Answer:
The mass of the wheel is 2159.045 kg
Explanation:
Given:
Radius 
m
Force
N
Angular acceleration 
From the formula of torque,
Γ
(1)
Γ
(2)

Find momentum of inertia
from above equation,



Find the momentum inertia of disk,



Kg
Therefore, the mass of the wheel is 2159.045 kg

As per as my knowledge
The speed of a wave in a medium is affected by <u>d</u><u>e</u><u>n</u><u>s</u><u>i</u><u>t</u><u>y</u>,<u> </u><u>w</u><u>a</u><u>v</u><u>e</u><u>l</u><u>e</u><u>n</u><u>g</u><u>t</u><u>h</u> and <u>t</u><u>e</u><u>m</u><u>p</u><u>e</u><u>r</u><u>a</u><u>t</u><u>u</u><u>r</u><u>e</u><u> </u>:)
