Full of jealousy, her neighbor, Rebekah, dropped a Cleveland 351 in her vintage 1965 Mustang (that's 351 cubie inches (in') engine size!). Who has the larger engine? What is the difference between the sizes? Please, use Dimensional Analysis for solution set-up and please show your work! L 5.91 L 27A Who has the larger engine? What is the difference? Sig.

Answer 1

thank you very much
32 (a) 69,6005 – 6.9600x104s (6 0.0001200nt= 1.2x10-4 mod C 1,000,000,000 (d = 1 x109 cd (d) 34,000 lbs = 3. 4X10 lbs S . . . Thank hope this will help you . good luck . . . . . . . .

Working the solution for Shally volume of engine = 5.4L for Rebekah volume of engine = 351 in (5.751837L] or 5.8L 1 inch = 2.54 cm first convert the measurment to Cubic measurment 1 Cinch) = (2.54 cm) 1 in3 = 16:3073 • Second Convert to Cubic Centimeters Set up the Convession so that the desired unit will be Canceled out Volume in cm3 = (volume in in3) X (16.387 m3/13) volume in ein = (351x 16.307) cm3 Volume in cm3 = 5751.837 cm3 Third 12 = 1000 cm3 1 cm3 = 1 , volume int = volume in and the 1000ch 5751-037 Cm3 (1000x5751-831) 4 = 5.751837 L who has langer engine Rebekah.. What is difference 5.0 - 5.4 = 1000 (0.4L
