Imagine that a small hole is opened in the container wall near the bottom of each layer.
1. Predict what will happen to the water near each hole. Explain.
2. Check your prediction by observing the demonstration. Record your observations. (Asketch may be helpful.)
What do your observations suggest about: (1) the existence of horizontal forces on thethree layers of water in pan A? (2) the relative magnitudes of the horizontal forces onthe three layers?
If necessary, revise your free-body diagrams in part A so that they are consistent withyour answers.

On an episode of a popular TV series, the hosts attempted to determine whether this is possible. According to the hosts' experiment, such an event cannot happen. Did they need to perform the experiment? As a science adviser to the show, the hosts ask you to perform a crude calculation to test the myth. A typical jet plane travels at 542 mph at a cruising altitude of 25500 ft. The windows on a jet plane measure 14.0 in x 14.0 in. Calculate the force F exerted on such a window as the plane flies at 25500 ft above the sea level. Assume the density and pressure of air at 25500 ft are 0.562 kg/m³ and 382 mbar, respectively, but that the interior of the plane remains pressurized to atmospheric pressure, 1 atm. lb F = Calculate the fractional difference between this force and the weight wman of a typical adult male (185 lb). F Wman How…arrow_forwardFor this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?arrow_forwardExplain salient features of the liquid Drop model.

- 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 thearrow_forwardSolve the problems below. 1.
