Hi Sabyasachi,

Newton's formula is an alternate formula for finding image distance for a lens

For this one needs the distance of the object and image w.r.t. focus. Let us say that object is a distance 'x' away from F and image forms a distance 'y' away. So, the Newton's formula is f2 = xy

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
