Answer:
Distance from the jackhammer is given as
where I is intensity at x = 4 m
Explanation:
As we know that the loudness of the sound is given as
So we have
we have to change the intensity becomes
so the loudness becomes 1/8 times of initial
now we know that intensity inversely varies with the square of the distance
so we have
so we have

Answer:
0.12m/s
Explanation:
v=λf
Given that, λ = 12cm = 0.12m
T = 1second
(A period T is the time required for one complete cycle of vibration to pass a given point)
frequency 'f' is unknown but we can get frequency from f = 1/T = 1/1 = 1Hz
therefore, v= 0.12 × 1 = 0.12m/s
