How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
How many kilocaclories of heat does the operation of a 1190 watt hair dryer produces each second?
Watts means joules per second. The device uses 1190 joules of energy every second; most of that will be converted to heat. It is best to use SI units most of the time; in this case, joules rather than calories for energy. However, if you want to convert that, 1 calorie = 4.184 joules; thus, you can divide the number of joules by 4.184 to convert it to calories.
How much work is done when a 70kg person climbs a ladder meters tall?
At least 3,500 joules, if his climbing effort is 100% efficient, but probably more than that.
What is joules in science?
joules are the amount of energy
How many joules are in 55.2 calories?
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
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.
Which month has the least tornado activity?
December generally has the least tornado activity.
Are joules small or large?
You decide that for yourself, whether you consider it small or large. To give you an idea, watt means joules/second, so a 40-watt light bulb uses 40 joules every second.
What is the least amount of mercury that can be vaporized when 3 million joules are introduced?
10kg
When was the solar activity the least?
The least known amount of solar activity occurred in the year 1871.
When was the least amount of solar activity?
The least known amount of solar activity occurred in the year 1871.

What Uses a browser to perform email activity?

What activity in the US uses the most water?
Industry.
How many joules are in 56 kilo joules?
56 kilo joules = 56,000 joules
How do you convert kilojoules into calories?
Depends on the type of calorie you're asking about. A "small calorie" which uses the symbol 'cal' is equivalent to about 4.18 Joules. A "large calorie" which uses the symbol 'Cal' is equivalent to about 4.18 Kilo Joules.
