A biconvex lens made of  a transparent medium of n=1.5 is immetrsed in a medium of n=1.33.will the lens behave converging or diverging?give reason.

Since the Biconvex lens is placed in another medium of μ = 1.33, the effective refractive index of medium of lens is 1.5/1.33 = 1.128.
Since effective refractive index > 1, this Biconvex lens will behave like converging lens

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?
