I think the answer is B. frequency

Ilya [14]2 years ago

Answer:

A

Explanation:

The property is amplitude. Sound waves are pressure waves, and the higher the amplitude, the higher the energy created, and the louder the sound is.

The pitch of a sound is determined by its frequency.

Pitch represents the quality of sound produced, not the amount of work done to produce that sound.

Frequency and wavelengths are the quantities used in determining properties of sound, not the actual properties

How do you solving kinematic equations for horizontal projectiles?
daser333 [38]
See projectiles are very simple unless you understand its core concepts....projectile is nothing just mixture of upward motion and horizontal motion....
THE KEY IS FORGET THE NAME PROJECTILE...ITS JUST HORIZONTAL MOTION + VERTICAL MOTION

chubhunter [2.5K]

Answer:

sound intensity is explained by the following formula I= P/A where I= sound intensity(W/m²),P=power(W),A= area(m²) I hope this helps good luck!

A science teacher gives a student four beakers, each with a different liquid inside. The table provided shows the volume of each
Ksivusya [100]

The dependent variable in this experiment is the mass of each liquid.

Density is the ratio of mass to volume of a substance. In this experiment, since the volume of each liquid is given, to get density, mass of each quantity must be known which is the outcome.

Density also depend on the mass of a substance and density can easily be identified by mass if all the substance in question have the same volume.

In this experiment, all the liquid have the same volume. Since the student want to list them in order from the least dense to the most dense, how dense the liquid are will be a function of the differences in liquid mass.

The least dense liquid will float. That is, will be at the top most of the container. While the most dense will be at the bottom of the container.

Therefore, the dependent variable in this experiment is the mass of each liquid

Answer:

Apply this to waves: count the number of waves passing each second (= frequency), and multiply by the length of each (= wavelength) to find the speed. speed = distance/time = l/T= l / (1/f) = f λ. Work through three examples: A simple example, perhaps for sound in air, with values in Hz and m.

Explanation:Apply this to waves: count the number of waves passing each second (= frequency), and multiply by the length of each (= wavelength) to find the speed. speed = distance/time = l/T= l / (1/f) = f λ. Work through three examples: A simple example, perhaps for sound in air, with values in Hz and m.

Amplitude is the fluctuation or displacement of a wave from its mean value. With sound waves, it is the extent to which air particles are displaced, and this amplitude of sound or sound amplitude is experienced as the loudness of sound

But it seems that in some circumstances, sound can jump between objects in a vacuum after all. Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
