You can't calculate the force from the rate at which work is done.
10 joules in 20 seconds could be:
-- 1 newton pushing along at 50 centimeters per second, or
-- 0.1 newton pushing 5 meters per second, or
an infinite number of other possibilities.
From the data given in the question, all we know is that the 'power' is 1/2 watt.
Power is equal to work done divided by time, where work done is force multiplied by distance. In this case, the work done is 100 newtons * 10 meters = 1000 joules. Therefore, the power used would be 1000 joules / 5 seconds = 200 watts.
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.
To calculate the energy in joules, we need more information such as the distance over which the force is applied. If we assume the force is applied over a distance of 1 meter, then the work done would be 10 joules (Work = Force x Distance).
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.
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
Four Hundred Joules
Power is equal to work done divided by time, where work done is force multiplied by distance. In this case, the work done is 100 newtons * 10 meters = 1000 joules. Therefore, the power used would be 1000 joules / 5 seconds = 200 watts.
Work done is calculated using the formula ( \text{Work} = \text{Force} \times \text{Distance} ). In this case, with a force of 2 newtons over a distance of 10 meters, the work done is ( 2 , \text{N} \times 10 , \text{m} = 20 , \text{joules} ). Therefore, 2 newtons through 10 meters equals 20 joules.
60,000 joules per 10 seconds = 6,000 joules per second = 6,000 watts
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.
To calculate the energy in joules, we need more information such as the distance over which the force is applied. If we assume the force is applied over a distance of 1 meter, then the work done would be 10 joules (Work = Force x Distance).
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.
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
Work = Force x Distance. The answer is 10 joules.
Power is calculated as energy consumed per unit time. If a bulb uses 3 joules of energy every 10 seconds, its power can be calculated using the formula: Power (in watts) = Energy (in joules) / Time (in seconds). Therefore, the power of the bulb is 3 joules / 10 seconds = 0.3 watts.
