    Veloctiy of image of a moving obect having constant veloctiy

    If an object moves towards us with constant velocity, its velocity is constant with respect to us. But when we view its image in stationary car rear view mirror (or any stationary mirror), its velocity is changes? Why and How?

    Conductivity of metals at 0 kelvin?

    What is the conductivity of metals at 0 kelvin? i think it will be zero because at 0 k entropy is zero. Every motion is cease.

    Work Energy Theorem and total work

    Plz tell me Which is correct form of Work Energy theorem 1. Total Work = Toatl change in Mechanical Energy(Potental + Kinetic) 2. Total Work + Potential Energy = Total Change in Kinetic Energy 3. Total Work = Total Change in Kinetic Energy (Mention in the textbooks) Actually i am confused...

    Calculating Reaction Force: Box on Rigid Wall with Applied Force of 100 N

    Imagine a box of mass "M" lying on a surface and attached to a rigid wall too. Assuming that the co-efficient of friction between them(box and surface of ground) is "μ". and I am applying a force of 100 N horizontally on the box. So my question is how mush force is being applied by the wall on...

    How to proof that the electric fielf inside a conducting shell is zero

    how to proof that the electric fielf inside a conducting shell is zero ? i don't want to solve it using gauss law and not through practically taking example but i wanted to solve it through vector by finding the resultant zero at any point? please explain?

    What makes electron flow in an electrochemical cell

    1...if i take only one part of cell ... will the reaction Zn ----> Zn(2+) + 2e take place?? 2...if i just put the zn rod in zinc solution will the rod melt ? 3...if i will put a zinc rod outside a beaker containing copper sulphate solution and connect the rod and solution with a wire will any...
