Suppose your class invites a person to give a speech. When you test out the sound system in the gym you find there are so many echoes the speaker cannot be understood. What needs to be done to fix this problem?

Answers

Answer:

You either need to lower the volume so the sounds intensity is lessened. Or you can pad the walls to absorb the sound rather than defect.

Explanation:

Sound intensity allows it to be heard further, but in an enclosed room it will start returning. Sound will deflect off of hard objects do to its interactions with solids. A softer and foamy material can dampen it.

According to "Take a Closer Look", what type of lens is used to correct nearsightedness?

Answers

Answer: A.) concave lens

Explanation: i hope this helps shawtay :)

In general, a concave lens (also known as a diverging lens) is used to correct nearsightedness, as stated in "Take a Closer Look." Option C is correct.

What is the lens?

A lens is an optical component that is used to refract (bend) and focus light. It is typically made of a transparent material, such as glass or plastic, and has a specific shape that allows it to alter the path of light as it passes through.

Here,
In general, a concave lens (also known as a diverging lens) is used to correct nearsightedness, as stated in "Take a Closer Look."

A concave lens is thinnest at the center and thicker at the edges, which causes light rays passing through the lens to diverge or spread out. By placing a concave lens in front of a nearsighted eye, the lens causes incoming light rays to diverge more before they reach the eye's lens, which then focuses them properly on the retina, resulting in clearer vision.

What is the intensity of sound produced by an elephant's call if it has a power of 0.45 W and you are standing 32.5 m away from the lumbering beast

Answers

Answer:

I = 1.36 x 10⁻⁴ W/m²

Explanation:

The intensity of the sound produced by the Elephant can be calculated by using the following formula:

[tex]I = \frac{P}{A} \\\\[/tex]

where,

I = Intensity of sound = ?

P = power of sound = 0.45 W

A = area = πr² = π(32.5 m)² = 3318.3 m²

Therefore,

[tex]I = \frac{0.45\ W}{3318.3\ m^2} \\\\[/tex]

I = 1.36 x 10⁻⁴ W/m²
