Homework Statement
Use the picture as a guide. P is the pressure in the pipe, and vi is the speed of a non-viscous incompressible fluid at locations i = 1,2,3,4,5.(For each statement select G-Greater than, L-Less than, or E-Equal to).
A) P1 is ... P4
B) v1 is ... 2v3
C) P4 is ... P5...
The water only exerts a downward force on the tank, so the answer must be false since its asking for does it have an upward component.
Force/area = pressure
Force/area = density*g*height
Force = density*g*height*area
BUT the area does not stay the same with height. it is larger on the bottom...
Well, what I think the question is asking is that does the water exert an upward force on the container (i think), so I presume it means something like this

Which it certainly is not making contact with, so it should be false.

The three tanks shown above are filled with water to an equal depth. All the tanks have an equal height. Tank A has the greatest surface area at the bottom, tank B the least and tank C the middle.
(Select T-True, F-False, G-Greater than, L-Less than...
Thanks, I appreciate the help. The question was about time from quickest to slowest. A later question was about the period, which is opposite of the above order.
Thanks for the link.
So to find the forces, it would be something like this?:
A) Total spring constant = k, F= -kx
B) Total of springs: k + k = 2k, F= -2kx
C) 1/k + 1/k = 2/k, (2/k)^-1 = k/2, F = -(k/2)x
D) k + k = 2k, F = -2kx
so order would be D=B>A>C?
Same would apply to part B of the...
Homework Statement
Consider the four block-and-spring systems shown. Each block moves on a horizontal, frictionless table. The blocks all have the same mass and all of the springs are identical and ideal with spring constant k. At the instant shown, each block is released from rest a distance...
