Question

Which of the following statement is NOT true.

• A. A freely falling body is acted upon by gravitational force
• B. pressure on top of mount everest is much more than 1 atm
• C. S.I. unit of pressure is pascal
• D. the blood vessels in our body maintains the internal pressure equal to the atmospheric pressure

Answer 1

Answer: (B), (D)

The correct options are
B pressure on top of mount everest is much more than 1 atm
D the blood vessels in our body maintains the internal pressure equal to the atmospheric pressure

A free falling object is an object that is falling under the sole influence of gravity.
Atmospheric pressure decreases with height above the surface of a planet because there is less total mass in the atmosphere above a reference point as the height of the reference point increases. The standard atmospheric pressure at sea level is 1 atmosphere.
Pressure is generally measured in units of Pascals and S.I. unit of pressure is pascal.
The normal atmospheric pressure is 760 mm of Hg. But the normal human blood pressure is around 120/80 mm only.
Answer (B) & (D)
(B) pressure on top of mount everest is much more than 1 atm
(D) the blood vessels in our body maintains the internal pressure equal to the atmospheric pressure
