A large tank has a tube coming out of it like a straw, as shown in the picture below. The tube of water is entirely full and closed at the end on the right, while the tank is open to the air.
Rank the pressures at points N, U, C, L, E, A, and R (using <, >, and =). Explain your reasoning.
How does the pressure at point R compare with the atmospheric pressure immediately outside of the straw? Explain your reasoning.
Describe what would happen if you held the right end of the straw (near point R) in place and poked a hole in the end of it. (This is how a siphon works.) Explain your reasoning. (A video of you doing this experiment yourself could be submitted as evidence of your reasoning.)
Imagine two blocks as shown in Figure 10A-1. The two blocks, with the same size bases, are resting on the horizontal surface of a table. Each block pushes down on the underlying surface with a force (weight) that is ______ the downward force exerted by the other block.a.different fromb.equal toc.twice
By definition, pressure is the amount of force acting on an area of surface. Pressure is calculated by dividing the force exerted on a surface by the area over which the force is applied. The blocks weigh the same and their bases have the same area, so the two blocks exert ______ pressure on the underlying surface.a.half theb.the samec.twice the
