Jupiter is 318 times more massive than Earth. Based upon mass alone (i. e, if you were to place Jupiter at the same distance from the Sun as Earth), what would be the gravitational force between Jupiter and the Sun in units of "Earth-pulls?"

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)
