Se tienen 5 cm3 de aire encerrado en una jeringa, siendo p = 760
mmHg. Para reducir el volumen que ocupa el gas se ejerce presión,
manteniendo constante la temperatura:

a- Calcula qué presión habrá que ejercer sobre el émbolo de la
jeringa para que el volumen sea una décima parte menor que el inicial.
b- ¿En cuánto debe aumentar la presión para que el volumen se
reduzca a la mitad?

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?
