Answer:
<h2>
"The sound wave traveled more quickly through the water than the balloon."</h2>
Explanation:
A sound is produced by <em>vibration. </em>These vibrations are called<u><em> "sound waves."</em></u> In order for sound waves to travel, it needs a particular medium. This medium can either be <em>solid, liquid or gas.</em>
Remember that sound waves travel faster in a <u>"solid medium,"</u> because this matter is denser than the other two. Sound waves travel faster in liquid than in gas, because water is densely packed with particles than gas (such as air).
In the situation above, the answer is "The sound wave traveled more quickly through the water than the balloon." As I've mentioned earlier, sound waves travel faster in liquid than in gas. Thus, the sound waves traveled faster through the glass of water (liquid) than the helium (gas) balloon.
Answer:
4.07 × 10⁹ mL
Explanation:
Step 1: Given data
Length of the pool (L): 60.0 m
Width of the pool (W): 35.0 m
Depth of water in the pool (D): 6.35 ft
Step 2: Convert "D" to m
We will use the relationship 1 m = 3.28 ft
Step 3: Calculate the volume of water (V)
We will use the following expression.
Step 4: Convert "V" to mL
We will use the relationship 1 m³ = 10⁶ mL.
