A hydraulic piston has two surfaces which can move when a force is applied to them. On the left side, the piston surface is circular with a cross-sectional radius of 10 cm and on the right side it is square with a side of length 30 cm. A. If I push on the left side with 100 N of force, what total force will be exerted by the fluid in the piston on the right side? B. If I displace the piston on the left side by 18 cm, how far will the right surface move?

A piece of copper has a mass of 2.6 kg. a.What is the volume of this piece of copper?  b.The copper is then totally submerged in water. What is the buoyant force acting on it?  c. What is the piece of copper’s apparent weight in the water?

Hi please help: A cylindrical container with a cross-sectional area of 69.2 cm^2 holds a fluid of density 856kg/m^3. At the bottom of the container the pressure is 128kPa. Assume Pat= 101kPa A. What is the depth of the fluid? B. Find the pressure at the bottom of the container after an additional 2.25x10^-3m^3 of this fluid is added to the container. Assume that no fluid spills out of the container

Fluids & Pressure 16. A 50.0-kg woman balances on one heel of a pair of high heeled shoes. If the heel is circular and has a radius of 0.500 cm, what pressure does she exert on the floor? 17. A glass tube contains mercury. What would be the height of the column of mercury which would create pressure equal to 1.00 atm? 18. A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a 240-g rock that displaces 89.0 cm³ of water?

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe has a diameter of 17.0 cm. The lower end of the pipe has a diameter of 8.60 cm. The speed of the water at the upper end is 2.00 m/s.What is the flow rate of the water in the pipe?

A raft has dimensions 7.0 m x 7.0 m with a thickness of 1.0 m and made of material with average density 650 kg/m3.    a. When floating in water, what percentage of the volume is under water?   b. What is the pressure underneath the raft?   c. How heavy of a load is necessary to cause the raft to be 80% submerged in water?   d. If the raft is made with a different material of lower density and 80% of it is still submerged, how if at all would your answers to (a), (b) and (c) change?   e. , explain how, if at all, the answer to (b) is related to the buoyant force. f. Imagine that the load increases enough to fully submerge and then sinks the raft to the bottom of the lake.  How, if at all, does the buoyant force vary during this process?

The container shown is filled with a mystery liquid with density 15.1 ×103 kg/m³. It is open to atmosphere on the left and closed on the right. What is the pressure at point A, in kPa (kiloPascal)? 1.0 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s². Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. y (cm) 100- 75 50 25- 0 B
