Do you think that the rock in the picture took more or less time to cool than the rocks formed from magma beneath Earth's surface? Why?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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.
