5*235*(1240-300)+(5*105*10^3)+(5*235*100)=95*129*(x-1340)
solve it..........
heat gain by silver=heat loss by gold
solve it..........
heat gain by silver=heat loss by gold

1. In frequency modulation, amplitude doesnt change!Anyone who can explain me this.. ??

Q11
a(ii)A sinusoidal carrier wave has frequency 500 kHz and amplitude 6.0 V. It is to be
frequency modulated by a sinusoidal wave of frequency 8 kHz and amplitude 1.5 V.
The frequency deviation of the carrier wave is 20 kHz V^–1
Describe, for the carrier wave, the variation (if any) of
1. the amplitude,
2. the frequency.
thanks dear ..1. In frequency modulation, amplitude doesnt change!
2. When the signal is negative, the frequency lower limit is 500 - 30 Hz= 470 Hz
When signal is positve, the frequency is 500 + 30 Hz = 530 Hz
The frequency of the modulating wave means that the frequency changes from the upper limit to the lower limit to the upper limit again is 8000 times per second!
Solve Q11 Novemeber 2009 qp_42 , you will understand better.
Conducting diode?
the ms doesn't specifically say which ones are correct.
are those I circled the correct ones?
i would suggest you that an awesome explanation on this question is given in mike crundell.. Its exactly the sane question just values are diffrent.. have a look at itAnyone who can explain me this.. ??

Q1 c part 1 (Electric field)
Q2 b part 3 (complete the table)
IT should be like as shown in my attachment.Can you please check whether this is correct?
s02 £View attachment 8767 6 (I/t and induced E/t graph)
but according toIT should be like as shown in my attachment.
It was an April Fools' video.but according to0.999 = 1
so which video is correct? :S because they both seem to contradict each other.
IT should be like as shown in my attachment.
its that e.m.f is -ve d(phi)/dtThanks but what is the concept behind it??
thanks brother....t.here was one question in which i cnsidered it to be heavy bt ms said light....bt now understtodd that heavy means no oscillation will occur after force is appliedGuys this link will help you with different types of damping. especially Q2a ii) June 2012 qp_42. Only light damping is in our syllabus I guess.

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
