Question
Reliving the “good old days” several physics faculty decide to spend a warm balmy summer’s day squirting each other with garden hoses right in front of the physics building. They place their thumb over the end of the hose, and the water squirts out very quickly, because their thumb increases
A.
the energy of the water.
B.
the potential energy in the hose.
C.
the pressure of the water in the hose
D.
the speed of the water in the hose.
A.
the energy of the water.
B.
the potential energy in the hose.
C.
the pressure of the water in the hose
D.
the speed of the water in the hose.
Explanation / Answer
The Thumb Increases the Pressure of the water in the hose. Answer is (C), since you are reducing the size of the opening, volume decreases and hence pressure increases.
