a) Photovoltaic solar power systems are environmentally beneficial because they release no harmful pollutants or emissions such as CO2. These systems operate throughout the day‚ implying it is sunny‚ and do not rely greatly on other power sources to operate‚ thus there is less of a toll on the environment in terms of external resource usage. An environmental cost of photovoltaic systems is the manufacturing of these systems that uses energy and could possibly contribute to more atmospheric pollution

The Size of the Solar System Overview • Become familiar with the scale of the planets vs. their distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that‚ say‚ the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible)‚ however‚ to picture this distance in the human mind. In this exercise‚ we will learn to access the often unpalatable distances encountered in astronomy
