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 units of horsepower is generated from 79.3 Joules of work done in 37.2 minutes?
Power = energy/timeWatts = joules/seconds(79.3 joules/37.2 minutes) x (minute/60 seconds) = 0.03553 watt= 35.53 mW = +15.5 dBm (rounded)====================To answer the question:(79.3 joules/37.2 minutes) x (minute/60 seconds) x (horsepower/745.7 watts) = 0.0000476 HP (rounded)47.6 microhorsepower(power output of 47.6 microhorses)
How much power does a toaster have if it does 21000 joules of work in 30 seconds?
Efficiency here would be power out divided by power in. Energy out is 38,000 Joules. A joule is a watt X second. The toaster is on for 120 seconds. So that 316.66... watts power over the time period t(which doesn't matter). 316.66... watts/ 330 watts = 0.95959.... efficient or 96%.
What does power equal?
Power = Work divided by seconds.or in other words....Power = work/seconds.Clear explanation: Power is equal to:How much work is done (in joules) divided by the seconds of how much time did the work took.For example:Problem: A construction worker pushes the wheelbarrow with the power of 50 J per 2 seconds how much power does he use?Answer: 50 J divided by 2 s is 25 W so, the power is equal to 25 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 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 is needed to perform 600 Joules of work in 120 seconds?
7.5 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.
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
How much power is used when 600J of work are done in 10s?
60 W
How much power in units of horsepower is generated from 79.3 Joules of work done in 37.2 minutes?
Power = energy/timeWatts = joules/seconds(79.3 joules/37.2 minutes) x (minute/60 seconds) = 0.03553 watt= 35.53 mW = +15.5 dBm (rounded)====================To answer the question:(79.3 joules/37.2 minutes) x (minute/60 seconds) x (horsepower/745.7 watts) = 0.0000476 HP (rounded)47.6 microhorsepower(power output of 47.6 microhorses)
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 work can a 500 watt electric mixer do in 2.50 minutes?
The work or energy in Joules is the power in watts times the number of second it runs for. So 500 watts for 150 seconds is 75,000 Joules.
How much work is done using a 60-watt light bulb for 1 hour?
In terms of joules, the answer is 216,000 joules. First, you must convert 1 hour to seconds. 1 hr = 60 mins 60 mins = 3,600 seconds The formula for finding power can also be used to find work if power and time are provided. Power = Work/Time 60 watts =work/3,600 seconds To find this, multiply 3,600 by 60 3,600 X 60 = 216,000 The unit for work is joules, so the answer is 216,000 joules.use the power formula
