Does 200 joules of work done in 20 seconds involve more power than 50 joules of work done?
Yes, because power is a measure of how quickly work is done. In this case, the power for the 200 joules of work done in 20 seconds would be 10 watts, while the power for the 50 joules of work done would be 2.5 watts. Hence, 200 joules of work done involves more power than 50 joules of work done.
What else can I help you with?
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 when 600 joules of work are done in ten seconds?
The power used would be 60 watts. This can be calculated by dividing the work done (600 joules) by the time taken (10 seconds).
What is 10 joules of work in 20 seconds?
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
What is the power of a machine that does 1500 joules of work in 30 seconds?
The power of the machine is 50 watts. Power is calculated by dividing the work done (1500 joules) by the time taken to do the work (30 seconds).
How much power is necessary to do 50 joules of work in 5 seconds?
The power required to do 50 joules of work in 5 seconds is 10 watts. This is calculated by dividing the work done (50 joules) by the time taken (5 seconds), which equals 10 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 when 600 joules of work are done in ten seconds?
The power used would be 60 watts. This can be calculated by dividing the work done (600 joules) by the time taken (10 seconds).
What is 10 joules of work in 20 seconds?
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
What is the power of a machine that does 1500 joules of work in 30 seconds?
The power of the machine is 50 watts. Power is calculated by dividing the work done (1500 joules) by the time taken to do the work (30 seconds).
How much power is necessary to do 50 joules of work in 5 seconds?
The power required to do 50 joules of work in 5 seconds is 10 watts. This is calculated by dividing the work done (50 joules) by the time taken (5 seconds), which equals 10 watts.
How much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
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.
If a person exerts 100 watts of power in 10 seconds. How much work was done?
If a human adult uses energy athe rate of 100 watts, or 100 joules per second, and sustains this rate for 10 seconds, the work done equals 1 kilojoule.
If 600 watts of power are used in 45 seconds how much work was done?
The work done can be calculated using the formula: Work = Power x Time. Plugging in the values, we get Work = 600 watts x 45 seconds = 27,000 joules. Therefore, 27,000 joules of work was done.
How much work was done if 550 watts of power are used in 55 seconds?
The work done can be calculated using the formula: Work = Power x Time Substitute the given values: Work = 550 watts x 55 seconds Work = 30250 joules So, 30250 joules of work was done.
How much power is necessary to do 20 joules of work in 2 second?
The power required to do 20 joules of work in 2 seconds is 10 watts. This is calculated by dividing the work done (20 joules) by the time taken (2 seconds). Therefore, the power = Work / Time = 20 J / 2 s = 10 W.
