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.

How long does it take to perform 450 Joules of work with 25 watts of power?
18 Seconds (:
How long does it take to perform 480 Joules of work with 20 watts of power?
480 joules = 480 watt-seconds20 watts x (time) = 480 watt-secondsDivide each side by 20 watts:Time = 24 seconds
How much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
How much power does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
How many joules of work can a quarter - horsepower air conditioning unit perform in ten minutes?
Convert to compatible units: convert horse-power to watts, and minutes to seconds. Then use the formula: work = power x time.
How much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
How long does it take to perform 450 Joules of work with 25 watts of power?
18 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
How much power is needed to perform 900 Joules of work in 90 seconds?
Power is energy per unit time. So, the required power is 900/90 = 10 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.
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
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.
How long does it take to perform 480 Joules of work with 20 watts of power?
480 joules = 480 watt-seconds20 watts x (time) = 480 watt-secondsDivide each side by 20 watts:Time = 24 seconds
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 much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
How much power does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
