Question

which factor determines the natural frequency of an object?

○ pressure

○ elasticity

○ color

○ length

Explanation:

Natural frequency is an intrinsic property of an object, determined by its material's stiffness (elasticity) and mass distribution. Pressure is an external condition, color is an optical property, and length alone does not determine natural frequency without considering material properties. Elasticity directly relates to the restoring force that drives the object's natural oscillatory motion.

Answer:

○ elasticity
