 0.3 kW. It is used to make a fruit smoothie, which takes 50 seconds. How much energy is used Give your answer in kilojoules.kJ?
15 KJ
If 478 Watts of power are used in 14 seconds how much work was done?
The work done can be calculated using the formula: work = power × time. Substituting the given values, the work done would be 478 Watts × 14 seconds = 6692 Joules.
How much power is used (in watts) when 120 joules of work is done in 1 minute?
Power is the rate at which work is done, given by the formula Power = Work/Time. In this case, Power = 120 Joules / 60 seconds = 2 Watts.
