first variant or second variant dude? or p22 or p21?
PLS reply asa[p ?????
HElp needed for aslevel practicals !!! how to do the part that has describes a relation means h is directly proportional to x^2 ?
1st exp result H= 7.5 cm x=4.0
2nd exp result H=31.2 x=8.50

IN paper three that is practiacl there is a common ques " JUSTIFY THE NUMBER OF SIGNIFICANT FIGURES ? " how to solve that ?
i think you have to give a reason like this that you have been giving your answers in the previous measured quantities in 3 s.f so that's why using the same number of s.f throughout.IN paper three that is practiacl there is a common ques " JUSTIFY THE NUMBER OF SIGNIFICANT FIGURES ? " how to solve that ?
1) rms of an ac is equal to the constant dc that produces same power or heating effect in a identical resistor. for a sinusoidal graph, rms voltage and rms current is (peakvoltage/under root of 2) and (peak current/under root 2) respectivelyAoA wr wb
1 what does RMS value of ac voltage mean? plz explain and hw do u find it?
2 whats the difference b/w peak to peak voltage and peak voltage
3 anyone knows an easy mnemonic for the electromagnetic spectrum including the wavelengths?
2) peak voltage means the max voltage or the max amplitude in a graph. peak to peak means twice of amplitude. it means from the lowest peak to the highestAoA wr wb

sorry i dont have any idea about thatJazakallah
and the spectrum? any tip on memorizing it?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
