An experiment is performed in the lab, where the mass and the volume of an object are measured to determine its density. Two com
pletely 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
d. the same within the uncertainty of each measurement method
Explanation:
The density of an object and in general any physical property, has the same value regardless of the method used to measure it, either directly or indirectly. Since two completely different valid methods are used, the results must be the same, taking into account the level of precision of each of the methods.
The stake, height and tether length of the tent form a right angle triangle where the tether length is the hypotenuse. Applying Pythagoras theorem: length² = height² + (stake distance)² length = √(8² + 2²) length = 8.5 feet
