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.

- 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?arrow_forwardNeeds Complete typed solution with 100 % accuracy.arrow_forwardDRAW ALSO A FREE BODY DIAGRAM OR FIGURE.arrow_forward

- Hi I got 4.33x 10^-7 m^3/s is this correct? If not please show all steps so I can see where I went wrong. Thank you!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_forwardNeeds Complete typed solution with 100 % accuracy.arrow_forward
