An electron in level c of a mercury atom is struck by a photon, causing it to move up to level g. What was the energy of the absorbed photon, in electron-volts? * What was the frequency of the absorbed photon from the previous problem, to two decimal places? *

** urgent** the voltage across the primary winding is 350,000 v, and the voltage across the secondary winding is 17,500 v. if the secondary winding has 600 coils, how many coils are in the primary winding? a- 30 coilsb- 583 coilsc- 12,000 coilsd- 332,500 coils

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
