## A tuning fork of frequency 542 Hz is placed near the top of the pipe shown in th Science Assignment Help

A tuning fork of frequency 542 Hz is placed near the top of the pipe shown in the Figure. The water level is lowered so that the length *L* slowly increases from an initial value of 20.0 cm. Determine the next two values of *L* that correspond to resonant modes. (Assume that the speed of sound in air is 343 m/s.)

## comparative analysis Business Finance Assignment Help

( Memorandum format )

You need to determine AT&T’s position in the market by conducting a basic comparative analysis of AT&T versus a competing company within the industry(Verizon). You must submit a memo to the company CEO and make an oral presentation explaining the company’s financial strength and its strength compared to the selected competitor at a company strategy meeting.

You need to compare five key indices of financial strength:

•Stock price – 1 year, 6 month, Intra-day (Use on or about 01/23/2015 as the present date)

•Sales/Revenue (over the last three full-years)

•P/E Ratio

•Net Income (over the last three full-years)

•EPS

-Introduction ( Information without numbers, purpose of statement, and bottom-line)

-Prescriptive heading-line for each paragraph.

-Deductive structure paragraph.

-Good world choice.

-Paragraph should be concise and to the point.

-Use more transition in/between paragraphs.

-Each paragraph has to start with topic sentences and end with bottom-line.

-Charts and graphs must be cited(Line-bar graph for net income,revenue, and stock -price)

-APA style.

-Answer all the points on the part 1

-Please READ the assignments carefully

-Follow the rubric is IMPORTANT

-Follow the same memo example I attached

At least Five sources.
