How many seconds does it take for a 100 Watt bulb to transform 120 Joules of energy?
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.

How long could 90 Js of energy light a 40 Watt light balb.?
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.
60-watt light bulb in jouls?
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.
How much electrical energy in joules does a 100 watt lamp transfer in 1 minute?
A 100 watt lamp transfers energy at a rate of 100 joules per second. Over the course of 1 minute (which is 60 seconds), the total energy transferred can be calculated by multiplying the power by the time: 100 watts × 60 seconds = 6000 joules. Therefore, a 100 watt lamp transfers 6000 joules of electrical energy in 1 minute.
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
How much energy does a 100-w light bulb use in 20 s?
A 100-watt light bulb uses 100 watts of power, which is equivalent to 100 joules per second. Therefore, in 20 seconds, it would consume energy calculated as follows: 100 watts × 20 seconds = 2000 joules. Thus, a 100-watt light bulb uses 2000 joules of energy in 20 seconds.
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).

Are watts measured by Joules divided by meters or Joules divided by seconds?
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.
