Acoffee filter in the shape of an inverted cone (8 inches in diameter and 4 inches tall) is dripping coffee. there is a cylindrical coffee pot (10 inches in diameter and 6 inches tall) below the cone. how fast is the height of the coffee in the pot increasing when the level of coffee in the filter is 2 inches and decreasing at a rate of .2 inches per second?

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

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 mantle is made up of which structural zones?
