1. Mr. Ure has a mass of 65 kg, due to the fact that he is WAY too skinny! What is the force of Earth's gravity on him? 2. The force of Earth's gravity on a car is 3,050 Newtons. What is the car's mass in kg? 3. Mr. Rees has a mass of 90 kg.

Given only one 35 and one 50 resistor, list all possible values of resistance that can be obtained. (Give values in ascending order. Enter 'none' in all remaining unused answer boxes, if any.)

When heat is removed from a gas the gas will eventually A freeze B condense C sublimate D evaporate

A rod of mass M and length L can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m, moving with speed V, strikes the rod at angle θ from the normal and sticks to the rod after the collision.
