A beam of light of fixed intensity is directed at a linear polarizing filter whose transmission axis is at an angle of 45∘ above the positive ‑axis. For which incident polarization does the filter reduce light intensity the most?

(A) The incident light is unpolarized.

(B) The incident light is polarized parallel to the ‑axis.

(c) The incident light is polarized at an angle of 45∘ below the positive ‑axis.

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?

Acertain half-reaction has a standard reduction potential e_red^0 = -0.94 v. an engineer proposes using this half-reaction at the cathode of a galvanic cell that e must provide at least 1.00 v of electrical power. the cell will operate under standard conditions. a. is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? b. is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have?

Humid air is a better electrical conductor than dry air. explain why you are most likely to receive a shock after walking across a carpet when the air is dry than when the air is humid.
