When in a confined fluid the pressure is increased in one part than the pressure will equally distribute in the whole system.
According to Pascal's law when pressure is increased in the confined system then the pressure will equally transfer in the whole system.
This law's application is used in machines like hydraulic jacks.

The side where the light from the sun hits the moon is facing away from earth.
Answer:
An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.

In order to lift the fat (306 lb) physics professor 89 meters up to
the rim, he'll need more potential energy, equal to
(mass) x (gravity) x (height) = (139 x 9.8 x 89) = 121,236 joules .
If the faithful horse delivers 1 constant horsepower = 746 watts,
AND if the cute-as-a-button student has instantly figured out a
way to keep the rope sliding around the edge without any friction,
then the soonest Prof. Tubby can arrive at the rim is
(121,236 joules) / (746 joules/sec) = 162.5 seconds .
Nowhere in this tense drama has the student needed her linguistics
skill yet, but I'll bet it comes in handy as she attempts gamely to
comprehend all of the various pleadings, prayers, and expletives
uttered by her heavy hero from the time he falls over the rim until
he's again lifted to it.
