Answer:
The reaction force from the shaft, which keeps the wheels in place during operational rotation
Explanation:
The pinwheel design which has the same principle of a turbine, relies on a external energy source such as the wind or water to provide motive force for spinning
Whereby the reaction force provided by the shaft holding the wheel is non existent or insufficient, the wind will be able to push the wheel in its direction thereby giving the wheel only a net translation and no rotation.
<span>An increase in voltage causes the flow of electric current to increase.
Voltage and flow of electric current are <em>directly related</em>, so when the voltage increases, the flow of electric current increases, as well.
If the voltage were to decrease, the flow of electric current would decrease, too.

If there is no difference in the dry and wet bulb temperatures,
you can assume that the relative humidity is 100% . . . since
no water was able to evaporate from the wet bulb.
Answer:
= -8πx
Explanation:
If you need calculate
You can use the Ampere's Law
= μ
Where : Current passing through the window
μ : Free space’s magnetic permeability
μ = 4πx
Then
= (3-5)4πx
= -8πx
Answer:
No,
Explanation:
An electromagnetic wave is made of vibrating electric and magnetic fields that continually induce each other; matter is not needed for this to occur.
