183.33... Watts.
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
By heating it or compressing it.
Calculate this in two steps. 1. Calculate the total work required. Reminder: work = force x distance. 2. Divide the work by the time to get the power.
If you do work on an object in half the your power output is
power is a rate of energy transfer. given enough time, any positive amount of power could do this.
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
The idea is to divide the work by the time.
By heating it or compressing it.
Calculate this in two steps. 1. Calculate the total work required. Reminder: work = force x distance. 2. Divide the work by the time to get the power.
Kilowatss (kw) are a measure of power, not speed. The speed of an object with 8.2 kw of power applied to it is dependent on the mass of the object, the acceleration time, and any resistive friction forces.
If you do work on an object in half the your power output is
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 a rate of energy transfer. given enough time, any positive amount of power could do this.
Since power is defined as Work divided by time, and work is F x d. W = 110 x 20 W = 2200 J P = 2200 / 8 = 275 Watts
Time required to do what? To move from one place to another, divide the distance by the speed of light.
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
As power = work done/time, power depends upon magnitude of w.d. and time required.
