Section 1.4—Converting Units Often‚ a measurement is more convenient in one unit but is needed in another unit for calculations. Dimensional Analysis is a method for converting between units. Equivalents Dimensional Analysis uses equivalents. What is an equivalent? Two measurements that have the same meaning. Ex: What happens if you put one over the top of the other? See your reference sheet for some common equivalencies. We can use these conversion

Each Sandwich Blitz location is situated on very small parcels of land. This original strategy has contributed to somewhat lower operating expenses for the business and both Dalman and Lei view this as a competitive advantage. Based on new local health codes‚ new laws have been issued requiring trash dumpsters be a minimum distance of 30 feet (9.144 meters) from the rear entrance of the building. New land-use laws require that all out buildings be at least 6 feet (1.8288 meters) from the property

Introduction: Aim: To find the relationship between the length of a simple pendulum and the period of oscillation. Research question: How does the string length of the pendulum affect the period of oscillation? Prediction: The longer the string‚ the longer it will take to make one complete oscillation. Variables: Independent variable: Length (L). Dependent variable: Period of oscillation (T). Controlled variable: Mass of the plasticine. Tools & Materials: Stopwatch. Ruler. String. Plasticine

moles-stoichiometry-practice-problems Now you’re ready to use what you know about conversion factors to solve some stoichiometric problems in chemistry. Almost all stoichiometric problems can be solved in just four simple steps: 1.Balance the equation. 2.Convert units of a given substance to moles. 3.Using the mole ratio‚ calculate the moles of substance yielded by the reaction. 4.Convert moles of wanted substance to desired units. These "simple" steps probably look complicated at first

A polymer is a substance formed by many molecules that are all strung together to form a long chain‚ and has been around since the beginning of time (Polymer). Examples of different polymers being used in everyday life are things like rubber and starch‚ which are both frequently used in the world (Brewer). Polymers also make up what are known as “polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both

CAREY FOSTER BRIDGE Introduction The Carey Foster bridge is an electrical circuit that can be used to measure very small resistances. It works on the same principle as Wheatstone’s bridge‚ which consists of four resistances‚ P‚ Q‚ R and S that are connected to each other as shown in the circuit diagram in Figure 1. In this circuit‚ G is a galvanometer‚ E is a lead accumulator‚ and K1 and K are the galvanometer key and the battery key respectively. If the values of the resistances are adjusted so
