Using a compound microscope with a resolving power of 0.3 m, a 10 ocular lens, and a 100 oil immersion lens, would you be able to discern two objects separated by 3 m? 0.3 m? 300 nm? 3000 Å?

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
