How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
What formula is e equals pt?
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
Find the work you do when you exert a force of 40 N to run a distance of 18 m in 4 seconds?
The work is Work= FD= 40x18= 720 Joules. The power is W/seconds = 720/4= 180 Watts.
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 long does it take a 19 kW steam engine to do 6.8 x 10 to the seventh power J of work?
19 KW = 19,000 Joules per second.6.8 x 107 / 19,000 = 3,578.95 seconds, at the rate of 19 KW.That's 21.05 seconds short of 1 hour. In exactly 1 full hour, the engine delivers 6.84 x 107 joules.
How much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
How long does it take to perform 475 Joules of work with 25 watts of power?
To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.
How long does it take to perform 500 Joules of work with 25 watts of power?
To find the time taken to perform 500 joules of work at a power of 25 watts, you divide the work by the power. In this case, 500 Joules / 25 watts = 20 seconds. Therefore, it would take 20 seconds to perform 500 Joules of work with 25 watts of power.
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
How much power in needed to produce 1700 Joules in 5 seconds?
The power needed can be calculated using the formula: Power = Energy / Time. Plugging in the given values, the power required to produce 1700 Joules in 5 seconds is 340 Watts.
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
How much power is needed to perform 600 Joules of work in 150 seconds?
Power = Work / time= 600 J / 150 secPower = 4 J/s or 4 Watts (1 Watt = 1 J/s)
How much power is necessary to do 60 joules of work in 20 seconds?
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
How long does it take to perform 480 Joules of work with 20 watts of power?
To calculate the time taken to perform work with a certain amount of power, you can use the formula: time = work / power. In this case, the time taken to perform 480 Joules of work with 20 watts of power would be 480 J / 20 W = 24 seconds.
What is the time taken by a body to perform 440 Joules of work at rate of 11 watt?
To calculate the time taken to perform 440 Joules of work at a rate of 11 Watts, you can use the formula: time = work / power. Plugging in the values, the time taken would be 40 seconds.
How much power is a 150 joules?
Power is the rate at which energy is transferred or converted. If 150 joules of energy is transferred in 3 seconds, the power would be 50 watts (150 joules / 3 seconds).
What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
