E average standard rectangular building brick has a mass of 3.10 kg and dimensions of 225 mm x 112 mm x 75 7. The gravitational field constant g = 9.8 N/kg. Calculate the pressure the brick creates when standing on its surface of greatest area

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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?

Argon, neon, and xenon are examples of
