Which is the most accurate statement about the heating curve and energy?

a) moving from a to c the temperature and the kinetic energy increases.

b) moving from c to a the temperature decreases but the kinetic energy increases.

c) although the temperature increases, there is no information about energy change.

d) as time elapses, the substances turns into plasma and has the highest kinetic energy.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
