Explanation:
A.
Using the wave equation:
v = d/t
Where,
v = velocity
d = distance
= 23.5 km
= 23500 m
t = time
= 2m 30s = 150 s
v = 23500/150
= 156.7 m/s
B.
From the calculated value above, it can be seen that the velocity of the heat blast is >>> than the velocity of sound above sea level.
Answer:
The detector temperature doesn't affect retention time
Explanation:
Retention time is one of the chromatographic parameters. Is defined as the time of a compound spends from injection to detection.
A solute in GC is added to the injector where is volatilized. When volatilized, it pass through a column until the detector.
The detector temperature doesn't affect retention time. To change retention time you must change injector temperature or column temperature. An increase in column or injector temperature results in a decrease in retention time.
Answer:
They are standing 3 feet away from each other
Explanation:
If Nathan Is standing 2 feet away from the mirror. Then Hiva is standing 7 feet away from the mirror is she is standing 5 feet further than him. They are standing 3 feet away from each other.
The answer is <span>B. the amount of hot soup contained in a bowl. Buoyancy is defined as the upward force exerted by a fluid on an object immersed in that fluid. Buoyancy and density are two factors that affect the downward and upward forces exerted on object that affect its ability to "float" or "sink". Only B does not have anything to do with such forces.</span>
