Work (energy transferred) = force x distance = 200 N x 10 m = 2000 Joule.
Power = work / time = 2000 Joules / 8 seconds = 250 Watts.
First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
An arachnologist works with arachnid or spiders. A bachelor's degree in biology is required and takes four years to complete.
What a number is raised to. Three (the base) to the third power = 33 = 3*3*3 The power or the exponent tells us how many times the base takes place in a repeated multiplication.
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.
To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.
10 seconds
First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
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.
The power required to lift the rock onto the ledge can be calculated as work done divided by time. In this case, it is 3400J / 4s = 850 watts. Therefore, 850 watts of power is required to lift the rock onto the ledge in 4 seconds.
The more load that is put on the alternator the more power is required to drive it. This is an interesting question and I really do not have the exact number. But I do know from spinning an alternator with my hand that is takes very little power to turn it when it is not connected to anything. But connect it to a battery that is dead and it takes some power to spin it. I would estimate it takes from 2-3 hp depending on the load. #2 Approximately 1 HP is required to drive an alternator for every 746 watts of electrical power it produces. In practice 1 HP of mechanical power produces a little less than 746 watts at the output because of frictional and resistive losses.

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.

The person who takes power illegaly in Greece is the tyrant!
It has low resistance so takes more current.. hence the power
yes it is. oxygen and glucose are both required.
Born into power, marries into power, takes power by force.
