ASK YOUR TEACHER PRACTICE ANOTHER Three liquids that do not mix are poured into a cylindrical container with a diameter of 10.0 cm The densities and volumes of the liquids are as follows Liquid 1: p1 = 2030 x 103 kg/m3 and i/jl = 1090 x 10-3 m3 Liquid 2: p2 = 1.00 x 103 kg/m3 and v2 = 1.80 x 10'3 in3 Liquid 3: g = 0.600 x 103 kg/m3 and v3 = 1.00 x 10-3 m3 Determine the pressure on the bottom of the container.

The gure below shows a spherical water tank that holds 6.00 x 105 kg of water when full. Note that the tank is vented to the atmosphere at the top and that the pipe delivering water to customer Smith is a height h = 7.50 m above the level of the pipe delivering water to customer Jones. Determine the gauge pressure of the water at the faucet of each house when the tank if full. Smith house Jones house (a) Jones house SP3 (b) Smlth house Pa 5. [-11 Points] WAUNIPHVSAV1 12.P.016. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A reservoir dam has a vertical surface in contact with the water that is 132 m wide and 17.5 m high. Air pressure is one atmosphere. If the reservoir is completely lled, determine the magnitude of the net force acting on the darn. (Hint: Since the pressure varies linearly with depth, you will need to use your knowledge of calculus in order to determine the force on the dam due to water. Use 100 x 103 kg/m3 for the density of water.) I:N 6. [-I1 Points] WAUNIPHYSAV1 12.P.024. ASK YOURTEACHER PRACTICE ANOTHER Calculate the maximum force in newtons exerted by the blood on an aneurysm, or ballooning, in a major artery, given the maximum blood pressure for this person is 135 mm Hg and the effective area of the aneurysm is 245 cm2. Note that this force is great enough to cause further enlargement and subsequently greater force on the ever-thinner vessel wall. (Use 13.5 x 103 kg/m3 as the density of mercury.) N 7.

If your car has a mass of 1275 kg and is supported equally by its four tires, determine the following. (a) Contact area between each tire and the road 2 "-2 (b) Will the contact area increase, decrease, or stay the same when the gauge pressure is decreased? 0 increase 0 decrease 0 stay the same (c) Gauge pressure required to give each tire a Contact area of 123 cm2 :W 8.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A rectangular parallelepiped with a square base d = 0.250 m on a side and a height h = 0.120 m has a mass m = 6.00 kg. While this object is floating in water, oil with a mass density po = 710 kg/m is carefully poured on top of the water until the situation looks like that shown in the figure. Determine the height of the parallelepiped in the water. m oil ho hw water (129 Tutorial 9. [-/1 Points] DETAILS WAUNIPHYSAV1 12.P.032. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An antique coin is a mixture of silver and copper. The coin has a mass of 1.090 x 10-2 kg and in water weighs 0.1011 N. Determine the mass of silver in the coin. Use 1.05 x 104 kg/m as the density of silver, 8.89 x 105 kg/m as the density of copper, and 1000 kg/m3 as the density of water. kg 10. [-/1 Points] DETAILS WAUNIPHYSAV1 12.P.037. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A 5.85-m radius air balloon loaded with passengers and ballast is floating at a fixed altitude. Determine how much weight (ballast) must be dropped overboard to make the balloon rise 106 m in 16.0 s. Assume a constant value of 1.2 kg/m for the density of air. Ballast is weight of negligible volume that can be dropped overboard to make the balloon rise. N
