What is the change in the internal energy of a system that does 400 joules of work and absorbs 700 joules of heat?
400 joules.
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 generated by 100 Joules of work over a 10 second period?
100 watts
How much electrical energy in joules does a nuclear power reactor generate in one day?
A typical nuclear plant can run continously at 600 MW, which 6 x 108 Joules per second or, per day, 5.184 x 1013 Joules.
If you do 900 joules of work in 10 minuteshow much power have you used?
10 joules of work in 1 second
What is the average energy transfer of a TV in joules?
If you look at your television set's nameplate, it will specify its power in watts. A watt is simply a joule per second. So, if your television is rated at, say, 300 W, then it is transferring energy at the rate of 300 joules per second.
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 change in the internal energy of a system that does 400 joules of work and absorbs 700 joules of heat?
400 joules.
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 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.
What is the between work and power?
Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.
How much energy is needed to heat 50 liters of water to 50 degree centigrade?
300 calories, which is equal to about 1255.2 joules
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 work is required to pull a sled 5 meters if you use 60n of force?
Work = (Force) x (Distance) = 60 x 5= 300 Newton Meters = 300 Joules
What is the power rating of lights?
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
