ok thanks a lot

Hmm how can you be sure that the angle between the 12 o clock filter and 1 o clock filter is 30 degrees though?

Homework Statement Unpolarized light of intensity Io passed through a Polaroid sheet with its polarizing axis at the 12 o'clock position and then through a second with its polarizing axis at the 1 o'clock position. What is the intensity of the emerging light? Homework Equations [/B] I= I0...

Well we used 2 magnets but my teacher said we could perform the same experiment with just 2 charges and why were we not offered to use an electric fied than magnetic field in this case

Homework Statement Using magnetic field over electric field Homework Equations no equation needed The Attempt at a Solution THis may not make sense but did an experiment dealing with the inverse square law and we measured the magnetic field in this case. Want to know is there some type of...

So in this circuit potential energy is dropped because the charges are moving from capacitor to capacitor. And ultimstely the charges want to go to a lower energy state. Is this some how related to like the potential drop from I guess in this case high energy to low energy?

Didn't want to create another thread but for my first question with the picture of the capacitor circuit I calculated the initial energy with q^2/2C and got 0.313micro joules then calculated the final with C=60 then used the same equation for the final energy q^2/2C=0.208 but I want to know how...

hmm ok so what exactly could you call the equation P=V^2/Z x cos(theta)? Apparent power dissipated through resistance? but what about the impedance?

Ok thanks a lot

Ok thanks a lot. Dont want to make another thread so i thought id ask this question here to see if I am right An uncharged 30.0-µF capacitor is connected in series with a 25.0-Ω resistor, a DC battery, and an open switch. The battery has an internal resistance of 10.0 Ω and the open-circuit...

Ok so where would the current flow from? since i guess no voltage or emf is present, the current would initially flow from the 40µF?

Yea this was the initial question- In the circuit shown in the figure, all the capacitors are air-filled. With the switch S open, the 40.0-µF capacitor has an initial charge of 5.00 µC while the other three capacitors are uncharged. The switch is then closed and left closed for a long time...

Thats how the circuit was given to me in the question lol

fixed

Homework Statement 2. Homework Equations [/B] No equations needed The Attempt at a Solution I know that capacitors are used to store charge but what exactly is the 40 micro-farad capacitor doing? No emf/voltage is shown so is the 40 micro-farad capacitor acting like the emf/voltage? or is it...
