It takes a ball about 0.45 seconds to drop 1 meter so for a ball to drop about 51 meters would take 22.95 seconds. Multiply 51 by 0.45. Hope this helps

worty [1.4K]

Answer:

E. After “robots”

Explanation:

Answer E

Correct. The underlined text is a modifying phrase that describes the word “robots.” By placing the phrase directly after the word it modifies, the writer can reduce ambiguity in the sentence. This choice makes it clear that the modifying phrase refers to robots, not people.

Helicopter blades withstand tremendous stresses. In addition to supporting the weight of a helicopter, they are spun at rapid ra
Radda [10]
NOTE: Check your formula sheet if you have one these are often there.

Ac = \frac{V^{2} }{r} = rω^2

We know r = 4.00m

but what is ω?

ω = \frac{2π}{T} = 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.
