The average intensity of light emerging from a polarizing sheet is 0.689 w/m2, and that of the horizontally polarized light incident on the sheet is 0.930 w/m2. determine the angle that the transmission axis of the polarizing sheet makes with the horizontal.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
