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.
Imagine A is a Heterogeneous mixture because it a mixture composition that does not stay the same throughout the mixture.
Imagine B is the Homogeneous mixture because it has no changes or irregularities
Answer:
<h2>18 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 2 × 9
We have the final answer as
<h3>18 kg.m/s</h3>
Hope this helps you
