a).
b).
c.) It must be at the bottom
Explanation:
Given:
Volume flow
Well depp
a.
The power output of the pum
b.
The pressure of difference the pum
Δ
Δ
c.
It must be at the bottom since the pressure difference is greater than atmospheric pressure, so it wouldn't be able to lift the water all the way
The correct answer is
B It increases.
In fact, the kinetic energy of a moving object is given by
where m is the mass of the object and v is its speed. We see that the kinetic energy is proportional to the mass and proportional to the square of the speed: in this problem, the speed of the object remains the same, while its mass increases, therefore the kinetic energy will increase as well.
