Consider a spherical shell of mass density ?m = (A/r) exp[ -(r/R)2], where A = 4 x 104 kg m-2. The inner and outer shell radii are 3R and 4R respectively where R = 6 x 106. Find the inward gravitational acceleration on a particle of mass mp at a position of 4R. The spherical di erent is dV = r2 dr sin? d? d?.

A) 9.00 m/s2

B) 2.36 m/s2

C) 9.3 m/s2

D) 2.3 m/s2

E) 3.00 m/s2

You have three sheets of 2 × 4 m cardboard. You cut squares of side x from each of the twelve corners. You fold up the resulting flaps on the three sheets to make 3 open-topped boxes, and you use the twelve squares to form two cubes. Maximize the total volume

Consider a reduced deck where all cards 2, 3, 4, and 5 (16 cards) are removed. In a game of five card draw find the number of ways to draw one pair, two pair, three of a kind, straight, flush, full house, four of a kind, straight flush, and royal flush.

CA1.11 (LO 2, 4) (Models for Setting GAAP) Presented below are three models for setting GAAP.

1. The purely political approach, where national legislative action decrees GAAP.
2. The private, professional approach, where GAAP is set and enforced by private professional actions only.
3. The public/private mixed approach, where GAAP is basically set by private-sector bodies that behave as though they were public agencies and whose standards to a great extent are enforced through governmental agencies.

Instructions

1. Which of these three models best describes standard-setting in the United States? Provide justification for your answer.
2. Why do companies, financial analysts, labor unions, industry trade associations, and others take such an active interest in standard-setting?
3. Cite an example of a group other than the FASB that attempts to establish accounting standards. Speculate as to why another group might wish to set its own standards.

Exhibit 2-4

Michael's Compute-All, a national computer retailer, has kept a record of the number of laptop computers they have sold for a period of 80 days. Their sales records are shown below:

For questions 2 to 4 d, consider two 2.00 L flasks, one of which contains 0.250 mole of O₂

gas at 50.0 deg C and the other of which contains 0.500 mole of H₂ gas at 50.0 deg C.

2.      Which sample contains more molecules? Show your calculation. (6 pt)

3.      Which sample has the greater mass? Show your calculation. (6 pt)

4.      a.      In which flask is the ratio of molecular volume (volume occupied by the

                  molecules touching one another in a condensed state) to gaseous sample

                  volume (volume occupied by the entire gaseous sample) greater? (2 pt)

         b.      What is the approximate value of these ratios? Explain. Calculation

                  not needed (4 pt)

         c.      In which sample do the molecules have higher average kinetic energy? Explain.

                  Calculation not needed (4 pt)

         d.      In which flask do the molecules have higher average speed? Explain.

                  Calculation not needed (4 pt)

3. Consider the following data for two variables, x and y.

x   2 3 4 5 7 7 7 8 9

y 4 5 4 6 4 6 9 5 11

a. Does there appear to be a linear relationship between x and y? Explain.(f-test, to do f-test for the overall significance)

b. Develop the estimated regression equation relating x and y.

c. Plot the standardized residuals versus yˆ for the estimated regression equation developed in part (b). Do the model assumptions appear to be satisfied? Explain.

d. Perform a logarithmic transformation on the dependent variable y. Develop an estimated regression equation using the transformed dependent variable. Do the model assumptions appear to be satisfied by using the transformed dependent variable? Does a reciprocal transformation work better in this case? Explain.
