First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
Work (energy transferred) = force x distance = 200 N x 10 m = 2000 Joule. Power = work / time = 2000 Joules / 8 seconds = 250 Watts.

As much as you like except that the force required increases as the angle increases.
Power is the rate at which work is done. To find the power required to do 100 J of work in 5 s, divide the work by the time: 100 J / 5 s = 20 watts. If the same work is done in 1 s, the power required would be 100 watts, as power is inversely proportional to time.
The power required to do 40 J of work in 5 seconds is 8 watts. This can be calculated by dividing the work (40 J) by the time (5 seconds). The formula for power is Power = Work / Time.
The power required to move the bag of books can be calculated by dividing the work done (12900 J) by the time taken (3 minutes = 180 s). So, the power required is 71.67 watts.

Power is calculated as work done divided by time taken, so power = work/time. In this case, power = 110 J / 0.6 s = 183.33 watts.
The work done in lifting the crate is equal to its change in potential energy: ( \text{Work} = \text{Force} \times \text{distance} = m \cdot g \cdot h ). The power required is the work done divided by the time taken: ( \text{Power} = \frac{\text{Work}}{\text{time}} ). Plug in the values to calculate the power required.
Power, work, and time are related through the equation Power = Work/Time. Power measures the rate at which work is done, while work is the transfer of energy that results in a change in the state of a system. Time is the duration over which work is done, influencing the power required to perform the work efficiently.
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.
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
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.
The power needed to do 50 joules of work in 5 seconds is calculated by dividing the work by the time, which equals to 10 watts. So, 10 watts of power is required to do this amount of work in the given time frame.
