An experiment is performed in the lab, where the mass and the volume of an object are measured to determine its density. Two completely different valid methods are used. Each experimental method to measure the density is performed, two considerable sets of data are taken on each and the results are compared. The results of the density measurement by each method should be:.
a. dependent on the mass and the volume of the object
b. completely different, because it was measured different ways.
c. correct on the most accurate method and wrong in the other
d. the same within the uncertainty of each measurement method
