By conducting exhaustive, high-intensity online research for about 15 seconds, I found a source that says the speed of sound in copper is 4600 m/s. (You could easily have completed the same research project in about 1/3 of the time it took you to type and post the question here.)
Time it takes = (distance) / (speed)
Time = (25,000 meters) / (4600 m/s)
Time = (25 / 4.6) km-sec/km
<em>Time = 5.43 seconds </em>
The answer is B. Hemorrhage and Arthritis
Answer:
Explanation:
given,
mean of hospital waiting (μ) = 38.12 min
standard deviation (σ) = 8.63 min
worst waiting time = 20%
the are will be same as the = 100 - 20%
= 80%
we have to determine the z- value according to 80% or 0.80
using z-table
z-value = 0.85
now, using formula
The wall will push back with an equal and opposite force, as defined by Newton's Third Law, so the wall will exert -200 N of force
I would say C because Instigator means <span>a person who brings about or initiates something. I hoped that helped </span>
