Extreme wind will cause windows to shatter and burst outwards. Explain which principles of physics govern this phenomenon and how it occurs

5. A large container, 118 cm deep is filled with water. If a small hole is punched in its side 89.0 cm from the top, at what initial speed will the water flow from the hole? m/s ceil6 ceil cci16 ceil6 c

3. In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.155 atmospheres below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure differential.

1. The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in figure. Determine the gage pressure of air in the tank if h1 = 0.4 m. h2 = 0.6 m, and h3 = 0.8 m. Take the densities of water, oil, and mercury to be 1000 kg/m3, 850 kg/m3, and 13,600 kg/m3, respectively. Oil Water AN Mercury

You want to test whether your bar of gold is pure or not. It has a mass of 1000 g when you measured in air and 960g when totally submerged in water. Is your bar of gold pure or not? The density of pure gold is 19.3 g/cm3. If not, what is the percentage of impurities?

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.

Three glass containers containing water of the same temperature have different shapes and thickness. The distance between the top surface of the water and the bottom of each glass container is the same. Which of the following statements correctly characterizes the pressure at the bottom of the glass containers? (explain why) 2 3 a. Pressure at the bottom of all glass containers is the same. b. Pressure at the bottom of (2) and (3) are the highest because they have the same volume. c. Pressure at the bottom of (2) is the highest because it is wide. d. Pressure at the bottom of (1) is the highest because it is narrow. e. Pressure at the bottom of (3) is the highest because it is vertically aligned.

2. Water flows through a fire hose of diameter 6.35 cm at a rate of 0.012 m³/s. The fire hose ends in a nozzle of inner diameter 2.20 cm. What is the speed with which the water exits the nozzle?

9. A liquid is flowing through a horizontal pipe whose radius is 2.22 x10-2 m. The pipe bends straight upward through a height of 9.8 m and joins another horizontal pipe whose radius is 3.82 x10-2 m. What is the speed of the liquid in the lower horizontal pipe if the pressure in both horizontal pipes is the same? x L0228) m/s

A sea exhibit at an aquarium is 24 meters long and 11 meters deep with a glass wall. It is open to the air at the very top. i. What is the total pressure at the top of the tank (including atmospheric pressure)? ii. What is the total pressure at the bottom of the tank (including atmospheric pressure)? iii. The other side of the glass wall is at atmospheric pressure. What is the total net force on the wall? (hint: the pressure changes linearly as a function of depth, so you can use the average pressure to find the force)
