Date of Experiment: February 5‚ 2013 Report Submitted: February 11‚ 2013 Title: Laboratory Techniques and Measurements Purpose: To gain knowledge about the International System of Units and use it to determine volume‚ mass‚ length‚ and temperature. To learn to use these forms of measurement to determine density and concentration‚ as well as learning basic lab equipment to create dilutions. Procedure: Part 1: After reading the various information given‚ I gathered different

graphing‚ or tables. Show all work. 1. The length of a rectangle is 7 meters more than the width. The area is 60 square meters. Find the length and width. Let x=width and x+7=width A=lw 60=(x+7)(x) 60=x²+7x x²+7x-60=0 (x+12)(x-5) x= -12 x=5 x must equal 5‚ since the -12 solution doesn’t make sense. A side cannot have negative length. The width is 5 meters and length is 12 meters. 2. A picture frame is 18

Stride Rate and Length Although strides vary greatly among runners‚ a few studies have worked to quantify differences in stride rate between barefoot and shod runners. They have concluded that an elite shod runner usually has a stride frequency between 170-180 steps per minute even at low speeds such as 2.75 m∙s-1. On the other hand‚ nonelite runners often fall in the range of 150-160 steps per minute at similar speeds. Barefoot or minimally shod runners are often characterized by shorter strides
