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

A solar inverter‚ or PV inverter‚ converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequencyalternating current (AC) that can be fed into a commercial electrical grid or used by a local‚ off-grid electrical network. It is a critical component in a photovoltaic system‚ allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays‚ including maximum power point tracking and anti-islanding protection

metric system! Does the United States use the metric system? Nope! America is that stubborn 5 percent that refuses to conform‚ allowing needless mistakes to happen. The metric system was carefully fashioned with a logical‚ systematic pattern; whereas‚ the United States customary system is a hodge-podge system of measurement based off of the old English system.

The Muscular System Teacher pages The muscular system allows us to move. Adults have a certain fixed number of muscle cells‚ approximately 602. . Through exercise‚ such as weight lifting‚ the cells enlarge but the number of cells does not increase. Structure and Function There are three types of muscle tissue—smooth‚ skeletal‚ and cardiac. Each has its own distinctive function‚ and therefore‚ its own distinctive structure‚ but all muscles allow movement of some kind. Skeletal Muscle

The function of the cardiovascular system The Cardiovascular system circulates oxygen and nutrients to body cells and tissues. It also allows for removal of carbon dioxide and wastes from those cells and tissues. The cardiovascular system delivers hormones to targeted tissues‚ maintains body temperature‚ and helps defend the body. The cardiovascular system is made up of the heart‚ blood and blood vessels. The heart is the pump of the cardiovascular system. It consists of 4 chambers‚ which is

INTRODUCTION When thinking of starting a contracting business for solar panels‚ many economic issues and concerns play a factor in the decision making process. Having a concern for the environment and knowing that solar panels have a cost saving for both households and business seems to be reason enough to start a business. However‚ before making such a financial investment you should first take a look solar panels in the economy in terms of (i) GDP growth rate‚ (ii) interest rates‚ (iii) level

What are bodily systems?- Bodily systems are basically default programmes within our body that pickup information from within or the external environment and trigger an automated response. For example if you were to run‚ your body would increase its heart rate to match the oxygen demand made by the muscles. This is done without thinking and it is made possible by how the brain has cleverly integrated with all the bodily systems‚ from the digestive system to the circulatory system. It is critical
