Chapter 12.1, Problem 1cT
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.

In the event of an emergency, a nuclear reactor is shut
down by dropping the control rod R, having a weight of
20 lb, into the reactor core C, as shown in (Figure 1).
A
If the rod is immersed in "heavy" water, which offers a drag resistance to downward motion of FD = (0.25v) lb, where v
is the velocity of the rod in ft/s, determine the distance s it must descend into the reactor core when it attains a speed of
14 ft/s. The rod is released from rest when s = 0. Neglect the effects of buoyancy.
Express your answer in feet to three significant figures.

1. The permeability constant for a vacuum is ų0, has a value of 4(pi)×10-7 Tm/A. Assuming the equation B=ų0nI applies to the Slinky, obtain a value of (pi) from your graphs, and compare with the 'theoretical' value.
2. Was your Slinky positioned along an east-west, north-south, or on some other axis? Will this have any effect on your readings?

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).
