Mass of Pennies: Exploring the Relationship Between Mass and Quantity

Is the combined mass of 20 pennies equal to 20 times the mass of a single penny? Provide an explanation for your answer.

Option A. Yes

Option B. No

Answer:

Option A. Yes

Yes, the combined mass of 20 pennies is generally equal to 20 times the mass of a single penny, assuming the pennies are identical.

This relationship is based on the concept of mass as a scalar quantity that directly adds up. When you have multiple identical objects, you can determine the total mass by multiplying the mass of one object by the number of objects.

For example, if one penny has a mass of 2.5 grams, the combined mass of 20 pennies would be expected to be 50 grams (2.5 grams x 20). This assumes that each penny has the same mass and there are no significant variations.

Although in reality, there may be slight variations in mass due to manufacturing differences or wear and tear over time, the general principle holds true that the mass of 20 pennies is approximately equal to 20 times the mass of a single penny.
