Dimensional analysis: 1.35 kilometers per second= 3019.86 miles per hourFurther explanationDimensional analysis, also known as factor-label method or unit-factor method, is a method used to convert one unit to a different unit.Dimensional Analysis is a very basic aspect of measurement and has many applications such as in applied physics.There are seven steps to do dimensional analysis:Identify the starting factor.Identify answer units.Determine conversion factors needed.Ensure the conversion factors are in the correct format.Cancel units that appear in both the numerator and denominator.Simplify the fractions.Solve.1.35 kilometers per second= ? miles per hourSo first we identify the starting factor:1.35 km/second * 0.621 miles/km = 0.838 miles/sec (the km cancel out)Next, we need to convert from seconds into hours. There are 60 second in a minute and 60 minutes in an hour, so there are 60*60=3600 second/hour. Thus,0.838 miles/second * 3600 second/hour = 3019.86 miles/hour.Learn moreLearn more about example of dimentional analysis solutionbrainly.com/question/4993038Learn more about uses of conversion factorsbrainly.com/question/1851807Learn more about miles per hourbrainly.com/question/1763271Learn more about dimentional analysis in bicyclebrainly.com/question/8086790Answer detailsGrade: 9Subject: Advanced Placement (AP)Chapter: Dimensional analysisKeywords: Dimensional analysis...
