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?
do not hnow
What power was used if it took 2s?
If work or energy was exerted or transferred in 2 seconds,then the power was(1/2) x (the number of joules of work or energy) watts.
If 600 watts of power are used in 45 seconds how much work was done?
27,000 J
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?
Power = (energy used) / (time to use that much energy) = 40/5 = 8 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
How much work was done to move a 10 N book 5 meters. What power was used if it took 2 sec?
25 newtons
How much power is used to move a 13 N object a distance of 3m in 5 seconds?
Power=(Force X distance) / (time) P= (13N x 3m) / (5 sec) P= 7.8 Watts
What power is used by a machine to perform 800 joules of work in 25 seconds?
Power = energy/time During those 25 seconds, the machine is doing work at the rate of 800/25 = 32 watts. We don't know how much power the machine must consume in order to perform work at that rate, but we know it's more than 32 watts.
If a worker used 6000 joules of work to pull his sled 70 seconds what power does he need?
6000 joules / 70 seconds = 85.71 watts
How energymeter is used instead of wattmeter?
An energy meter measures power and time; a wattmeter measures an instantaneous value of power. Energy = Watt/seconds.
