1Watt = 1 J/sec
Therefore: 100 J/sec * 10 sec = 1000J
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 = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
To calculate the energy used by a 60-watt light bulb in joules, you need to convert the power (watts) to energy (joules). First, convert watts to joules per second (1 watt = 1 joule/second), then multiply by the time the light bulb is on. So, for example, if the light bulb is on for 1 hour (3600 seconds), the energy used would be 60 watts * 3600 seconds = 216,000 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.
3000 joules(J)
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
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.)
newton-meters watt-seconds
In 2 seconds, a 100 Watt light bulb consumes 200 Joules of electrical energy from the electrical supply (100 Watts * 2 seconds = 200 Joules).
Four Hundred Joules
The energy is 95 x 40 watt-seconds (Joules).
Work is measured in joules or in watt-seconds, or equivalent units.
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 = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
To calculate the energy used by a 60-watt light bulb in joules, you need to convert the power (watts) to energy (joules).

So, for example, if the light bulb is on for 1 hour (3600 seconds), the energy used would be 60 watts * 3600 seconds = 216,000 joules.
To convert Watt seconds to milliwatt seconds, you can multiply the value in Watt seconds by 1000. This is because 1 Watt is equal to 1000 milliwatts. So, 1 Watt second is equal to 1000 milliwatt seconds.
To convert Watt seconds to milliwatts seconds, you need to multiply by 1000 since there are 1000 milliwatts in a Watt. For example, if you have 5 Watt seconds, it would be equal to 5000 milliwatts seconds.
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.
