    I Does the sequence converge or diverge? (2^n)/(2n)

    I am bound to use nth term for the second part. Its mentioned in the question. I'll give it a try.

    I Does the sequence converge or diverge? (2^n)/(2n)

    Can you kindly explain how to solve both of them ?

    I Does the sequence converge or diverge? (2^n)/(2n)

    So there are two parts of the question: a) does the sequence converge or diverge b) use nth term on the Series Now sybomlab calculator is saying to apply ratio test! a) b) So should I apply ratio test or is there any easy method? And what's the difference between these two questions and...

    Question about a Flip Flop circuit

    Hello! I am confused in a question I found on youtube. I have uploaded the screen shots. He told that with respect to S and R we have to write the change from Q to Q+( next state). But I am not getting it. How he wrote Q+ states?Is he considering that when S=1 , we have to set the circuit i.e on...

    Can all the multiplexers work for any number of variables given?

    Can all the multiplexers work for any number of variables given? For example can I make a 16:1 multiplexer for 2 variables inputs, A and B?

    Drawing 4-2 Priority Encoder Circuits

    Hello guys! I am getting confused in drawing the circuit for a priority encoder. Because I saw some youtube videos and also on google , they all are drawing 4 to 2 priority encoder differently.These both are 4 to 2 priority encoders.

    How do the charges in 3 cancel each other out in net electrostatic force?

    Got it bro! Thanks!

    How do the charges in 3 cancel each other out in net electrostatic force?

    I am still not getting it. Can you explain how in 3 the center has the highest net force?

    How do the charges in 3 cancel each other out in net electrostatic force?

    if we let the centre charge to be positive then obviously the negative ones will attract it while the positive ones will repel it. Now the question is about the net electrostatic force. See these explanations.

    How do the charges in 3 cancel each other out in net electrostatic force?

    Here is the question no1 in image. A charge is in between . We will let it possitive or negative. The answer is 3,1,2 4...But how? Won't the charges in 3 cancel each other out because they are possitive at right and negative at left. One is attracting so the other is repelling.

    Which of the options describes the phase constant for SHM?

    So how option a and b are correct? I am not getting the question? What is he asking? Sorry I am very weak in this topic.

    Which of the options describes the phase constant for SHM?

    The only thing I know is that phase constant tells how much a signal is shifted along the x-axis. The answer of the question is both option a and b. I am not getting it!

    What is Applied Physics and Why is it Important?

    Hey guys! My name is Salman Ali. I am from Pakistan. Right now I am doing bachelors in computer science from Fast University. The reason I joined Physics Forums was that I am studying Applied Physics as one of the major subject so I will be happy to exchange knowledge regarding this subject...
