in a series LCR circuit to an ac source of variable frequency and voltage v= Vm sin ωt , draw a plot showing the variation of current (I) with angular frequency (ω) for two different values of resistance R1 and R2 (R1 >R2).write the condition under which the phenomenon of resonanceoccors. for which value of the resistance out of the two curves, a shaper resonance is produced ? define Q-factor of the circuit and give its significance

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

That big glowy thing in the sky is called the sun

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
