- A viscous fluid flows in two different pipes. Pipe 1 has a radius r1, and Pipe 2 has a radius r2. If both pipes have the same length and r1 > r2, choose the correct statement about the pressure difference of the fluid in Pipe 1 and Pipe 2 The pressure difference of the fluid is the same in Pipe 1 and Pipe 2. The fluid in Pipe 1 has larger pressure difference. It cannot be determined in which pipe the fluid has larger pressure difference. The fluid in Pipe 2 has larger pressure difference.What is true about the volume of displaced fluid for an object that is completely submerged? (1 Point) The volume of displaced fluid is equal to the object's volume. The volume of displaced fluid is less than the object's volume. The volume of displaced fluid is greater than the object's volume. The volume of displaced fluid is not related to the object's volume.ption 4Given: A woman of m = 51 kg stands on the ice. The contact area between her skate and the ice is A = 0.0061 m2 Express the force that the person exerts on the ice, F, in terms of m and g. You do not need to include the force of the column of air above her. Calculate the numerical value of F in N. Express the pressure on the ice from the person P in terms of F and A. Calculate the numerical value of P in Pa
- The container shown is filled with a mystery liquid with density 15,000 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 × 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.The figure below shows a container filled with three fluids, A, B, and C. The tops of the 3 tubes are open to the atmosphere. Fluid B in tube 2 rises highest. The top of fluid A in tube 1 is 4.0 cm below the top of fluid B and the top of fluid C in tube 3 is 2.5 cm below the top of fluid B. The column of fluid B in tube 2 is 10cm high and the column of fluid C in tube 3 is 4.5 cm high. Fluid A has a density of 1000 kg/m³.

Explain.
- A geologist finds that a moon rock whose mass is 8.25 kg has an apparent mass of 6.15 kg when submerged in water. What is the density of the moon rock? Given that the density of water is 1,000 kg/m³. Include a diagram of the situation.True or False? The higher the velocity of the fluid the lower the pressure.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.
