In Parker 'O' ring handbook, Dichomatik 'O' ring handbook & Eriks 'O' ring handbook Stretch limit given as 5% maximum. However, I tried to contact so many industries from last 3 weeks & finally I find one which gives me desirable tolerance which I required. So, my problem is solved...
It may seems like simple homework question but it is industrial question with actual condition & I am struggling for the answer & also asked this question on other website but not get any reply. So ,please help me
'O' ring Internal Diameter(ID) ID=4 mm with tolerance is + & - 0.15mm...
Plank length puts limit on the smallest dimension which is 1.616×10^-35 Meter. Nothing can be smaller than this. Plank length is 10^20 times smaller than proton diameter.

if we were so far away from sun that the average Earth temperature drops & as it attain 90 K, oxygen start to liquefy, as 90 K is boiling temp. of oxygen at atm. Pressure.
To calculate distance so many assumptions are required.
Take only sun as a source of energy for earth, no other source...
To convert oxygen into water at atmospheric temperature 300 K, pressure required is 5 GPa or 5000 MPa. See link http://en.citizendium.org/images/thu...se_diagram.png
Atmospheric pressure is 0.1 MPa. So, 50,000 times more pressure is required to convert oxygen into liquid. So it is required to...

OK, it required force to pull apart & this additional energy which I give plate to pull apart is giving higher increase in temperature then theoretical calculation in which I only take electrical energy for calculation of rise in temp.
thank you.
Case:1 I have one iron spring. I compress it gives potential energy E= ½* K*x2 & bind it by glass wire which is not melted in acid. Now I put this spring in acid & it melted completely, So where the potential energy gone?
Case:2 I put one magnet in glass vessel & hold it in vessel by some...
This means that boiling water possesses higher mass then cold water by extremely small amount which is neglected for practical purpose.
OK, Thanks for giving answer.
This is question about equation E=m*c2. Why this equation does not required any condition of matter?
Case 1: I take two mole (4 Kg)H2 & one mole(32 Kg)O2 & make water & get energy.
2H2 (4 Kg Hydrogen)+O2 (32 Kg Oxygen)=2H2O(36 Kg of water)+ 572 KJ Energy
Now I convert this water into energy...
Hello pallidin,
If two magnet put in such a manner there is repulsion is acted between them, then lines of magnetic force of both magnet is in opposite direction, this leads lost in magnetism. That's why magnetism became weaker.
I have heard this thing before if anything is wrong in this...
Two magnet I put nearer to each other in such a way that there is a repulsive force between them. Both the magnets have some potential energy with respect to each other. I keep magnet in this position for a long time & so magnetic field became weaker & so magnet have less amount of potential...
