9. d. If Excel does not fill the column, fill the range G6:G40 with the formula in cell G5. The Sales table is currently sorted by the values in the Sale ID column, but Benicio wants to sort the table by date, then amount to make it easier to track the data. Apply a custom sort to the Sales table to sort it in ascending order first by the values in the Date column, and then by the values in the Amount column. 10. Benicio wants to make sure that the Sales table does not contain any duplicate records, which would make any sales analysis incorrect. Identify and remove duplicate records in the Sales table as follows: a. In the range A5:A40, create a conditional formatting Highlight Cells Rule that formats Duplicate Values in Light Red Fill with Dark Red Text. b. Delete the second duplicate record from the table. (Hint: Do not delete the row from the worksheet.) 11. Benicio might want to filter the Product Details data in the range 14:M16, so he asks you to format it as a table. Format the range 14:M16 as a table using Light Gray, Table Style Medium 14 to match the Sales table. 12. To make it easier to refer to the data, assign the table name Details to the table in the range 14:M16 to make it easy to refer to the data. (Hint: Rename the table, not the range.) 13. Benicio wants to examine the January, 2022 sales by country and channel. Create a PivotTable based on the Sales table as follows: a. On a new worksheet, insert a PivotTable based on the data in the Sales table, and use January Pivot as the name of the worksheet. b. Display the Channel Type values as column headings. c. Display the Location values as row headings. d. Sum the Amount values

Two identical 9 N bar magnets rest on a wooden table with a coefficients of static and kinetic friction both equal to 0.40. The force exerted between the magnetic poles is $20250/x^3$ N where x is in mm and is the distance between the magnets. The magnets are slowly pushed towards one another until they suddenly jump together. What is the relative speed with which they collide? The center of magnetism for each magnet is 6.25 mm from the end. FULL CREDIT AWARDED ONLY FOR ACCRUATE FBD AND KINEMATICS DIAGRAMS ANS. $v_{rel} = 0.346 m/s$
