 * 1) 6 like when the water is coming out of the end of the hose, if you put your thumb over part of the hole the force shoots the water farther and the smaller the hole the more force and the more pressure the water exerts.
 * 2) 7- The small piston of a hydraulic lift has an area of .2m^2. A car weighing 1.2 X 10^4N sits on a rack mounted on the large piston. The large piston has an area of .9m^2. How large a force must be applied to the small piston to support the car?

In a hydro-energy plant, Water travels through a pipe from under a dam to a turbine at the power plant. If a small pipe is used, there will be more pressure than in a large pipe and, as such, will cause the water to flow faster. 7. ||

 * 1) 6 Boats obviously deal with this always. When making a boat, it is important to decide how big it is, what material it is made from, and how much weight it is meant to carry without sinking. These details are especially important for a cruise ship, of which being the next Titanic is the last thing the people in charge need.
 * 2) 7The highest natural concentration of salts in water are found in the evaporating remnants of old oceans, such as the Dead Sea in Israel. Suppose a swimmer with a volume of .75m^3 is able to float just beneath the surface of water with a density of 1.02 X 10^3 kg/m^3. How much extra mass can the swimmer carry and be able to float just beneath the surface of the Dead Sea, which has density of 1.22 X 10^3 kg/m^3?

 * 1) 6 when you pour oil into your car there are different viscosities and the thicker viscosity takes longer to pour because its thicker. its just like pouring water and syrup out of different cups the water will be gone first because it is not as thick and has a thinner viscosity
 * 2) 7 A 2.0 cm diameter faucet tap fills a 2.5 X 10^-2m^3 container in 30.0 s. What is the speed at which the water leaves the faucet? ||
 * || P-9.5 || [|Explain how depth and fluid density affect pressure.]
 * 1) 6 you can take a empty can and drop it into the ocean and it will go to a certain depth and get crushed thats because
 * 2) 7 IN 1969, a whale dove and remained underwater for nearly 2h. Evidence indicates the the whale reached a depth of 3.00km, where the whale sustained a pressure of 3.03 X 10^7Pa. Estimate the density of sea water.
