When a garden hose with an output diameter of 20 mm is directed straight upward, the stream of water rises to a height of 0.16 m . you then use your thumb to partially cover the output opening so that its diameter is reduced to 10 mm. how high does the water rise now?

The density of a liquid could be found by using

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?
