  1. V

    Capacitor directly connected to a DC battery.

    HeyoO everyone (^_^) and Thanks for your time. Homework Statement This question is about the "intial" point of time i.e. as soon as the key is closed. Before the current starts to flow which charges the capacitor till the voltage of capacitor is equal to voltage across the battery. A...

    Water Level in Tank: Rising & Oscillating

    Thanks again :) Ok if i think like that i get the answer ^.^ But can we tell the velocity of fluid [using equation of continuity and bernoulli's equation]flowing out from hole if we start from the instant the tank is "empty" and then, the water is poured in ?? Oo[Not from the instant when water...

    Water Level in Tank: Rising & Oscillating

    Hehe I know that law :) But i can't see how to use it in this problem .As i wrote in previous post, i can't see any water level in the tank. And also i can't see that equation of continuity can be used here with the rate of water flowing from the tube and rate of water from the hole. As much i...

    Rise of Water in a 20 cm Capillary Tube

    Thanks :) One more question :- Will the hemisphere upwards or downwards?? Or it depends on capillary tube and the liquid taken??

    Water Level in Tank: Rising & Oscillating

    Thanks both of you :) --->But i still have problem ~.O I can't decide from questions language whether the tank had initially a water level or not. To me its appears to be Empty initially.So, as the pipe pours in some water , that water will spread out on tank's large bottom and there "will not"...

    What Is the Final Angular Velocity of a Rod After Being Struck by a Bullet?

    >Hmm this is what i thinks {I cud be wrong But u said to reply} :- -->Hmm in questions , the particle gets sticked or embedded means the same thing[as much i use myself in many questions]. >So u can use ur "sticking out its head" thinking and then "i us d formula of MI taking d body's MI...

    What Is the Final Angular Velocity of a Rod After Being Struck by a Bullet?

    hi abhi (^.^) >The place where you went wrong is in Calculating Moment of inertia. >Think again, didn't the formula you used to calculate M.O.I is used for "Uniform" rod .But the system we get after collision isn't uniform {check urself}. >If u agree with me, then i give you a suggestion :-...
