acceleration due to gravity at the Earth’s surface (g) g’ = (re2 / r2) g Acceleration due to gravity inside the Earth Here let r represent the radius of the point inside the earth. The formula for finding out the acceleration due to gravity at this point becomes: g’ = ( r / re )g In both the above formulas‚ as expected‚ g’ becomes equal to g when r = re.

Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms

Working out the Formula of Magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Apparatus Googles

having to choose an infant formula. Any trip to a local grocery can prove how difficult a task this can be. The questions these parents most likely would ask would be: is one formula better than another? Does brand name matter? Does "new and improved" or "enhanced" formula mean better? Are infant formulas really a safe and nutritious choice for feeding babies? The Federal Drug Administration (FDA) regulates over forty different brands and types of infant formulas in the United States.2 They
