# Finding the Speed, Frequency and Period of Tsunami Waves

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

Tsunamis are fast-moving waves generated by underwater earthquakes. In the deep ocean their amplitude is barely noticeable, but upon reaching the shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutian islands in Alaska, had a wave length of 650 km and traveled a distance of 3700 km in 5.6 h.

(a) What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about 250 m/s.

(b) Find the wave's frequency.

(c) Find the wave's period.

## Quantitative Research on Job Markets

See the attached file.

As a researcher, the mastery of creating well-written and measurable hypotheses, problem statements, and research questions is critical. A grant or project proposal is often won or lost based on the strength of a researcher's skill in this area. This Discussion Board will give you an opportunity to improve your technique while peer reviewing your classmates' proposals. Using the topic from your Unit 1 DB post, select 1 data-collection idea, and write the following:

A quantitative hypothesis and a null hypothesis

Explain why you feel this is an important topic to investigate and why a quantitative method would be appropriate.
A qualitative research question with 3 guiding questions

Explain why you feel this is an important topic to investigate and why a qualitative method would be appropriate.
A summary of ethical responsibilities that align with the selected topic and method

Include three peer review sources.
