(Subject: Chemistry & Physics) Please answer all questions. Please be clear. Short answers are fine. 3-4 sentences.

1) If a feather and a lead ball are dropped from 1000m in AIR (vacuum) , will they hit the ground at the same time? Why or Why not? Recall that in a vacuum, the acceleration due to gravity is the same for all objects. (i.e. acceleration due to gravity on earth is g = 9.8 m/s^2

2) List the three principal types of chemical bonds in order of strength with the strongest first. Please include a short description of each and an example of each.

3) If you have a cup of oil (non polar) and a cup of water (polar), and a cup of an unknown substance, how can you tell if the unknown substance is polar or non polar?
