I think the correct answer from the choices listed above is option D. The model of the universe that suggests that the sun is the center of the universe was first brought by Copernicus. His model is known as the "Sun centered model".
Answer: 16 m
Explanation:
Since this situation is about constanta acceleration, we can use the following equations:
(1)
(2)
Where:
is the bike rider's final velocity
is the bike rider's initial velocity
is the time at which we need to find the bike rider's distance
is the constant acceleration
is the bike rider's traveled distance
From (1) we can find :
(3)
(4)
(5)
Now, we can substitute (5) in (2) and find the traveled distance :
(6)
(7)
Finally:
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
