Answer:

A sound is an energy source, much like electricity, heat or light. That makes a loud ringing noise when you hit a bell. Now put your finger on the bell after you’ve hit it, rather than just listening to the bell. You can feel it shaking and this motion or moving, i.e., the body’s to and fro motion is termed as vibration.

Sound is a vibration that passes through the medium in the form of longitudinal waves. It implies that sound waves are waves wherein the particles of the medium vibrate parallel to the direction of wave propagation. Sound forms are known as mechanical waves because they require a propagating medium. The medium may be

Solids

Liquids

Gases

Properties of sound

Frequency or pitch

Frequency is the number of cycles of periodic compression and rarefaction which occur every second as the wave propagates via the medium.

The human ear’s interpretation of the sound level within the range of human hearing is called the pitch.

The higher the sound frequency, the higher the pitch is and a lower frequency means a lower pitch.

Speed

The speed at which the sound waves travel via the medium is called sound speed. The speed of sound for different mediums is different. Sound moves in solids faster, as the atoms in a solid are packed tightly.

Amplitude or Loudness

The loudness determines the amplitude of the sound waves.

The sound amplitude is a measure of the magnitude of the overall sound disturbance.

The amplitude is a measure of the vibrational energy.

More energetic vibration is responsible for a greater amplitude.

Timbre

Timbre is the property used to distinguish between sounds of the same frequency.

Timbre based on what substance the sound is created from.

Reflection of sound

As sound waves encounter a solid or light surface, it bounces back into the same medium. It is termed as sound reflection. Sound waves obey the laws of reflection, like light waves.

Compute the solution to x + 2x + 2x = 0 for Xo = 0 mm, vo = 1 mm/s and write down the closed-form expression for the response.

Nutka1998 [239]

Answer:

β = $\frac{c}{\sqrt{km} }$ = 0.7071 ≈ 1 ( damping condition )

closed-form expression for the response is attached below

Explanation:

Given : x + 2x + 2x = 0 for Xo = 0 mm and Vo = 1 mm/s

computing a solution :

M = 1,

c = 2,

k = 2,

Wn = $\sqrt{\frac{k}{m} }$ = $\sqrt{2}$

next we determine the damping condition using the damping formula

β = $\frac{c}{\sqrt{km} }$ = 0.7071 ≈ 1

from the condition above it can be said that the damping condition indicates underdamping

attached below is the closed form expression for the response

As part of a chemistry experiment, Austin ends up with a beaker containing a mixture of two liquids, which he knows have boiling

asambeis [7]

Answer:

Distillation, heat

Explanation:

Here in this question, we simply want to look at the best options that could fit in the gaps.

We have a mixture of liquids having boiling points which is far from each other.

Whenever we have a mixture of liquids with boiling points far away from each other, the best technique to use in separating them is to use distillation. That is why we have that as the best fit for the first missing gap.

Now, to get the liquids to separate from each other, we shall be needing the heating mantle for the application of heat. This ensures that the mixture is vaporized. After vaporization, the condensing tube will help to condense the vapor of each of the liquids once we reach the boiling point of either of the two.

Kindly note that the liquid with the lower temperature will evaporate first and will be first obtained. In fact after reaching a little above the boiling point of the lower boiling liquid, we can be sure that what we have left in the mixture pot is the second other liquid with the higher boiling point.

What's the difference between accuracy and percision in measuring and gaging?

lidiya [134]

Answer:

The term Accuracy means that how close our result to the original result.

Suppose we do any experiment in laboratory and we calculate mass = 7 kg but answer is mass = 15 kg then our answer is not accurate.

And the term Precision means how likely we get result like this.

Suppose we do any experiment in laboratory and we calculate mass five times and each time we get mass = 7 kg then our answer is precised but not accurate.
