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...

Thankuuu ^.^

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...

Thanku :)

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...

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

hello :) Homework Statement (Q)A 20 cm long capillary tube is dipped in water.The water rises up to 8 cm . If the entire arrangement is put in a freely falling elevator, the length of water column in the capillary tube will be <a>8 cm <b>6 cm <c>10 cm <d>20 cm Homework Equations...

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"...

>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...

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 :-...

lol . I missed that xD Thanks abdul :) Got it ^.^

All the physical quantities of interest can be derived from the base i.e. fundamental quantities [mass,length and 5 more].By dimension of a quantity[Q let] in a base quantity, we mean "the exponent of a base quantity that enters into the expression of that qunatity[Q]". Eg:- Force = mass *...

hiii :) Homework Statement (Q)Air is pushed into a soap bubble of radius r to double its radius.If the surface tension of the soap solution is S, the work done in the process is <a>8(pie)(r)2(S) <b>12(pie)(r)2(S) <c>16(pie)(r)2(S) <d>24(pie)(r)2(S) Homework Equations Surface energy...

heya :D Homework Statement (Q)Water rises in a vertical capillary tube upto a length of 10 cm. If the tube is inclined at 45 degrees, the length of water risen in the tube will be <a>10 cm <b>10/(2)1/2 <c>10(2)1/2 <d>None of these Homework Equations Height raised in capillary, h =...

hellO :D Homework Statement (Q)A large cylindrical tank has a hole of area A at its bottom.Water is poured in the tank by a tube of equal cross-sectional area "A" ejecting water at the speed "v". <a>Water level in the tank will keep on rising <b>No water can be stored in the tank <c>The...
