Amercury manometer (rho = 13,600 kg/m3) is connected to an air duct to measure the pressure inside. the difference in the manometer levels is 30 mm, and the atmospheric pressure is 100 kpa. (a) judging from fig. p1–65, determine if the pres- sure in the duct is above or below the atmospheric pressure. (b) determine the absolute pressure in the duct

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
