You observe a binary system and see Doppler shifts in the Hβ lines from the two stars of 0.02 nm and 0.05 nm respectively. Patient observations show that the period is 22 years. If the system is inclined by 60◦ , what are the masses of the two stars?

The ABC Company runs two shifts, from 8:00 am to midnight. Backups and system maintenance are performed between midnight and 8:00 am. For each of the following scenarios, determine whether the company’s current backup procedures enable it to meet its recovery objectives, and explain why: Scenario 1: Recovery point objective = 24 hours Daily backups at 3:00 a.m., process takes 2 hours Copy of backup tapes picked up daily at 8:00 a.m. for storage off-site Scenario 2: Company makes daily...

Sorting with Binary Search Tree This assignment asks you to sort the lines of an input file (or from standard input) and print the sorted lines to an output file (or standard output). Your program, called bstsort (binary search tree sort), will take the following command line arguments: % bstsort [-c] [-o output_file_name] [input_file_name] If -c is present, the program needs to compare the strings case sensitive; otherwise, it's case insensitive. If the output_file_name is given with the -o option,...

You are using a poorly constructed 4-bit natural binary-coded absolute encoder and observe that

You are using a poorly constructed 4-bit natural binary-coded absolute encoder and observe that, as the encoder rotates through the single step from code 3 to code 4, the encoder outputs several different and erroneous values. If misalignment between the photosensors and the code disk is the problem, what possible codes could result during the code 3-to-4 transition?

6. A) You observe the following quotes for the USD/AUD in the spot market from two banks: Bank of Sydney Bank of New York Bid Ask Bid Ask 0.71711 0.71715 0.71708 0.71715 Do these quotes imply the possibility of earning a profit by using locational arbitrage? If so, calculate the potential profit if you are able to use AUD 25,000. If not, explain why arbitrage is not possible? B) You observe the following quotes for the GBP /AUD in the...

At starbase Faraway Point, you observe two spacecraft approaching from the same direction. The Picard approaches starbase Faraway Point with a speed of 0.806 c, and the La Forge approaches the starbase with a speed of 0.918 c. Suppose the Picard now launches a probe toward the starbase. What velocity must the probe have relative to the Picard if it is to be at rest relative to the La Forge? What velocity must the probe have relative to the Picard...
