Explain how the absorption of sound waves differs from the transmission of sound waves

1 answer:

4 0

When a sound wave meets an obstacle, some of the sound is reflected back from the front surface and some of the sound passes into the obstacle material, where it is absorbed or transmitted through the material.

Reflection and absorption are dependent on the wavelength of the sound. The percentage of the sound transmitted through an obstacle depends on how much sound is reflected and how much is absorbed. We are assuming that the obstacle is relatively large, such that no sound passes around the edges.

What is it's speed at this time? A rocket blasts off and moves straight upward from the launch pad with constant acceleration. A

zhenek [66]

Answer: 31.85 m/s

Explanation:

Since we are talking about constant acceleration, we can use the following equation to find the speed $s$ of the rocket:

$s=\frac{d}{t}$

Where:

$d=86 m$ is the distance the rocket has traveled

$t=2.7 s$ is the time in which the rocket has traveled the distance $d$

Solving the equation with the given data:

$s=\frac{86 m}{2.7 s}$

$s=31.85 m/s$ This is the rocket's speed

4. What happens to energy during the formation of a solution?

Svetlanka [38]

D It is released or absorbed.

Explanation:

To form a solution, energy is absorbed or released in the process.

A solution is a substance made up of solute dissolved in a solvent. The solute is the dissolved substance where as the solvent is the dissolving medium.

To form a solution, solutes are dissolved.
In this dissolution reaction, energy is used to break bonds within the solute to bring them in contact with the solvent.

The combination of the solute with the solvent is a bond formation process.
Bond formation is an exothermic process in which energy is released.
Bond breaking process is endothermic in which energy is absorbed.
To form solutions, bonds are formed and broken.
