Unpolarized light passes through two polaroid sheets. the transmission axis of the analyzer makes an angle of 30.5° with the axis of the polarizer.

(a) what fraction of the original unpolarized light is transmitted through the analyzer? (enter your answer to at least three decimal places.)

(b) what fraction of the original light is absorbed by the analyzer?

Does baby oil have a high or low velocity?

The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. in part iii, you will be investigating the questionable baseball. use the drop-down menus to complete the sentences and identify the independent and dependent variables. in part iii, the independent variable, the one that is intentionally manipulated, is . in part iii, the dependent variable, the one that you measure the response in, is

Amachine, modeled as a simple spring-mass system, oscillates in simple harmonic motion. its acceleration is measured to have an amplitude of 5,000 mm/s with a fre- quency of 10 hz. compute the maximum displacement the machine undergoes during this oscillation.
