But all properties of lights can't be explained believing light as wave . . . So how can we be sure that light is nothing just waves! Waves are non traveling on the other hand particles do travel so they can't be wave, can they? how they both can happen at a time when they r diffrent! One must...
v = \epsilontrans/ \epsilonaxial
where
ν is the resulting Poisson's ratio,
\epsilontrans is transverse strain
\epsilonaxial is axial strain
and Poissions Ratio have range and its not more then 0.5 and not less then -1?
so my question is how its value can turn "-1"?
As...
What argand diagrams really are ? Is there any difference between graph and argand diagram?
For complex number i is a sign that is count as \sqrt[]{-1}
Then why the point for a + ib would be (a, b) in argand diagram ?
That means, x = real part = a
y = imaginary part = b
so if i want to...
Thanks thanks thanks i have solved the problem !
When we divide one vector with its magnitude we get a UNIT VECTOR so \hat{n} = \stackrel{\rightarrow}{A}/|\stackrel{\rightarrow}{A}| and this unit vector must be parallel to \stackrel{\rightarrow}{A}.
So we divide one vector with its magnitude...
Yes, if P (3,4) then\stackrel{\rightarrow}{OP} = 3\hat{i} + 4\hat{j}
so parallel unit vector of \stackrel{\rightarrow}{OP}, would be \stackrel{\rightarrow}{OR} = \stackrel{\rightarrow}{OP}/|\stackrel{\rightarrow}{OP}|
=(3\hat{i} + 4\hat{j})/\sqrt[]{3^2 + 4^2}
=(3\hat{i} + 4\hat{j})/5...
What PARALLEL UNIT VECTORS are and Why i got to divide a vector with its value to get a PARALLEL UNIT VECTOR ?
This way
\hat{a} = \stackrel{\rightarrow}{A}
/|\stackrel{\rightarrow}{A}
| ?
I am sure that the answere would be very easy but i am such a . . . ! Please help!
Suppose you are standing on planet Earth now the apple is falling down on your head freely. Then its force should be F = mg OR GMm/(r - h)2
where, m = mass of apple
M = mass of Earth
r = distance of apple from Earth
h = your height
when this apple will fall on the surface of head it...
Again ! What will make this sense in them ? They are illiterate! (according to BANGLADESHI govt 45% is literate but i don't think so it crossed 35%) They don't familiar with BIRTH CONTROL and also have sm religious misconception superstitions blah blah blah which stops them taking steps against...
though i aint talking about INDIA! India is richer! . . . 50 % child marriage happen in India its almost 60-70% child marriage of the world! And the rate of killing fetus after identifying female child is very very high . . . And the thing i don't like about INDIA is discrimintion between CITY...
Dear bro! Things are n0t like that easy what are you thinking ! As i live in a 3rd worlds country so i know !
For example if that girl's parent is very poor and not capable to bear her mouth what they should do with that 8 yr old child ? Let her die deprive of food ? Or its better to give her...
