Question

PLEASE HELP AND HURRY! VERY IMPORTANT TEST

1. What physical properties can cause an object to resonate?
-mass, color, and density
-shape, temperature, energy
-shape, composition, and length
-color, density, and composition

2. Which statement about resonance is correct?
-Resonance causes the amplitude of vibrations to decrease.
-Resonance causes the amplitude of vibrations to increase.
-Resonance does not affect the amplitude of vibrations.
-Resonance causes frequency to incease

3.How can you make the natural frequency of a string increase?
-decrease the tension of the string
-cut the string
-tighten the string
-loosen the string

4. A student wants to make the natural frequency of a tube increase. How can the student accomplish this?
-Decrease the length of the tube
-Change the composition of the tube
-Make holes in the tube
-Increase the length of the tube

5.Which factor determines the natural frequency of an object?
-color
-elasticity
-length
-pressure

Answer 1

The properties that can lead to resonance include shape, composition, and length. Resonance increases the amplitude of vibrations, and increasing the tension or decreasing the length of an object can raise its natural frequency.

Step-by-step explanation:

Resonance is a phenomenon in physics where an object vibrates with increasing amplitude when subjected to frequencies that match the object's natural frequency. Here are the answers to the student's questions:

1. Physical properties that can cause an object to resonate are shape, composition, and length.
2. The correct statement about resonance is that it causes the amplitude of vibrations to increase.
3. To make the natural frequency of a string increase, you should tighten the string.
4. To make the natural frequency of a tube increase, the student should decrease the length of the tube.
5. The factor that determines the natural frequency of an object includes its elasticity and length.
