1. For a soap bubble, the inside pressure must be greater than that outside, and the surface tension acts like a skin to support this pressure difference Ap. The pressure difference is then a function of surface tension σ and bubble radius R, i.e., Ap = f(o, R). Using Buckingham Pi theorem, find the II group(s) associated with this problem and express them in the form II₁ = (II2, ..., II-r). (Ans: ApR = constant) σ

A tremendous force is generated when waterfreezes into ice and expands in volume by 9.0%. Suppose a 1.000-m3cube of liquid water freezes into ice that is 1.000 m on a side by1.090 m tall. How many 68-kg students would the ice be able tolift? Determine this by calculating the amount of force on the top1.000-m2face that would be required to squeeze 1.090 m3of iceback to 1.000 m3, assuming all of the volume change occurs alongthe vertical direction

2 A US Navy nuclear submarine (mass m = 10,000,000 kg) is cruising under the Arctic ice sheet at a depth of 200 m. (a) If the submarine is maintaining constant depth while cruising, what is the size of the buoyant force on it? (b) Assuming that the density of seawater is 1023 kg/m3, what is the volume of the submarine? (c) What is the water pressure at the cruising depth of the submarine (remember that the pressure increase due to the depth has to be added to the pressure at the surface, which is the atmospheric pressure PATM = 101,000 Pa)?

Find the net force on this window (i.e., force from outside minus force from the inside) assuming that the air pressure inside the submarine is equal to PATM.
As measured by NASA’s Viking landers, the atmosphereof Mars, where g ≈ 3.71 m/s 2 , is almost entirely carbondioxide, and the surface pressure averages 700 Pa. The temperatureis cold and drops off exponentially: T ≈ T o e - Cz ,where C = 1.3E-5 m - 1 and T o = 250 K. For example,at 20,000 m altitude, T ≈ 193 K.

In the following section, at least 2 to up to 5 answers may be correct. 1) For a fluid, the assumption (simplifying notion) of incompressibility has important consequences: Pascal’s principle: a change of pressure in an enclosed fluid at rest is transmitted undiminished to all points in the fluid. pressure changes are transmitted immediately from one place to another. the speed of sound then is infinite (just within this approximation). pressure becomes unpredictable. none of the above. 2) Archimedes’ principle can be summarized as: an immersed object is buoyed up by a force equal to the weight of the fluid it displaces. a bathtub is fun, and may lead to important physical discoveries regarding the volume of an object and how much water it displaces, and the weight of that amount of water. boats swim because of the work done by sailors. submarines are always doomed. fish swim because they are less heavy than water 3) A…
