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 do you calculate the minute ventilation?

What is the math formula to calculate feet per minute?
miles per hour x 88 = feet per minute
How many watts does 2400 joules equal?
To convert joules to watts, you need to know the time over which the energy is expended. Watts are a unit of power, which is energy per unit time. If the time is known, you can use the formula: Watts = Joules / seconds.
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 is involved if 1800 joules of work are done in 1 minute?
The power involved would be 30 watts. This can be calculated by dividing the work done (1800 J) by the time taken (1 minute = 60 seconds).
How many joules of heat does a 100 watt heater produce if it is operated for 5 minutes?
Based on the formula, P = E/T , and 5 min is 300 seconds, 100 = E/300, E = 30000
How much power in units of horsepower is generated from 79.3 Joules of work done in 37.2 minutes?
First, convert 37.2 minutes to seconds (37.2 minutes x 60 seconds/minute = 2232 seconds). Then calculate power using the formula Power = Work / Time. So, Power = 79.3 Joules / 2232 seconds = 0.0355 Watts. Finally, convert Watts to horsepower (1 horsepower = 746 Watts), so 0.0355 Watts = 0.0000476 horsepower.
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 many Joules do you use by walking?
The energy expenditure for walking depends on factors like speed, weight, and distance traveled. On average, a person uses about 0.2 to 0.3 calories per kilogram of body weight per minute when walking at a moderate pace. This can be converted to approximately 0.84 to 1.26 Joules per kilogram of body weight per minute.
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.

What are joules?
Joules are a unit of measurement for energy. It is often used to quantify work or energy transfer in various fields such as physics and engineering. Symbolized as J, one joule is equivalent to the energy transferred when applying a force of one newton over a distance of one meter.
