How long would a 60 watt light bulb have to burn to produce the energy you used climbing the stairs?
It would depend on your weight and the height of the stairs climbed. As an estimate, a 60 Watt light bulb uses 60 Joules of energy per second. You can calculate the total energy used climbing the stairs in Joules and then divide by 60 to find the number of seconds the light bulb would have to burn.
How long willl it take to build the infrastructureto produce this energy?
Which energy?
How long could 90 Js of energy light a 40 Watt light balb.?
To calculate this, we first need to convert the energy from joules to watt-hours. 90 joules is equal to 0.025 watt-hours. Therefore, with 0.025 watt-hours of energy, a 40 watt light bulb would last for approximately 0.000625 hours or 0.0375 minutes.
What is the power out put of one million joules?
A joule is a unit of energy, not a unit of power. A watt is the same as a joule per second, so depending on how long it takes to output a million joules, the power can be very high, or very low.
How long would it take for a 60W light bulb to do 5400J of work?
60 watts = 60 joules per second5,400 joules = (5,400 / 60) = 90 seconds, at the rate of 60 wattsBut we must disagree with the language of the question.At the rate of 60 watts, it takes 90 seconds to use 5,400 joules of energy. But no work is done.The energy is converted into electromagnetic energy, in the form of heat and light, and it'scarried away from the light bulb by the E&M radiation.
Can a pinwheel produce enough energy to give to a Christmas light bulb?
No, unless you hook it up electronically then it will probably not produce enough energy to light it up as bright or as long as and outlet.
How can energy be turned into heat energy?
Depends what energy you're talking about... Kinetic energy is the easiest one... you rub it on other stuff long and hard enough and it will produce heat. Chemical energy would produce heat if you mix the right stuff together. Electrical energy will produce heat if it flows through a heating element like in your toaster. . . and so on.
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.
What is the measurement in time for 4 kilowatts?
"kilowatts" is a rate, not a time. A kilowatt is 1000 watts, or energy being transferred at 1000 joules per second. (A watt is a joule per second.) Your question means the same as this question: "What is the measurement in time for 100 forty-watt lightbulbs?" You can leave the lights on as long as you wish. Collectively, every second they will convert 4000 joules of electrical energy to light and heat energy.
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.
Why can't the two anaerobic energy systems be used to fuel long periods of exercise?
Because neither of these systems requires oxygen to produce energy
How long can you operate a 100 W bulb with 1 Joule of energy?
The light bulb dissipates 100 watts = 100 joules per second.1 joule lasts 0.01 second.
