7. Determine the WEIGHT of a 50-kg person that is moving at a speed of
14 m/s.

How to tell if a molecule is polar or nonpolar with electronegativity

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

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)
