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.
Answer: 3:12 pm (C.)
Explanation:
The 4 train from battery park to e 161st is 35 minutes. However, it takes a few minutes to walk from the 161st stop to the stadium, so you would need to budget in extra time (so 3:22 would be too late even though it gets in before 4:00 pm). The best train would be the 3:12 because it would get in at 3:47, giving you plenty of time to walk from the station to the stadium.
Answer:
D) The government gets it's authority from the people
Explanation: The preamble begins <em>"We the People"</em>, because it is stating the importance of the people in the United States government. The whole point of the American Revolution is the goal of creating a government that works by the "consent of the governed" and that gives power to the people.
Of course, this would not be stating that the United States is on its own, they make plenty of allies during the Revolution, and the Founding Fathers would never be a replacement for the king, since they are fighting against the idea of a Monarchy.
Spinal cord injuries occur when there's damage to the spinal cord. The result is loss of function, usually in mobility or feeling. Severe injuries that occur in the neck usually result in Quadriplegia, which is paralysis from about the shoulders down
