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.


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 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 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.


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


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.


How long does it take to do 278 joules of work with 17 watts?

To calculate the time it takes to do 278 joules of work with 17 watts, divide the work (278 J) by the power (17 W). This gives you approximately 16.35 seconds. So, it would take about 16.35 seconds to do 278 joules of work with a power of 17 watts.


How long would it take a machie to do 5000 joules of work if the power rating of the machine is 100 watts?

To calculate the time taken to do 5000 joules of work with a 100-watt machine, you can use the formula: time (seconds) = work (joules) / power (watts). Therefore, the time taken would be 5000 joules / 100 watts, which equals 50 seconds for the machine to complete the work.


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.


Cardioversion of 200 joules - how many watts?

To calculate the power in watts, simply divide the energy in joules by the time taken to deliver that energy. If 200 joules of energy are delivered in 0.2 seconds during cardioversion, the power would be 200 Joules / 0.2 seconds = 1000 watts.


How do you find how much energy is transferred in an hour joules?

To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).


How long does it take to do 432 joules of work with 75 watts of power?

To calculate the time taken to do 432 joules of work with a power of 75 watts, you would use the formula: time = work / power. Plugging in the values gives you time = 432 Joules / 75 watts = 5.76 seconds.
