On december 26, 2004, a great earthquake occurred off the coast of sumatra and triggered immense waves (tsunami) that killed some 2 people. satellites observing these waves from space measured 800 from one wave crest to the next and a period between waves of 1.0 hour. part awhat was the speed of these waves in m/s? express your answer using two significant figures.=part bwhat was the speed of these waves in km/h ? express your answer using two significant figures.=

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?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
