Problem 9E If Earth were smaller than it is, but the Alexandria-to-Syene distance were the same, would the shadow of the vertical pillar in Alexandria be longer or shorter at noon during the summer solstice?

By evaluating their dot product, find the values of the scalar s for which the two vectors b = x + s'Sr and c = x sS7 are orthogonal. (Remember that two vectors are orthogonal if and only if their dot product is zero.) Explain your answers with a sketch.

Consider the cube balanced on a cylinder as described in Example 4.7 (page 130). Assuming that b < r, use the Lagrangian approach to find the angular frequency of small oscillations about the top. The simplest procedure is to make the small-angle approximations to before you differentiate to get Lagr

A 0.620-kg wood block is firmly attached to a very light horizontal spring (k = 180 N/m) as shown in Fig. 8-35. This block-spring system, when compressed 5.0 cm and released, stretches out 2.3 cm beyond the equilibrium position before stopping and turning back. What is the coefficient of kinetic fric

A converging lens (f1 5 24.0 cm) is located 56.0 cm to the left of a diverging lens (f2 5 228.0 cm). An object is placed to the left of the converging lens, and the fi nal image produced by the two-lens combination lies 20.7 cm to the left of the diverging lens. How far is the object from the conver

A very small object with mass 8.20 * 10-9 kg and positive charge 6.50 * 10-9 C is projected directly toward a very large insulating sheet of positive charge that has uniform surface charge density 5.90 * 10-8 C>m2 . The object is initially 0.400 m from the sheet. What initial speed must the object ha

The New York Times reported (Feb. 17, 1996) that subway ridership declined after a fare increase: There were nearly four million fewer riders in December 1995, the first full month after the price of a token increased 25 cents to $1.50, than in the previous December, a 4.3 percent decline. a.
