Power is defined as the rate at which work is done, and it is calculated by dividing the amount of work done by the time it takes to do that work. In this case, if you do 1000 joules of work in 5 seconds, your power output would be 200 watts (1000 joules / 5 seconds = 200 watts). This means you are exerting a power of 200 watts to perform the work.
No, as the time required for a person to do work increases, their power output decreases. Power is defined as the amount of work done per unit of time, so the longer it takes to do work, the lower the power output.
Your power output would be 100 Watts. This can be calculated by dividing the work done (force x distance) by the time taken to do the work (10 seconds).
You simply divide 690 by 30.Your final answer is 23 seconds.
To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.
An automatic washing machine is an output device, as it takes in input in the form of water, detergent, and clothing, and produces the output of clean clothes.
Power output is calculated by dividing the work done by the time taken to do that work. In this case, work done is equal to force multiplied by distance, which is mass multiplied by acceleration due to gravity multiplied by distance. Given that the person takes 5 seconds to move 10 meters, we can calculate the speed at which they are moving. Once we have the speed, we can determine the power output using the formula for power, which is work done divided by time.
No, as the time required for a person to do work increases, their power output decreases. Power is defined as the amount of work done per unit of time, so the longer it takes to do work, the lower the power output.
Your power output would be 100 Watts. This can be calculated by dividing the work done (force x distance) by the time taken to do the work (10 seconds).
1 How many windmills it takes to power a city depends on the amount and reliability of the wind, the power output of each windmill, and the power requirements of the city.
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
The answer depends on what form the output takes.
two watts a second
Takes her 60 seconds to do what? Travel 1 mile? Travel 10 miles?
If it takes 3400J to lift a rock onto a ledge, what power is required to lift the rock onto the ledge in 4 seconds Power is energy per unit time. It is measured in watts (joules per second). As such if 3400 joules is transfeered in 4 seconds, the power equals 3400 / 4. The power required is therefore 850 watts.
14 Seconds
because of high output drive,easy to manufacture and takes less space and also low power consumption...
