A 7.59-m-tall container is filled to the brim, partway with mercury and the rest of the way with water. The container is open to

the atmosphere. What must be the depth of the mercury so that the absolute pressure on the bottom of the container is twice the atmospheric pressure?

Answer:

1.0335 m

Explanation:

Atmospheric pressure, Po = 1.01 x 10^5 Pa

Let the depth of mercury is h

the depth of water is 7.59 - h

density of mercury = 13.6 x 10^3 kg/m^3

density of water = 1000 kg/m^3

Pressure due to mercury + pressure due to water = 2 x Po

height of mercury x density of mercury x g + height of water x density x g

                                        = 2Po

h x 13.6 x 1000 x g + (7.59 - h) x 1000 x g = 2 x 1.01 x 10^5

h x 13.6 x 9.8 + (7.59 - h) x 9.8 = 2 x 1.01 x 100

133.28 h + 74.382 - 9.8 h = 202

123.48 h = 127.618

h = 1.0335 m

Thus, the height of mercury column is 1.0335 m.

Answer:

0.22 m

Explanation:

P_{o} = Atmospheric pressure = 101325 Pa

P = Pressure at the bottom = tex]2 P_{o}[/tex] = 2 (101325) = 202650 Pa

h = height of the container = 7.59 m

x = depth of the mercury

Pressure at the bottom = Atmospheric pressure + Pressure due to mercury + Pressure due to water

P = P_{o} + \rho _{w} g (h - x) + \rho _{hg} g x\\2 P_{o} = P_{o} + \rho _{w} g (h - x) + \rho _{hg} g x\\P_{o} = \rho _{w} g (h - x) + \rho _{hg} g x\\101325 = (1000) (9.8) (7.59 - x) + (13600) (9.8) x\\x = 0.22 m

can you help me create a sketch of two different objects with one that has a greater density than the other?
sergey [27]

I don't know how good you are at sketching ... I'm terrible. 
But you can put the point across in a dramatic way if you
can sketch a bowling ball and a basketball ... you'll need
to clearly identify them with the markings you sketch on
each ball. 

They're the same shape and nearly the same size, but
there's a huge difference in their densities.

3) Magnets are used to separate steel cans from aluminum cans in recycling plants. How can
Elden [556K]

Answer:

Since steel contains iron (a magnetic metal), the magnets will attract the steel cans since aluminum is not magnetic. This is used to separate the steel cans from the aluminum cans so they can be recycled separately.

Think about lifestyle choices that you make on a daily basis. Choose at least four lifestyle choices which you could change to i
eimsori [14]
A.The four lifestyle choices which I could change are:
1. The amount of physical exercise I engage in on a daily basis.
2, The number of hours I sleep.
3. The quantity of junk foods I consume daily and 
4. Cultivation of the habit of spending time alone daily.
B. My days are always very busy, so I do not engage at all in physical exercise. Adding at least a thirty minute of physical exercise to my daily tasks will improve my health considerable. Due to the nature of my day, I usually eat on the move, thus I eat junk foods everyday. Eating healthy and balanced diet will go a long way in improving my health. I sleep for three hours only everyday, from 2 am to 5 am.This is because I have to leave my house very early in the morning and I don't usually get to sleep until 2 am in the morning. Spending more hours sleeping will improve my overall health. I want to start spending at least 30 minutes alone on a daily basis in order to meditate and to reflect over the events of the day. This will be a great boost to my mental health.
