https://prnt.sc/h3cwy7 Can someone explain this? My thoughts were it would be D, as from the right hand rule we get that the current will move from X to Y. Hence, X will be the positive terminal and Y will be the negative terminal, as positives are attracted to negatives. However, am I wrong...

http://imgur.com/vm1I8cD Hey, so the answer is C but I really don't get how. Can someone show me the method to do this?

So I was doing the 2013 HSC and came across this question. The answer is B. I'm wondering why there would be no current produced by the generator? Would it not still exert a force on the electrons, thus producing a current? I recognise that eventually a charge would build up and the current...

Hey, I would like with this question: http://m.imgur.com/9SUPIEr Thank you.

Hey guys, I need help with these two questions: http://m.imgur.com/a/39Qms Any help would be greatly appreciated, thanks.

Hey, can someone explain the locus questions such as arg(z-a)-arg(z-b)=θ, because I don't really understand them. Same with arg(z-a)+arg(z-b)=θ

Hey, I need help with two questions: http://imgur.com/YmMw5kd http://imgur.com/hVWn0OS I only need help with a) ii) and c) iii) B), but the whole question is needed to solve it so I posted the whole thing. Thanks.

Here are the questions: http://m.imgur.com/scXruJa I'm not really sure how to start on the questions in 17, and I can't do 18.

Hey, I'm trying to do a question but I keep getting a different answer for the first part: The answers say that F(n+1)-2=((2^n)+1)((2^n)+1) but when I was doing the question I got F(n+1)-2=((2^n+1)+1)((2^n+1)-1). Can someone show me how to get the answer, thanks.

Hi, I have some questions that I have no idea how to do, here they are: http://m.imgur.com/Ro7qBgm Thanks

This is a two part question: a) Point M divides the interval AB internally in the ratio 1:x in such a way that AM is the geometric mean of BM and BA, find x and draw a diagram. b) Point M divides the interval externally in the ratio 1:x in such a way that AB is the geometric mean of AM and BM...

25. The line passing through M(a,b) intersects the x-axis at A and the y-axis at B. Find the equation of the line if: (a) M bisects AB, (b) M divides AB in the ratio 2 : 1, (c) M divides AB in the ratio k:l 26. The tangent to a circle is perpendicular to the radius at the point of contact. Use...

Hi this is the question: Find the number of ways in which the letters of the word EPSILON can be arranged in a row so that the three vowels are all next to each other. I let the three vowels be V, and the four constants be C VCCCC You can arrange the whole thing 5! ways, then the vowels 3...

Here is the question: Find the equations of the four circles which are tangent to the x-axis, the y-axis, and the line x + y = 2. I don't really know where to start. Thanks!

The question is cosxtanx+tanx=cosx+1, I don't know what to do. Thanks. Also 6sinxcosx+3sinx=2cosx+1, it's the same type of question.
