Quick Physics Check Please

Hey Basil ,

Were learning about static/dynamic fluids and I just want to check if my answers are correct to the following questions because I can't change them once I submit them, if anyone can check my answers that would be greatly appreciated =D:

1) We place a small pressure sensor at a certain depth in water. With which orientation does the sensor register the greatest pressure, or is the reading the same in all directions?

sensor facing upward

sensor facing downward (I chose this.)

same in all directions

2) Which is another name for the total pressure at a point in a tank of water?

gauge pressure

absolute pressure (I chose this.)

3) If we lower a pressure sensor down into a tank of water, what happens to the gauge pressure?

increases with increasing depth (I chose this.)

decreases with increasing depth

remains constant with increasing depth

4) If the atmospheric air pressure increases, what happens to the height of the mercury column in a mercury barometer?

increases (I chose this.)

decreases

remains unchanged

5) Which describes the function of a hydraulic lever?

magnifies an applied force (I chose this.)

magnifies an applied pressure

magnifies an applied work

6) If an object is submerged in water, how does its apparent weight compared with its true weight?

it is more than the true weight

it is less than the true weight (I chose this.)

7) How is the volume flow rate through a pipe related to the cross-sectional area of the pipe and the speed of the flow?

It is equal to the ratio of the speed to the area.

It is equal to the product of the area and speed. (I chose this.)

It is equal to the ratio of the area to the speed.

8) How is the mass flow rate through a pipe related to the volume flow rate and the density of the fluid?

It is equal to the product of the volume flow rate and density. (I chose this.)

It is equal to the ratio of the volume flow rate to the density.

It is equal to the ratio of the density to the volume flow rate.

9) If the width of a horizontal pipe increases, what happens to the kinetic energy density of a fluid flowing smoothly through it?

increases (I chose this.)

decreases

remains the same

Sorry if its so much, thanks again for any help, I really appreciate it! =)
