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.
d= 8/10 so yah that was a guess
Answer:
C(i) the elements are lead (Pb), nitrogen (N) oxygen (O). Lead is found as the Pb 2+ ion and nitrogen and oxygen form the nitrate ion NO 3 –. Its chemical formula is Pb (NO 3) 2.
C(ii) is +2 because the oxidation state of lead is +2. More Lead (II) trioxonitrate(v) is composed of lead ion and the nitrate ion.
I hope this helped
Answer:
No oxygen
Explanation:
when something is covered in a blanket it prevents the fire from being able to have any oxygen
