How much joules of heat does a 100 W of heater produce if it is operated for 5 min?
The amount of heat produced by the 100 W heater in 5 minutes can be calculated as follows: Power (in watts) = 100 W Time (in seconds) = 5 minutes * 60 seconds/minute = 300 seconds Energy = Power * Time = 100 W * 300 s = 30,000 joules So, the heater will produce 30,000 joules of heat.
How much power is necessary to do 60 joules of work in 20 seconds?
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
How do you find how much energy is transferred in an hour joules?
To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).
How much power is used when Joules of work are done in 10 seconds?
Power is calculated by dividing the work done in Joules by the time taken in seconds. So, if x Joules of work are done in 10 seconds, the power used would be x/10 watts.
How much power is used (in watts) when 120 joules of work is done in 1 minute?
Power is the rate at which work is done, given by the formula Power = Work/Time. In this case, Power = 120 Joules / 60 seconds = 2 Watts.
How much joules of heat does a 100 W of heater produce if it is operated for 5 min?
The amount of heat produced by the 100 W heater in 5 minutes can be calculated as follows: Power (in watts) = 100 W Time (in seconds) = 5 minutes * 60 seconds/minute = 300 seconds Energy = Power * Time = 100 W * 300 s = 30,000 joules So, the heater will produce 30,000 joules of heat.
If you do 900 joules of work in 10 minuteshow much power have you used?
10 joules of work in 1 second
How much power is necessary to do 60 joules of work in 20 seconds?
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
A blender has a power of 0.3 kW. It is used to make a fruit smoothie, which takes 50 seconds. How much energy is used Give your answer in kilojoules.kJ?
To calculate the energy used by the blender, we first convert the power from kilowatts to watts: 0.3 kW = 300 watts. Then, we use the formula Energy (in joules) = Power (in watts) x Time (in seconds). Plugging in the values, we get Energy = 300 watts x 50 seconds = 15,000 joules. Finally, to convert joules to kilojoules, we divide by 1,000: 15,000 joules ÷ 1,000 = 15 kJ. Therefore, the blender uses 15 kilojoules of energy to make the fruit smoothie.

To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).
What is the average energy transfer of a TV in joules?
If you look at your television set's nameplate, it will specify its power in watts. A watt is simply a joule per second. So, if your television is rated at, say, 300 W, then it is transferring energy at the rate of 300 joules per second.
How much power does an athlete to do 800 joules of work 5 seconds?
To calculate power, you can use the formula: Power = Work / Time. In this case, the athlete does 800 joules of work over 5 seconds. Therefore, the power output is 800 joules / 5 seconds = 160 watts.
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
How much power is used when Joules of work are done in 10 seconds?
Power is calculated by dividing the work done in Joules by the time taken in seconds. So, if x Joules of work are done in 10 seconds, the power used would be x/10 watts.
How much power is used (in watts) when 120 joules of work is done in 1 minute?
Power is the rate at which work is done, given by the formula Power = Work/Time. In this case, Power = 120 Joules / 60 seconds = 2 Watts.
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
A force of 300 N is applied to a box for 10 seconds in order to move the box 10 m. What is the power?
The work done on the box is 3000 Joules (N*m) (300 N * 10 m). Power is work done per unit time, so the power applied to the box is 300 Watts (3000J / 10 s).
