    Post your Physics queries here ...

    K.E is greatest at mid point Yes and that point is often taken as reference for No. oscillation experiment ...

    Yes you are onto the point the new element is stable ...... Were does it get that electron ..... and i wasn't particularly taking abt selenoind just a peice of Cu wire... The baic reason is the magnetic feild and the electric feild are both related and part of somting bigger the electromagentic...

    ok Silly me i need to revise more... i have almost forgotten radioactivity lol ..., ok and yes that is what i meant wont it be an ion since it has gained an extra proton ? and why does current do that i know it a property but then why electrons generate the field?

    Molecules or particles moving further away is expanding right

    I Guess both Key concept for Kenetic Therory... Same can be applied for liquids In a solid, the atoms are very attracted to one another. The atoms vibrate but stay in fixed positions because of their strong attractions for one another. Heating a solid increases the motion of the atoms. An...

    Sorry what i ment was there will be NO resistence

    Ok thanks my question was what makes then penetrating rays ? Short wavelengths maybe ? They are ionizing b/c they are completely energy.... .. about the radatiton Question i ment how does the atom the dauther nuclide itself become stable if it has an extra proton so Electrons not equal to...

    Yes liquids expand they expand as much as the intermolecular forces can bear before escaping into gaseous state and they are poor conductors of heat.... Energetic liquid particles on the surface escape into a gas lowering the aveerage liquid temp ..and that is how evaporation works ... You water...

    Can Some one also answer this ..... We know that there in A/C circuitry there is live and neutral Wires in a switch board ... But have you noticed that when we plug in those two pin appliances you can really place then any way around...Doesn't Live and neural matter here .... There might be a...

    No problem you see the all the Current directly flows through the Fuse hence there is no resistance ... No resistance means the Fuse will have more current more going through it then it was designed for ... do like if fuse is 13 A No R means the Fuse has all potential difference across say and...

    Pressure definitely increases ... Molecules more and more with higher kinetic energies....The molecular distances should increase and would increase if it wasn't in an Enclosed container... The gas evenly spreads out and has occupies the volume OF the container and when the gass is heated the...

    Physics problem

    Alpha beta deflections in a an electric or magnetic field can be easily determined by the Fleming's left hand rule...Heat does not expand because there are strong forces between liquid particles and molecules and when these particles are energetic enough .. instead of expanding they escape into...

    Physics problem

    For the First Question when the metal case becomes live and the live wire is connected to the casing . The casing is live and if it is earthed The current directly flows from the live wire to the earth via the metal case. Now since the main circuit of the appliance is bypassed the resistance of...
