thanks pmb phy

:confused: hi guys could some one explain what this means when a particle moves in an attractive central force field with a potential energy function V(x) = -k/r, for a gives non-zero value of angular momentum, at a certain time there is a minimum energy for which,it is possible to...

could someone please help me out here... I'm preparin for an entrance exam

thanks guys...

how does the speed of sound vary with temperature in an ideal gas? how do we derive this relation?

a planet moves around a star. (mass of planet << mass of star). the star undergoes a supernova explosion and loses 20% of its mass. the explosion does not directly affect the motion of the plant at that instant. how would this change the angular momentum of the planet ant the shape of its orbit...

what is the relation between the electric and magnetic field ? if the electric field vector is e = E exp[i(kx-wt)]j what is the magnetic field vector?
