What is A to the second power plus a to the second power?
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
250 watts is how many amps?
Depends on the voltage. AMPS X VOLTS = WATTS 250 Watts at 12 V would be about 21 Amps, while 250 watts at 120 volts would be 2.1 amps.
What does 35 to the second power mean?
the second power means you multiply the number by itself. 32 to the second power would be 32*32. 32 to the third power would be 32*32*32
Negative 5 to the second power equals?
Negative 5 to the second power would be -5 times -5 which would be 25.
A triangle has a height of 4 ft and an area 32 ft to the second power . what is the length of its base?
the length of the base would be 16
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
Do 100 joules of work in 50 seconds and your power output is?
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
What is the nit to measure the energy or intensity of sound?
Energy: joulesPerhaps you mean power: that would be joules/second = watts Intensity is measured in watts per square meter.
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 does a toaster have if it does 21000 joules of work in 30 seconds?
Efficiency here would be power out divided by power in. Energy out is 38,000 Joules. A joule is a watt X second. The toaster is on for 120 seconds. So that 316.66... watts power over the time period t(which doesn't matter). 316.66... watts/ 330 watts = 0.95959.... efficient or 96%.
491600.6 watts of energy?
Is it not....... energy = watts x seconds so assuming this is only over the period of 1 second it would be 491600.6 joules.....
What is the unit of thermal resistance?
Thermal resistance is the resistance of a substance or material to the conduction of thermal energy, or heat. For stuff at the high end of the scale, that is, for stuff having a whole lot of thermal resistance, we might use the term thermal insulator.
How do you convert Mega Joules to Joules?
You can't convert them directly, because they measure different things. The unit for energy is the Joule. Power means how fast energy is transferred; it is measured in Joules/second, also called Watts.
How much power in watts is needed to cut a lawn in 50 min?
well then all you have to do is divide here i have a sort out just for you an examplepower (in watts) = work divided by timeor for you smart ones:power=joules divided by time or sec.Following the above:Power (in watts) * time (seconds) = joules100,000 joules = 100,000 watt / seconds => (100,000 Watt / seconds ) * (50 minutes, or 3000 seconds) = 33.3 watts.
Is work labeled in joules?
Yes.Joules also refer to work as a measurement of power necessary during a time. One amp through a one-ohm resistance for one second would convert 1 joule of energy to heat.For example: a watt requires one joule per second. If there were 50 joules used in that second, it would be 50 watts of power.Power measured in watts can be converted to other dimensions of work, such as horsepower, Btu/hr, dBm, tons of refrigeration, etc.
How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second
Power is the ability to?
Power is work per time, joules per second. So Power would be the rate at which work can be performed.
