Death Valley holds the record for the highest recorded temperaturein the United States. On July 10, 1913, at a place called FurnaceCreek Ranch, the temperature rose to 134°F. The lowest U. S.temperature every recorded occurred at Prospect Creek Camp inAlaska on January 23, 1971, when the temperature plummeted to-79.8°F.

(a) Convert these temperatures to the Celsiusscale.
T = 134°F 1°C
T = -79.8°F 2°C

(b) Convert the Celsius temperatures to Kelvin.
T = 134°F 3 K
T = -79.8°F 4 K

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?
