I'm familiar with the concept, but I do not see the link between that and my scenario. Could you please elaborate, or perhaps link me to some texts that help me understand it a little better?

Hello. I need some help understanding time dilation. So the idea is that moving clocks tick slowly. Say there was an observer A who, by his frame of reference, is stationary, and he sees an object B moving past it at high velocity. From what I understand, to A it would appear as if B's clocks...

1. In the network given (Fig.1), the initial voltage on C1 is V1 and on C2 is V2 such that v1(0)=V1 and v2(0)=V2. At t=0 the switch K is closed. (a) Find i(t) fo all time. (b) Find v1(t) for t>0. (c) Find v2(t) for t>0. (d) From your results on (b) and (c), show that v1(∞)=v2(∞)...

Point. I just checked my textbook and it appears I'd mistakenly thought that just because Summation 1-infinity (ai+bi) equals summation 1-infinity (ai) + Summation 1-infinity (bi), I thought the same would be true for multiplication. Thanks for clearing it up.

1. A cobalt-60 source having a half-life of 5.27 years is calibrated and found to have an activity of 3.50 × 105 Bq. The uncertainty in the calibration is ±2%. Calculate the length of time, in days, after the calibration has been made, for the stated activity of 3.50 × 105 Bq to have a maximum...

Oops, this should have been in the "Advanced Physics" section. Can a mod please move this?

Hello. I believe there's a flaw in my understanding of the operational amplifier. I'm getting a bizarre result that I'd really appreciate if anyone can help me with. :) 1. http://tinyurl.com/6e9ovvp The part I'm having problem with is Q9 (b) (iv). 2. V=IR The Attempt at a...

Thanks a lot for clarifying it! And no you didn't confuse me at all. Again, I appreciate your help. I have a major exam in 3 days.

No, I know that the phase angle is between 0 and 360, but that's not the problem. According to my teacher, in Q.1, the "phase difference" is either 0 or 180, depending upon the direction of motion of the points. No other value can take place, since two points can either be moving in the same or...

Understood. Thanks a lot :) . One more question, please. Is there a difference between, "phase angle" and "phase difference"? There's a question I came across (let's call it Q.1) in which we were to find the 'phase difference' between two points on a stationary wave. All we needed to do there...

I forgot an important detail in the question statement. Amplitude of the waves are 3x10^-4 and 2x10^-4 cm. I know how to solve the question by finding the amplitude of the resultant wave and using a ratio: Amp. (Amp') of resultant wave I' = (3-2)x10^-4 cm. I'/I= [(Amp'.)^2 x (Freq^2)]...

You nearly knocked me into a coma with the part in bold. I haven't read this formula yet. I can't tell what the "e" stands for. Here's the original question: http://tinyurl.com/34gkevc Q.5, part (c). Yes, and that is my question. If we are to find the resultant intensity of two waves...

Statement: 1. The intensity of wave A at point P is I. Intensity of wave B at point P is (4/9)I. The phase difference between these two waves 180 degrees. Wavelength of A and B is 3x10^-4 and 2x10^-4 cm respectively. Frequency of both waves is "f". What is the resultant intensity at P in terms...

Are the particles on either side of a node 180 out of phase? Let's say there's a stationary wave, and X and Y are two points on either side of a node, moving in opposite directions. Are X and Y 180 degrees out of phase with each other? Homework Equations None The Attempt at a...
