How long does it take to perform 500 Joules of work with 25 watts of power?
Divide 500 by 25. The answer is 20.
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 long does it take to do 690 joules of work with 30 watts of power?
You simply divide 690 by 30.Your final answer is 23 seconds.
How long does it take to do 432 joules of work with 75 watts of power?
A watt is equal to 1 Joule per second. So 432 Joules * (1 / 75 Joules per second) = 432/75 = 5.76 seconds.
How much fossil fuel is needed to make 12Watts of electricity?
Can't be answered. 12 Watts is a measure of power, not energy - so you have to say how long you want it for. 12 watts for 10 seconds would be a quite different answer than 12 watts for one hour.
How long does it take to perform 750 Joules of work with 30 watts of power?
25 sec.
How long does it take to perform 500 Joules of work with 25 watts of power?
Divide 500 by 25. The answer is 20.
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 long could 90 Js of energy light a 40 Watt light balb.?
Power (watts) = Energy (joules) / time (seconds). Thus, Time (seconds) = Energy (joules) / Power (watts) = 90J / 40W = 2.25s
How long does it take to do 690 joules of work with 30 watts of power?
You simply divide 690 by 30.Your final answer is 23 seconds.
How you convert 36watts in joules?
Watts is a unit of power; Joules is a unit of energy. Watts means Joules/second, so you would need to know how long a machine that uses 36 watts (for example, certain light-bulbs) is used.36 watts is simply 36 Joules per second; this is the same as 2160 Joules per minute, or 129,600 Joules per hour.Since the electricity bill is measured in kWh instead of Joule (1 kWh = 3,600,000 Ws = 3,600,000 Joule), you might also say that a device that uses 36 watts uses 0.036 kWh every hour.
How many watts is needed to melt one pound of aluminum?
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
How long does it take to do 432 joules of work with 75 watts of power?
A watt is equal to 1 Joule per second. So 432 Joules * (1 / 75 Joules per second) = 432/75 = 5.76 seconds.
Nisha's vacuum cleaner has a power rating of 200 watts. If the vacuum cleaner does 360000 joules of work. How long did Nisha spend vacuuming?
Time= 1800
How many joules of energy does a 100 watt light bulb have?
No, because they measure different things. A Joule is an amount of energy, and a Watt measures how fast energy is being used. 1 Watt is equal to 1 Joule per second. So, 100 watts = 100 Joules per second.
How long is 1mega wots?
all day long it is a measure of power 100 watts is a light bulb 1,000,000 watts is a mega watt used to describe power plants or electrical substation
How much energy do you save with 10 light bulbs off?
That depends on the power used by each light bulb. Look at the specifications for a specific light bulb, then multiply the power by 10. Note that energy = power x time; that is to say, the energy spent by a light bulb depends on its power, but also on how long you keep it on. Specifically, watts = joules x seconds.
