Sound intensity = 1/(r^2)
That is Sound intensity is indirectly proportional to the distance. Therefore, sound becomes 9 times less intense.
Where are the questions so that I can deliver a more accurate answer.
Answer:
W= F × d
W= 2kn × 3.6
W= 7.2 J
Work is measured in Joules!
Answer:
Explanation:
The acceleration of a circular motion is given by
where is the angular velocity and is the radius.
Angular velocity is related to the period, T, by
Substitute into the previous formula.
This acceleration does not depend on the linear or angular displacement. Hence, the amount of rotation does not change it.
