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.
The person's speed is 2 meters per second. The power required for him to accomplish that depends on his weight, on his efficiency of movement, on whether he's moving horizontally or vertically, etc., all of which the question neglects to specify.
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.
An arachnologist works with arachnid or spiders. A bachelor's degree in biology is required and takes four years to complete.
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
power is required to do work and work efficiancy is the ammount of time it takes to do work.
First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
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.
300 W
300 W
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.
The person who takes power illegaly in Greece is the tyrant!
It has low resistance so takes more current.. hence the power
In a nuclear power plant, fission takes place in the core.
yes it is. oxygen and glucose are both required.
Born into power, marries into power, takes power by force.
