This cross section of the lower troposphere at 12Z on some morning shows two air columns and the 850-mb constant-pressure surface. Note the station model between the two air columns. The data listed on the station model came from a radiosonde released from the airport at Point M. A reasonable pressure at Point P is while a reasonable corresponding height at Point P is.

Two polarizers are oriented at 70∘∘ to one another. unpolarized light falls on them. what fraction of the light intensity is transmitted?

What is the major limitation to the light microscope?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
