Which describes why the sun is a renewable resource? the sun creates biomass. the sun is continuously releasing energy. the sun does not cause pollution.

In a system, when potential energy decreases, then entropy also decreases. true false

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.

Which accounts for an increase in the temperature of a gas that is kept a constant volume
