The nucleus of a tellurium-130 atom contains 52 protons. Assume that the nucleus is a sphere with radius 5.51 fm and with the charge of the protons uniformly spread through the sphere. At the nucleus surface, what are the magnitude and direction of the electric field produced by the protons

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?
