A point source emits 25.9 W of sound isotropically. A small microphone intercepts the sound in an area of 0.242 cm2, 590 m from
the source. Calculate (a) the sound intensity there and (b) the power intercepted by the microphone.

Answer:
I = 0.0025 kg.m²
Explanation:
Given that
m= 2 kg
Diameter ,d= 0.1 m
Radius ,
R=0.05 m
The moment of inertia of the cylinder about it's axis same as the disc and it is given as
Now by putting the all values
I = 0.0025 kg.m²
Therefore we can say that the moment of inertia of the cylinder will be 0.0025 kg.m².
Answer:
average acceleration = 6
Explanation:
Recall that the average acceleration is defined by the change in velocity from an initial velocity
, to a final velocity
over the time (t) it took that change to happen. Then, in mathematical terms this is:
with our information this becomes:
