Chapter 01 - Introduction1-23
Chapter 01 - Introduction67. Acceleration has dimension [L/T2]. Use dimensional analysis to determine the ratio ofaccelerations for car A to car B, if car A travels a given distance in half the time required bycar B.2
Section: 01.06 Dimensional Analysis68. Consider the ratio of the surface area of a cylinder to its volume. Assume the height isequal to its diameter. What happens to this ratio if the diameter of the cylinder decreases by afactor of 2?A.Remains the sameB.Decreases by a factor of 2C.Increases by a factor of 2D.Decreases by a factor of 4E.Increases by a factor of 4
Section: 01.06 Dimensional Analysis69. Consider the ratio of the surface area of a sphere to its volume. What happens to thisratio if the diameter of the sphere increases by a factor of 3?
Section: 01.06 Dimensional Analysis1-24
Chapter 01 - Introduction70. You can reason that the time required for a ball to fall is related to the height from whichit falls and to the acceleration due to gravity. Time is measured in seconds, height in meters,and gravitational acceleration. Using dimensional analysis, determine how the time to fallfrom height h compares to the time required to fall from height 2h.
