Answer:
223.55 W
Explanation:
v = Velocity of wind = 10 m/s
r = Radius of circle = 5 m
S = Swept area
= Density of air = 1.2 kg/m³
= Power coefficient = 0.593
The maximum possible power that can be produced by the turbine is 223.55 W
One way to do it is she could right down the data that she got
A. To show how precise your measurements were
Explanation:
It is important to use the correct number of significant digits when reporting the results of an experiment because they show how precise measurement are.
- Precision is the ability to reproduce a particular set of results in an experiment.
- Every instrument have their precision level.
- The precision levels shows to what extent the values obtained can be trusted..
- Significant figures are not only important in recording measurements, they are also needed for calculations in science.

There's no physics or electronics to this question.
It's just arithmetic.
The last part of the question TELLS you how many 'coulombs per electron'.
If you just flip that fraction (divide ' 1 ' by it, take its reciprocal), then
you'll have 'electrons per coulomb', and 5 of those will answer the question.
