Question 179302: Suppose a rubber time looses a layer of one molecule thick from tis surface during each revolution on the pavement , (by molecule you should infer one monomer unit ). Assume that the molecules average 7.50 Angstroms in thickness ,that the tire tread is 35.6 cm in radius , and 19.0 in wide . On a 483 km drive from Cleveland to Toledo . (a)-how much is the radius reduced in mm , (b)what volume of rubber is lost in cm^3 from each tire . Please explain in detail , and can you suggest a web site on internet that would give me many conversions word problems that start on a simple side and gradually get harder . Signed Michael , thankyou very much .
