Question

A sound has a higher pitch than a bell. Which quantity must also be higher in this sound than in the bell?(1 point) Responses frequency frequency wavelength wavelength speed speed amplitude

Answer 1

[AI-generated answer — Bot GPT 3.5]

The correct answer is frequency. Since pitch is directly related to frequency, a sound with a higher pitch will have a higher frequency compared to a bell.

Answer 2

Which statement regarding sound traveling in air is correct? (1 point) Responses The frequency of a sound does not affect the speed at which it travels. The frequency of a sound does not affect the speed at which it travels. A loud sound travels faster than a quiet sound. A loud sound travels faster than a quiet sound. A wave with a shorter wavelength is always faster than one with a longer wavelength. A wave with a shorter wavelength is always faster than one with a longer wavelength. As the wavelength increases, the frequency also increases

Answer 3

[AI-generated answer — Bot GPT 3.5]

The correct statement is: The frequency of a sound does not affect the speed at which it travels.

The speed of sound in air is primarily determined by the temperature of the air, not by the frequency of the sound. This means that sound waves with different frequencies can travel at the same speed in air.

Answer 4

Which statement about the effect of temperature on the speed of sound is correct?(1 point) Responses As temperature increases, the speed of sound increases because the medium becomes denser. As temperature increases, the speed of sound increases because the medium becomes denser. As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently. As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently. As temperature increases, the speed of sound increases because molecules in the medium collide more frequently. As temperature increases, the speed of sound increases because molecules in the medium collide more frequently. Changes in temperature have no effect on the speed of sound.

Answer 5

[AI-generated answer — Bot GPT 3.5]

The correct statement is: As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.

As temperature increases, the molecules in the medium have more kinetic energy and move faster, leading to more frequent collisions and higher speed of sound propagation.

Answer 6

Which forms of electromagnetic radiation are arranged in order of increasing energy? (1 point) Responses microwaves, infrared, ultraviolet, gamma rays microwaves, infrared, ultraviolet, gamma rays gamma rays, ultraviolet, microwaves, infrared gamma rays, ultraviolet, microwaves, infrared infrared, gamma rays, microwaves, ultraviolet infrared, gamma rays, microwaves, ultraviolet microwaves, ultraviolet, infrared, gamma rays

Answer 7

[AI-generated answer — Bot GPT 3.5]

The correct arrangement in order of increasing energy is: microwaves, infrared, ultraviolet, gamma rays.

This is because the energy of electromagnetic radiation increases with increasing frequency, and in the electromagnetic spectrum, microwaves have the lowest frequency and energy, while gamma rays have the highest frequency and energy.
