NOTE: Check your formula sheet if you have one these are often there.
Ac =

= rω^2
We know r = 4.00m
but what is ω?
ω =

= 2π*f
f is our frequency. we want it in seconds so we can divide by 60.
300/60 = 5rev/s
Ac = rω^2 = (4)(5)^2 = 100m/s
(b) Linear speed or v is equal to v = ω = (5)(4) = 20m/s
340 / 20 = 17
The speed of sound is 17 times faster.
NOTE: finished physics so i might be rusty and use an equation wrong. Tell me if something doesnt make sense. Im still new to this myself.

Explanation:
Found answer on another brainly post :)
Thread is to cloth as hair is to braid. Because thread is used to weave the cloth, and hair is used to weave the braid.
The purpose of sending troops to Vietnam was to prevent Vietnam from becoming a communist state- much like the neighbouring China did. The US feared the domino effect in which more and more neighbouring states become communist.
This policy was called the containment policy (the answer is B) - communism were to be contained.
