see i wud suggest do waves n thermodynamics...these r quite easy topics n r important too...as fr s-block frgt it as its all mugging up n maz to max 2 quesns will come on them...fr conics atleast do the basic formula cause its abt 20-30%percent//

no it wnt do shm as it is not mentioned about the magnitude and duration of force ..if it was a small displacement then yes there would be shm whose time period can be found out using t=2*pi*rt(I/mgl),...

hi...see first of all i feel tht the disc will nt rotate untill there is an external torque...now since the only force tht is present tht will provide torque is tension which will act only after the string gets taught....so as soon as the string gets taught the angular velocity shud be 0...so pls. explain tht y r u all applyin energy conservation...pls. correct me....

see the law of conservation of momentum is applicable when the other forces such as gravity, normal reaction etc...are negligible compared to the Force of impact acting due to the collision...so in this case if the rod is horizontal and the ball strikes on it vertically then certainly momentum will NOT be conserved as at the time of striking if u draw the FBD u will see that .... Fimp + N = MG which implys tht MG is comparable to impact force...nudge me for any further dbts...n rate if usefull...

i wud lyke to corect vivek here...it is not necessary that gamma shud have specific values as u have given..if the given sample is a mixture of gases gamma can have any value which could be 2/7 as in the above process......and certainly solution given by gaurav is perfect...and btw for more clarification refer to HCV part 2 - thermodynamic processes...

hi...bets of luck for ur prep.....see listen...1st join a good coachin insti or at least take up a correspondence course(i recommend VidyaMinder Course)....then set sum standard books to follow fr each subject...FINALLY MOST IMPORTANT...just shut up AND SIT DOWN TO STUDY...STOP THINKING ABT NETHING ELSE....

The JEE is for entrance to the seven IITs, IT-BHU, Varanasi and ISM, Dhanbad, six new IITs started last year and the two new IITs to be started from this year.

The core pattern of the JEE has been kept same and will consist of two papers of three hours duration each.

The eligibility criteria has remained the same as last year. You can attempt JEE only twice and consecutively and also should not have taken admission in any of the IITs.

To get more details about JEE 2009 visit the official JEE-2009 site. Download the brochure here.

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
in the 1st one fourth cycle the capacitor gets charges as the potential is increasing in the +ve direction., hence draws energy...in the in the next one-fourth cycle the potential acoss the capacitor(which is already charged to the max potential in the 1st quarter) starts decreasing and hence the capacitor starts discharging providing energy to the circuit..

please explain ur questions ....r u sharing them or are they a doubt.???but anyways for ur above question ...the above is only possible in AC voltage as .....I=V*2*pi*frequency*C

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
accd to me the answer is rite cause in AC circuit inductive reactance also plays a role(i.e. 2*pi*frequency*L) so across AC it will have a higher potential drop..so for the load resistence the potential drop would be lesser..
