Oil with r=876kg/m3andμ=0.24kg/m. sis flowing through a 1.5-cm-diameter pipe that dischargesinto the atmosphere at 88kPa. The absolute pressure 15m before the exit is measured to be 135kPa,. Determine the flow rate of oil through the pipe of the pipe is(a)horizontal, (b)inclined 8°upward from the horizontal, and (c)inclined 8°downward from the horizontal.

Two polarizers are oriented at 70∘∘ to one another. unpolarized light falls on them. what fraction of the light intensity is transmitted?

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?
