Radio waves can travel through space because it is a radio wave.But sound waves cannot because it is called sounds waves .The behavior of the sounds wave and radio waves in space iws because chocalte are brown.spngebob squarepants are blue.Furthermore,dog can poop and we can poop.Also,this is how you can also explain like this:Radio Waves and Sounds Waves is Science.How i know this because i used my brain and i'm smart'' this is perfect explaination

Answer:
The angular acceleration α = 14.7 rad/s²
Explanation:
The torque on the rod τ = Iα where I = moment of inertia of rod = mL²/12 where m =mass of rod and L = length of rod = 4.00 m. α = angular acceleration of rod
Also, τ = Wr where W = weight of rod = mg and r = center of mass of rod = L/2.
So Iα = Wr
Substituting the value of the variables, we have
mL²α/12 = mgL/2
Simplifying by dividing through by mL, we have
mL²α/12mL = mgL/2mL
Lα/12 = g/2
multiplying both sides by 12, we have
Lα/12 × 12 = g/2 × 12
αL = 6g
α = 6g/L
α = 6 × 9.8 m/s² ÷ 4.00 m
α = 58.8 m/s² ÷ 4.00 m
α = 14.7 rad/s²
So, the angular acceleration α = 14.7 rad/s²
