Answer:
The correct option is;
- 4x
Explanation:
From the inverse square law, as the distance from the source of a physical quantity increases, the intensity of the source is spread over an area proportional to the square of the distance of the object from the source
The inverse square law can be presented as follows;
As the distance, r, increases, the surface it covers also increases by the power of 2
Therefore, where the distance increases from r to 2·r, we have;
When, I, remain constant
The surface increases to 4·S by the inverse square law
Therefore, the correct option is 4 × x.
The frequency of the wheel is the number of revolutions per second:
And now we can calculate the angular speed, which is given by:
in the clockwise direction.
And now we can calculate the angular speed, which is given by:
