Question

natural frequency and resonance
what physical properties can cause an object to resonate?
○ shape, composition, and length
○ color, density, and composition
○ mass, color, and density
○ shape, temperature, energy

Explanation:

Resonance occurs when an object is driven at its natural frequency, which is determined by physical properties that affect its vibrational characteristics. Color, temperature, and energy do not influence an object's natural vibrational frequency. Shape, composition, and length directly impact how an object vibrates and its natural frequency, enabling resonance when exposed to matching external frequencies.

Answer:

shape, composition, and length
