I'm studying for the exam day after tommorow and while reading the practical on jaeger method I found the following...
r is the radius of the capillary tube
advantages of this method..,
•contact angle is not needed
•can find surface tension of liquids like...
1. I found this diagram on book but there weren't any description.can someone tell me, what its trying to tell specially by those two red lines meeting the ground at the same place...?
2.this is a diagram for siphon method of removing water. I have read somewhere that the siphon stops if the...
I am trying to figure out what happens here...and now I've stuck on this...
Here it goes....,
Both contact A with B and A with ground are rough
We increase the force P applied here from zero.When there's sufficiently big μs between A and B than that of A and ground,there's an...
I was reading an article about velocity and displacement of a particle..It says "though the position of a particle is a continuous function of time,velocity sometimes isn't.For instance velocity is not continuous while an impulsive force is being applied."
But I think that velocity changes...
Here's what I understand....
Types of errors
errors due to slow stopwatches
errors due to incorrectly graduated scales
error due to unevenness of the measuring item
Ways of comparing errors
Applying remainder theorem again and again to show that the remainder of the f(x) polynomial function when divided by (x-α)(x-β) is A(x-α)+B . Determine A and B
the remainder of a polynomial f(x), divided by a linear divisor x-a, is equal to f(a)
Find the limits of the following
We can't use L'Hôpital's rule as it's not in our syllabus.We have to use only
The Attempt at a Solution
I attempted a lot but can't find a way to solve these three (out of about 80 limits)
pls show me the...
I have seen that in some circuits there's grounding...I know that earthing is for keep a part of a circuit in a zero potential...Don't know why it's done...Here's some circuit's..Tell me why it's been earthed..
One end of a light elastic string having a natural length of 'a' and elastic modulus 'mg' is attached to 'm' mass and the other end to point 'O'. Then the mass is projected upwards.Where is the center of SHM?
An elastic string is attached to A on a horizontal plane and a mass is attached to the other side of the rope.Then the rope is pulled to C and release.It engage in SHM from C to B and D to E and so on
natural length = l
extension = a
max end points = E & C...
A light rod is hung by two wires having same length of 2m and the same young's modulus of 8\times1011Pa,but having different cross sectional areas of 1mm2 and 2mm2.
The wire having the cross sectional area of 1mm2,gets an increment of 2mm in length because of a temperature increment.But the...
