mayb=)I guess both methods could be used
this is sound wave my dear....wat u saying is for light and electromagnetic waves
i rote the rate would be same cz it only depnds on intensity..bt ds is rong..actually the rate will be reduced=(What was the answer for the one where it asked for the effect on emission of electrons if u maintained the intensity of light but increased its frequency? Also which of the given metals would electrons be emitted from?
im not sure of dat..atleast fr formula will get 1 markYeah, but if I'm remembering correctly, the question said that a radio wave was being modulated, ravio waves belonging to the EM spectrum and travelling at c (3x10^8 ms-1)

chk 2011 mj v-1 ques 7 c part two and chck ms an er..ul get itI also put that it remains the same. How sure are u that it's wrong?
Add...... all the mass defects?! :SIn the nuclear fusion reaction, were we supposed to add all the mass defects and use E= mass defect * c^2 ??
Wasn't just throwing... add the volumes, add the moles... get the answer. I also said the two cylinders acted like one. xDFor the charged sphere, I calculated the voltage of of the particle as well, and I got 300something. And said that it wouldn't reach the sphere.
For the two cylinder one- I also got 356 K, but I don't think it would be that easy... I left that part and did it last.. I mean it was for 3 marks, there's more to it then simply throwing the numbers in the formula.. Idk. :/
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
