What are polar molecules
Polar molecules - molecules having of two or more atoms that are neutral but have a charge which is not distributed uniformly.
Assume a 55.0-kg ice-skater, who was initially at rest, fires a 2.50-kg gun. The 0.045-kg bullet leaves the gun at a velocity of 565.0 m/s. What is the velocity of the ice-
