Properties of Pure Substance: Unit 3
Applying energy balance to a system of interest requires
knowledge of the properties of the system and how the properties are
related.
The objective of this chapter is to introduce proper

Gravitation and Satellites 1
1. A satellite is in orbit 480 km above the earth's surface. Its period of rotation about the earth is
100 minutes. If the orbit is taken to be circular, calculate its linear speed. The m
