A camera draws 0.25 amps and with 72 ohms. what voltage supply does this camera need?

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o
