To find the time it takes for a 100 Watt bulb to transform 120 Joules of energy, you can use the formula: power (Watts) = energy (Joules) / time (seconds). Rearranging the formula gives time = energy / power. Thus, time = 120 Joules / 100 Watts = 1.2 seconds. Therefore, it takes 1.2 seconds for the bulb to transform 120 Joules of energy.
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.
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
The energy transferred by a 100 Watt bulb in 10 seconds can be calculated using the formula: Energy (joules) = Power (Watts) x Time (seconds). Plugging in the values, the calculation would be 100 Watts x 10 seconds = 1000 joules.
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
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).
The energy is 95 x 40 watt-seconds (Joules).
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.
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
Watts are measured by Joules divided by seconds. The watt is the unit of power, representing the rate at which energy is transferred. It is calculated by dividing the energy (measured in Joules) by the time (measured in seconds) over which the energy is transferred.
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

The energy transferred by a 100 Watt bulb in 10 seconds can be calculated using the formula: Energy (joules) = Power (Watts) x Time (seconds). Plugging in the values, the calculation would be 100 Watts x 10 seconds = 1000 joules.

1 Watt means 1 Joule per second, so 60 watts means 60 Joules per second. A light bulb that burns energy at that rate for 3 seconds uses 180 Joules.
1 watt-second = 1 joule...746 watt-seconds = 746 joules(746 watts is an interesting number, and I'm curious to know how it wasselected to be the number in the question. 746 watts = 1 horsepower.1 horsepower = 746 joules of energy per second.The number is easy to remember: The mainsail on the Santa Maria developed2 HP in a fresh breeze during Christopher Columbus' first voyage in 1492.)
