Chapter 22, Problem 9P
What is the angular size of Phobos observed from Earth when Mars and Earth are at closest approach? Compare that with the resolution limit of about 1 arc second for ground-based telescopes. (Hint: Use the small-angle formula, Eq. 3-1.) (Notes: Necessary data to derive the distance between the objects in that situation are given in the Celestial Profiles for Earth in Chapter 19 and Mars in this chapter. For the size of Phobos, use the maximum dimension given in the text.)

Your blood pressure (usually given in units of "mm of Hg") is a result of the heart muscle pushing on your blood. The left side of the heart creates a pressure of 115 mm Hg by exerting a force directly on the blood over an effective area of 14.5 cm2. What force does it exert to accomplish this? (Give your answer as the number of Newtons and note that you will need to do some unit conversions.)
What is the absolute (total) pressure experienced by a diver at a depth of 17 meters below the surface of a lake? Assume that atmospheric pressure at the surface of the lake is 101,000 Pascals, g= 9.8 m/s2, and the density of the water in the lake is 997 kg/m3. Give your answer as the number of Pascals.
A particular solid cube has an edge of length 0.59 meters and is made of a material whose density is 3500 kg/m3. What is the mass of the cube? Give your answer as the number of kilograms.
