Equivalent resistance
I don't understand how the circuit will be simplified here. Please give a solution for this.
Rotation 2
We can only write v = rω when we take moment of inertia about the axis which is at rest at an instant, for pure rolling round bodies, we should only be able to write it if we take acis about it's point of contact with the rough surface where it's pure rolling...
In this question, why is the moment of inertia taken about the axis through the com and still v = rω is used?...
Rotation
Why can we not do this while energy conservation?
mgh = 1/2 mv² and the put v = rω
doing mgh = 1/2 Iω² gives the right ans (15)...
Wave optics
Whats wrong in my approach? My answer ain't matching, sorry for the pathetic handwriting.
NLM Weow Qoschun
1. Kya 2m par spring force act karega at the instant when 3m is released?
2. Would the acceleration of 2m and 3m at the instant 3m is released the same or would they be diffrent (upar wala point hi repeat kar gaya lol but yes genuine concern hai)...
Electricity doubt
I tried using KCL and Ohm's Law but still couldn't solve this. Please give me a detailed solution for this question.
NLM Qoschun
I tried going thru the scan solution but honestly it stopped making sense after applying Momentum
Ionic
Ques 2
Acc to me naoh + h2co3 will be carried out first but the product should be na2co3 or nahco3
Also , why do we assume complete dissociation of h2co3 in such cases...
