1. Find an equation for the terminal velocity of a sphere falling through a viscous fluid (like water or blood). How does the terminal velocity scale with the size of the falling object? Assume that the density of that object is much larger than that of the fluid through which it falls (neglect buoyancy).
a. V ~ L^-3b. V ~ L^0c. V ~ L^1d. V ~ L^2e. V ~ L^3
2. A person is bowling with a 8 kg bowling ball. Their arm is 1 m long. If they pull the ball back 0.7 m (hint: call this A) and use no muscle effort to accelerate their bowl (gravity provides the driving force), what is the stress in the bones of their arm during the swing, just as the arm passes the straight up-and-down position. Treat the arm as a simple pendulum with one long bone, and assume that the cross-sectional area of this bone is 2 cm2. Neglect the mass of the arm itself.
a. 4.8 x 106 dyn/cm2b. 2.7 x 106 dyn/cm2c. 3.9 x 106 dyn/cm2d. 6.0 x 105 dyn/cm2e. 5.8 x 106 dyn/cm2
A capacitor is constructed of two concentric conducting cylindrical shells. The radius of the outer shell is 2.59x10^-3 m, and that the inner cylindrical shell is 2.45 x10^-3 m. When the cylinders carry equal and opposite charges of magnitude 1.54x10..

A teeter-totter is made of a 4.200 meter long plank with a mass of 38.0 kilogram, with a fulcrum (pivot point) located 2.400 meters from the right end. find what mass must be located at the left end
The bonding of silicon in solids and molecules is qualitatively the same as that of carbon. Silicon atomic states become molecular states and in a solid, these effectively form the valence and conduction bands.
two identical capacitors are connected in parallel to an ac generator that has a frequency of 650 hz and produces a
