Which of the following statements is an accurate description of sound transmission through various mediums ? a. in elastic materials conduct sound better than elastic solids b. gases conduct sound better than liquids c. sound insulators prevent sound being transmitted better than elastic solids d. elastic solids prevent sound from being transmitted better than liquids

Sound insulators prevent sound being transmitted better than elastic solids

Explanation:

We know that sound waves are longitudinal in nature. The particles of waves travel in a direction parallel to the direction of motion of the wave. It travels in the form of compression and rarefaction.

The speed of sound is maximum in solids. Sound insulators are substances that prevent the sound to travel. The materials that are less elastic can absorbs sound as compared to inelastic materials.

So, the correct option is (c) "Sound insulators prevent sound being transmitted better than elastic solids".

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
