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 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 many watts does 2400 joules equal?
watts is a unit of power. joule is a unit of energy. The relationship between energy and power is: Power = Energy / Time. And 1 watt = 1 joule / second So you need to know how much time it took to deliver/transfer that 2400 joules of energy. If for example it took 1 sec, then you have 2400 w. If it took 1 minute (60 sec) Then Power = 2400 J / 60 sec = 40 w
How do you calculate data transfer rate for disk drive?
Dear...users,Actually HDD speed how to calculate means ....Use of RPM( Rate+Per+Minute)
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 work does a battery connected to a 21 ohm resistor perform in one minute?
That completely depends on the voltage of the battery.The energy delivered by the battery and dissipated by the resistor in one minute will be[ 60 x (Voltage of the battery)2 / 21 ] joules
What kind of data transfer speeds does the ION TAPE2PC USB Cassette Deck have?
It has basic tape transfer speed which is minute for song, minute for transfer.
How to calculate heat produced in the resistance?
It takes approximately 4.184 Joules of heat to raise the temperature of 1 gram of water 1 degree C. 1 Joule is the energy of 1 Watt for 1 second (or 3,600,000 Joules equals 1 Kilowatt-hour). In more real world numbers: It takes 69.7 watts 1 minute to heat a liter of water 1 degree C; or 146.6 watts in 1 minute to heat a gallon of water 1 degree F. A watt is a watt, weather it comes from resistance, radiant or induction. The only variations will come from the efficientcy of the heat source's design and how it is being used.
How much energy will a 1000w stereo use in 1 minute?
energy = power x time.In this case, you can either: * Convert the time to seconds, then multiply. The answer will be in watt-seconds = joules. * Convert the time to hours, convert the watt to kilowatt, then multiply. The answer will be in kilowatt-hours.

Briefly explain where the energy comes from in a one-minute sustained muscle contraction?
During a sustained one-minute muscle contraction, the first 4-6 seconds of energy comes from stored ATP. The next 6-15 seconds of energy comes from the transfer of creatine phosphate and ADP to form additional ATP. The last 15-60 seconds of energy comes from glycolysis.
How is Ionization energy is typically measured in units called?
The SI unit of energy is "Joules", although you could theoretically use "calories" or "Calories". However, usually due to the minute nature of atoms, I'm guessing that EV (electron volt being 1.6*10^-19 of a Joule) is more appropriate BTW, the basic unit of energy is Mass times distance squared over time squared.
What is a measure of how much work can be done in a certain amount of time?
Power = rate at which Work is done (Work or Energy divided by Time) Units often used for this include: Watt (joules/sec) Horsepower Foot-pounds/minute
