protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called ions. H would be a neutrally charged hydrogen atom‚ while H- would be a negatively charged hydrogen atom. H+ would be a positively charged

Case Study 12.31 and 12.32 This paper addresses the solutions to Case Study 12.31 and 12.32 in the textbook authored by David Marshall‚ Wayne McManus‚ and Daniel Viele “Accounting; What the numbers mean.” Both case studies bring about a better understanding of operating and financial leverage. This discussion includes the return on investment‚ return on equity‚ contribution margin‚ and break-even point. All these terms associate with the two types of leverage. The exertion of a force that

For example‚ the ancient Babylonians used 60 as their base. The Mayan Indians of Central America and Mexico used 20. In this section we consider bases other than ten‚ but we use the familiar HinduArabic symbols. We will consistently indicate bases other than ten with a spelled-out subscript
