Question 20

A student claims: “Doubling the amplitude of a mass-spring system will double its period of oscillation.”

Which of the following correctly evaluates the student’s claim?

Which of the following correctly evaluates the student’s claim?

Accepted Answer

Answer

The claim is correct because more water mass acts on the wider base, increasing pressure.

Answer

The claim is incorrect because pressure at a given depth depends on fluid density and depth, not on the shape or base area of the container.

Answer

The claim is correct because the total downward force on the bottom is greater in Container X.

Answer

The claim is incorrect because Container Y has higher pressure due to the more concentrated fluid column.
