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)


A 50 N girl climbs the flight of stairs in 3 seconds how much power is used?

Power is calculated using the formula ( P = \frac{W}{t} ), where ( W ) is the work done and ( t ) is the time taken. The work done in climbing the stairs is equal to the gravitational potential energy gained, which is ( W = F \times d ). However, without the height (or distance) climbed, we can't calculate the exact work done. If the height is known, you can substitute the values into the formula to find the power used.
