1of 2) calculate the speed, c, (in meters per second) of a tsunami with a wavelength of 180,000 meters (180 kilometers or112 miles) and period of 15 minutes traveling over the pacific (which has an average depth of 4000 meters (4 kilometers or 2.5 miles). round up your answer so that there is no decimal.
note that the answer is not 200 m/s as it is incorrect
2 of 2) using the speed of the tsunami that you calculated above, answer the following question:
how long would it take (in hours) for a tsunami to arrive at the coast of southern california if it was generated by an earthquake off the coast of japan? (the distance between tokyo and la is approximately 9,000,000 meters 9,000 km)
you will first need to calculate how many seconds, then convert seconds to minutes, and finally convert minutes to hours. you answer should be in hours.
round your answer to the first decimal place (for example 10.634 would be rounded to 10.6)
note that the answer is not 12.5 hours

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
