Which of the following best explains the polarity of water (h2o)? a. electrons are more attracted to the oxygen atom, so there is a partial negative charge on the oxygen atom. b. since the oxygen atom has more electrons than the hydrogen atoms, it is negatively charged. c. since there are two positive hydrogen atoms and only one negative oxygen atom, the water molecule is positively charged. d. protons are more attracted to the hydrogen atoms, so the hydrogen atoms become positively charged.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
