Does 200 joules of work done in 20 seconds involve more power than 50 joules of work done?
Yes, because power is a measure of how quickly work is done. In this case, the power for the 200 joules of work done in 20 seconds would be 10 watts, while the power for the 50 joules of work done would be 2.5 watts. Hence, 200 joules of work done involves more power than 50 joules of work done.
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.
Are watts measured by Joules divided by meters or Joules divided by seconds?
Watts are measured by Joules divided by seconds. The watt is the unit of power, representing the rate at which energy is transferred. It is calculated by dividing the energy (measured in Joules) by the time (measured in seconds) over which the energy is transferred.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
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.
Does 200 joules of work done in 20 seconds involve more power than 50 joules of work done?
Yes, because power is a measure of how quickly work is done. In this case, the power for the 200 joules of work done in 20 seconds would be 10 watts, while the power for the 50 joules of work done would be 2.5 watts. Hence, 200 joules of work done involves more power than 50 joules of work done.
What is joules divided by seconds?
watts
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
What is the power output of an engine that does 60 000 joules of work in 10 seconds?
60,000 joules per 10 seconds = 6,000 joules per second = 6,000 watts
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.
Are watts measured by Joules divided by meters or Joules divided by seconds?
Watts are measured by Joules divided by seconds. The watt is the unit of power, representing the rate at which energy is transferred. It is calculated by dividing the energy (measured in Joules) by the time (measured in seconds) over which the energy is transferred.
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 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 many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
How much power in watts is needed to cut a lawn in 50 min if the work involves is 100000?
well then all you have to do is divide here i have a sort out just for you an examplepower (in watts) = work divided by timeor for you smart ones:power=joules divided by time or sec.Following the above:Power (in watts) * time (seconds) = joules100,000 joules = 100,000 watt / seconds => (100,000 Watt / seconds ) * (50 minutes, or 3000 seconds) = 33.3 watts.
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 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.
