The definition of speed is (distance covered) / (time to cover the distance) .
So a unit of speed has to be (a unit of length) / (a unit of time) .
Here are several perfectly fine units of speed:
-- miles per hour
-- feet per second
-- meters per second
-- kilometers per hour
-- inches per second
-- centimeters per minute
-- yards per Century
-- furlongs per fortnight
-- nanometers per microsecond
-- Smoots per week
-- parsecs per millenium
Answer:
Possible options:
A. nA, nC, nB
B. nA, nB, nC
C. nC, nB, nA
D. nC, nA, nB
E. nB, nA, nC
Answer is D
Explanation:
When the light is refracted into liquid B it is bent away from the normal, so that nA > nB. When the light is refracted into liquid C it is bent toward the normal, so that nC > nA. Therefore, we conclude that nC > nA > nB
Answer:
troposphere and stratosphere
Answer:
Line A is fastest and Line D is slowest
Explanation:
Line A is the fastest moving object because the bar is steepest. Line A travelled the furthest in the least time, so Line A is moving fastest. Line D is the slowest object because the bar is least steep. Line D travelled the least distance in the most time, so Line D moves the slowest.
<em>Hopefully the answer and explanation helps!</em>
