Answer:
The pressure is
Explanation:
From the question we are told that
The gauge pressure at the mouth is
The radius of the column is
The speed of the liquid outside the body is
The area of the column is
The area inside the mouth
Generally according to continuity equation
=>
=>
=>
So
=>
=>
substituting values
Now the height of inside the mouth is
Now the height of the column is
Generally according to Bernoulli's equation
Now which is the density of water
is the gauge pressure of the atmosphere which is zero
So
1-D Eustress is a positive response
2-B resistance
3-A Imagine you are doing your gymnastics
