    Mathematics: Post your doubts here!

    I get it now. Thank you soo muchh!! I couldn't afford a school or academy so studying all by myself and this helped alot. Thanks again.

    Mathematics: Post your doubts here!

    I didnt know thats how you get the phase shift. I first sketched the graph of y=csc(2x) and then shifted it pi units to the right (y=csc(2x-pi)) is this wrong? I've been doing this for a long time and always got the right answers.

    I'm so sorry but yes thats what im asking. The graph of y=csc2x should be the same as y=csc(2x-pi) but it only shift pi/2 units to the right, why?

    the graph of y= csc(2x) should repeat it self 😣! I'm sorry for bothering you. You can just ignore me now.

    how would you sketch the graph of y=csc(2x-pi) for -2pi<x<2pi? wouldn't the graph be the same as y=csc(2x) since the period is pi so graph will shift pi units to the right and it should stay the same, right?

    can anyone help with part (a)? I was getting 0,180, 360, but the answer at the back is 180 only. It could be a typo, but just wanna make sure.

    Physics: Post your doubts here!

    but the potential needs to be changing; we need to have two values of potential to get potential difference which is exactly what was given. What i have figured is that the charge is what's changing cuz in one of the earlier parts of question it says charge required to raise sphere to a...

    in the last part why cant we find the work done using change in potential=workdone/charge. and since workdone is the change in energy it should be valid right? it doesnt give the right answer.

    can anyone explain Q11 (b) (i)? I read an explanation somehwere and it said that the two forces have to be subtracted because they are opposite in direction. Why subtract when both forces are in same direction? Shouldn't we add? Both springs will exert a force to the left to bring it to the...

    Can anyone explain why (c) (iii) is 180? Shouldn't the phase difference be slightly less than 180?

    A small charge q is placed in the electric field of a large charge Q. Both charges experience a force F. What is the electric field strength of the charge Q at the position of the charge q? A) F/(Qq) B) F/Q C) FqQ D) F/q Answer is D, why isn't it B? :O HELP

    Chemistry: Post your doubts here!

    I'm not that good in chemistry, but from my understanding it cant be a,b, or d because these three properties are also present in NaCl and MgO and the question says that CsCl has a different structure than these two, so the only distinct property that CsCl has is the radii ratio.

    isotopes can have more neutrons. Wouldn't that mean they'd have bigger radii?
