Chapter U4.75, Problem 5E

Interpretation Introduction

Interpretation:

From a set of samples, one containing 740 tiny plastic beads and the other 740 marbles, the one with more mass needs to be identified.

Concept Introduction:

Mass is a fundamental property of an object which is representative of the amount of matter present in that object.

For small objects where the mass cannot be measured on an individual level, an average mass can be deduced by weighing the collection of similar objects and dividing by the total count.

Answer to Problem 5E

Sample with 740 marbles will have more mass

Explanation of Solution

It is given that sample 1 contains 740 tiny plastic beads and sample 2 contains 740 marbles. Both samples have the same count of items.

However, a single unit of marble will weigh more than a single plastic bead. As a result the collection of 740 marbles will have more mass than that containing equal number of plastic beads.

Conclusion

Thus, thesample with 740 marbles will have more mass.
