Physics Question on Electromagnetic waves
Air is blown through a hole on a closed pipe containing liquid. Then, the pressure will
A
increase on sides
B
increase downwards
C
increase in all directions
D
never increase
Answer
increase in all directions
Explanation
Solution
From PascaI's principie which was stated in 1652 by Biaise PascaI, according to which a change in pressure applied to an enclosed incompressible fluid is transmitted undiminshed to every portion of the fluid and uo the walls of its container. This pressure change is independent of height. Hence, on biowing air through a closed pipe containing Iiquid, pressure will increase in all directions.
