Power can be define as what
2 answers:
An exponent
For example the power in is the 2. It is how many times the 5 is multiplying itself. In this case 5 would multiply itself 2 times.
So... not 5 x 2, but 5 x 5
<h2>Answer</h2>
It is the rate of doing work
<h2>Explanation</h2>Power can be defined as the ability to influence the behavior of others and resist unwanted influence in return.
In physics, power is rate of doing work, or it’s the amount of energy transferred per unit time. Power is a scalar quantity mean a specific direction is not required for it.
Being the rate of work, the equation for power can be written:
For example
You are running upstair, you are applying force to cover some distance in specific time

Explanation:
We will assume that the rim of the wheel is also very thin, like the spokes. The distance <em>s</em><em> </em><em> </em>between the spokes along the rim is
The 20-cm arrow, traveling at 6 m/s, will travel its length in
The fastest speed that the wheel can spin without clipping the arrow is
The angular velocity of the wheel is given by
In terms of rev/s, we can convert the answer above as follows:
As you probably noticed, I did the calculations based on the assumption that I'm aiming for the edge of the wheel because this is the part of the wheel where a point travels a longer linear distance compared to ones closer to the axle, thus giving the arrow a better chance to pass through the wheel without getting clipped by the spokes. If you aim closer to the axle, then the wheel needs to spin slower to allow the arrow to get through without hitting the spokes.
