I was suddenly asked this question by a friend... How a 'cats & dogs' rain would affect the velocity of sound through air?(as we know velocity of sound through water is five times than in air) I just couldn't be sure how to answer it... The raindrops are really small but there's a lot of...

Thank you... :)

So if I slowly pull the A string first B string will tear apart... Cause the A string will expand and it will pull the mass and B string... So B string will reach its breaking weight before A... Cause B has an additional weight mg working on it.. But if I suddenly pull the A string,it will...

AT Yes,but we are doing another analogy to explain this analogy... I thought of it at first but assumed their could be another approach to explain this incident... It just seems so interesting to me... Dauto Yes... That's why we have to assume that the Earth is a uniform mass sphere...

The period of a satellite revolving around the Earth earth at surface height is equal to the period of any mass thrown through a hole of the earth(which gains a simple harmonic motion)... It seemed really interesting to me... Why both of these periods are same? T=2 π √(R/g)

Why aren't we using this method?

EEE --> Electrical & Electronics Engineering CSE --> Computer Science & Engineering http://www.buet.ac.bd/

I am now going to do my BSc in engineering in EEE or CSE... Now my question is what will be best for me... I have a good understanding of basic maths i.e. algebra,calculus,geometry especially combinatorics etc... To tell the truth combi has always been my favourite... But I find Physics to be...

Can you please find the current through 6V,10V & the 12 V battery here? That would really clarify things for me... And in case of solving the problem, I will use kirchhoff law... What I am asking is what happens exactly at first and what follows later?

Thank you...

Remember the F=qvB sin (theta) formula... The electrons in the wire will be pushed by the m field resulting in current flowing the opposite direction... As mfb said,there only has to a component of the m field perpendicular to the velocity...

Suppose I have 10.2 W power source... Now how many 1 W bulb can I use here? Obviously I can use 10 bulbs at their best here... But can I use an eleventh one? Usually we do it like this 10.2/1=10.2~10 but my ques is there is some power left here... So why can't we use one more? This will...

So do the two batteries in parallel averages each other out? (15+5)/2=10

I want to know how we can find out the net voltage of a circuit where two batteries with different voltages are connected in parallel... Let's consider the problem stated below... If I have a circuit where there are 2 batteries in parallel(5V & 15V)... And it is connected in series with...

Thank you very much for the discussion... :)
