Thanks a lot!

Bqv= mv^2 / r
now r= mv / Bq (shown)

Is there a specific trend in graph or just have to modulate the frequency!
How to draw a amplitude modulation graph!
Thanks alot

Plz someone explain these quickly thnx in advance........

http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_s04_qp_4.pdf for 5ci how is the ratio 2 i get the formula but im not getting the answer and for 5dii why is the rms 3A?

http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_w02_qp_4.pdf 2b which is actually a really easy question but im confused it would be really helpful if someone provides a drawn n labelled diagram

http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_w04_qp_4.pdf can anyone solve 6c with steps i cant get thru

this is Am not Fm...Am mein amp change for Fm frequency change hota hai when info signal is changed.... wen info signal is +ve so high frequency nd vice versa..

The lines represent photons of specific energy.Photons are emitted as a result of energy change of electron as it jumps to higher energy levels..Their r specific energy changes so discrete energy levels.
