A beam of unpolarized light with a power of 1 mW passes through a linear polarizer with a vertical transmission axis, and then through another linear polarizer with its transmission axis at 50 degrees to the vertical. What is the light beam power after the second polarizer, assuming the polarizers are ideal (i. e. they do not absorb any power in the transmitted polarization)

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output
