Question

A tall measuring jar contains ethyl alcohol of density 0.8 gm/cm^3.An iron ball is dropped into it and the level rises by 20 cm^3 . The buoyant force acting on the ball is

Answer 1

Answer:

energies of orbitals the energy of an electron in a hydrogen atom is determined solely by the principal quantum number does the energy of the orbitals in a hydrogen atom increases as follows one as is smaller than 2x is equal to 2 p.m. is a smaller than three years is equal to 3 p is equal to 3 x minus 4 is equal to 4 is equal to 40 is equal to four is smaller than 2.3 and is depicted in figure 2.16 although the shapes of 2S and 2P orbitals are different and electron has the same energy when it is the it is in the 2s orbital as when it is present in 2P orbital the orbitals are having the same energy are called degenerate
