You performed an experiment in which you measured the amount of water leaking through different types of roofs. for one roof, you measured a volume of 13.2 ounces. what is this measurement in si units? 1 lb oz; 1 kg =2.2 lbs.

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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 speed of light can be used to measure the
