Problem 8 (12 pts). Let L(a, b) be the length of the graph of the function   on the interval . Let M (a, b) be the length of the ellipse with the major axis a and minor axis b. Find M (a, b) / L(a, b).

1. Let r(t) = (t, t, cos t).
(a) (20 points) Plot r(t), t greater than or equal to 0.
(b) (20 points) Find the direction of motion when speed is maximized.
(c) (20 points) Find the normal component of acceleration when speed is
maximized.
(d) (20 points) Find all points on the curve where maximum curvature is

Five balls, numbered 1 to 5, are placed in order on a table. A sequence of steps is performed on the balls. In step 1, the rightmost ball is picked up and put in the middle of the four remaining balls. (The remaining balls are shifted to make room for the inserted ball.) Then in step 2, the leftmost ball is picked up and put in the middle of the four remaining balls. These steps repeat, with the rightmost and leftmost balls alternately picked up and put in the middle of the four remaining balls. Immediately after step N, the balls are in the reverse of their original order. Which of the following is a possible value of N?

A consumer values a car at $30,000 and a producer values the same car at $20,000. If the transaction is completed at $24,000, the transaction will not take place if:

b. The tax is smaller than the buyer surplus

c. The tax is equal to the seller surplus

d. The tax is larger than the total surplus

In a transaction for a good valued at $100,000 by a buyer and $95,000 by a seller, what
amount of tax would result in an unconsummated transaction?
a. Any tax amount would result in an unconsummated transaction.
b. A tax of $1,500
c. A tax of $5,500

Figure out how to profitably consummate the unconsummated wealth-creating transaction
created by rent control

Identify an unconsummated wealth creating transaction (or a wealth destroying one) created by some tax , subsidy, price control or other government policy, and than figure out how to profitably consummate it ( or deter it) estimate how much profit you earn by consummating (or deleting) it.

When a metal was exposed to light at a frequency of 3.82× 1015 s–1, electrons were emitted with a kinetic energy of 5.60× 10–19 J. What is the maximum number of electrons that could be ejected from this metal by a burst of light (at some other frequency) with a total energy of 1.40× 10–7 J?

When light of frequency equal to 2.30 × 10¹⁵ s^−1 shines on the surface of silver metal, the kinetic energy of ejected electrons is found to be 3.5 × 10^−19 J. What is the work function of silver? Enter your answer in scientific notation.

1. The work function of potassium is 3.68 × 10 -19 J. (a) What is the minimum frequency of light
