The pressure is measured at the bottom of a cylindrical container with cross-sectional area A that is filled to a height H by a liquid with density rhoL . A cube of volume Vc and density rhoc is placed in the liquid and floats partially submerged, causing a change Δh in the height of the liquid. As a result, the pressure at the bottom of the container increases.
In a coherent, paragraph-length response, describe the relevant forces acting on the cube and the liquid, and explain how they result in the increase in pressure at the bottom of the container.
Write an expression for the pressure at the bottom of the container in terms of H , Δh , and physical constants, as appropriate.
Determine Δh in terms of Vc and other given quantities and physical constants, as appropriate.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

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?
