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.

Q)
Summation from 1 to infinity
(1+(-1)^i) / (8i+2^i)
This series apparently converges and I can't figure out why.

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

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. :)

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.

Yes, and that is my question.

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?
