What is the power of 50 joules in 5 seconds?
Power = energy/time = 50/5 = 10 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 much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
What is the power out put of one million joules?
A joule is a unit of energy, not a unit of power. A watt is the same as a joule per second, so depending on how long it takes to output a million joules, the power can be very high, or very low.
What amount of work can a 600 W motor do in 4 minutes?
(600 Watts) x (4 minutes) = (600 joules per second) x (240 seconds) = 144,000 joules =144 kilojoules
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.
Do 100 joules of work in 50 seconds and your power output is?
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
How much power in watts could you get out of the turbine with a potential energy of 19600 joules if it were perfectly efficient?
If the turbine were perfectly efficient, all of the potential energy of 19600 joules would be converted into mechanical energy. To convert this to power output in watts, you would divide the energy by the time taken for the conversion to occur. If the conversion happened in 10 seconds, the power output would be 1960 watts (19600 joules / 10 seconds).
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
If it takes 5 seconds for you to do 1000j of work's what is your power output?
Power is defined as the rate at which work is done, and it is calculated by dividing the amount of work done by the time it takes to do that work. In this case, if you do 1000 joules of work in 5 seconds, your power output would be 200 watts (1000 joules / 5 seconds = 200 watts). This means you are exerting a power of 200 watts to perform 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.
How much power in units of horsepower is generated from 79.3 Joules of work done in 37.2 minutes?
First, convert 37.2 minutes to seconds (37.2 minutes x 60 seconds/minute = 2232 seconds). Then calculate power using the formula Power = Work / Time. So, Power = 79.3 Joules / 2232 seconds = 0.0355 Watts. Finally, convert Watts to horsepower (1 horsepower = 746 Watts), so 0.0355 Watts = 0.0000476 horsepower.
A power station produces electricity with an output power of 200MW at a voltage of 25000V Calculate the energy output in 1 day of operation?
Multiply 200 MW by the amount of time (in seconds) that the plant runs (86400 seconds in a day). This gives 1.728 * 10^16 Joules in a single day.
How much power is necessary to do 50 joules of work in 5 seconds?
The power required to do 50 joules of work in 5 seconds is 10 watts. This is calculated by dividing the work done (50 joules) by the time taken (5 seconds), which equals 10 watts.
What is the power of a machine that does 1500 joules of work in 30 seconds?
The power of the machine is 50 watts. Power is calculated by dividing the work done (1500 joules) by the time taken to do the work (30 seconds).
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.
