Answer:
The water will rise to a height, H = 10.20 m
Given:
Atmospheric Pressure, P =
density of water,
Solution:
The water in the tube will rise to the point where the weight is balanced by the force as a result of the atmospheric pressure.
Therefore,
Pressure, P =
where
g = acceleration due to gravity = 9.8 m/s
H = height of water in the tube
Now,
Putting the values in the above formula:
H = 10.20 m
We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
You're going to use the constant acceleration motion equation for velocity and displacement:
(V)final²=(V)initial²+2a(Δx)
Given:
a=0.500m/s²
Δx=4.75m
(V)intial=0m
(V)final= UNKNOWN
(V)final= 2.179m/s
