Atall tube is evacuated, and its stopcock closed. the open end of the tube is immersed into a container of water (density 103 kg/m3) that is open to the atmosphere (pressure 105 n/m2). when the stopcock is opened, how far up the tube will the water rise? a.1 m b.5 m c.10 m d.20 m

Explanation:

It is given that,

Density of water,

Atmospheric pressure,

The pressure exerted at a height h is given by :

g is acceleration due to gravity

h = 10.2 meters

or

h = 10 meters

So, the water will rise to a height of 10 meters. Hence, this is the required solution.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
