Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Speed Practical Report Aim – To determine if different forms of movement for the same distance will affect the average speed. Hypothesis – Moving in different directions will affect the average speed because there are different actions involved in running‚ jumping and grapevines. Jumping involves a longer motion which will take the longest time because a jump covers the least amount of distance per second meaning a slower average speed. Running will have the fastest speed because this takes the least

Systems of linear equations‚ or a set of equations with two or more variables‚ are an essential part of finding solutions with only limited information‚ which happens to be exactly what algebra is. As a required part of any algebra student’s life‚ it is best to understand how they work‚ not only so an acceptable grade is received‚ but also so one day the systems can be used to actually find desired information with ease. There are three main methods of defining a system of linear equations. One

Assignment ( ECO 401 ) 1. Answer to part a. As the market clearing level is the quantity supplied equal to quantity demanded. Formulas Qs = 12000 + 50P Qd = 52000 - 30P Qd = Qs-----------------(1) Putting values in the above equation we get‚ 52000 - 30p = 12000 + 50p 52000 - 12000 = 30p + 50p 40000 = 80p P = 500 Clearing level of price (P) = 500 Clearing level of quantity (Q) = 52000 - 30P = 52000 - 30(500) Clearing level of quantity (Q) = 52000 - 15000
