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

good for her? ? where is the question?

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
