It’s wave motion. Because when wave passes throug an object, some of the other material can go though on other object(s).
Answer: Volume of the balloon at this altitude is 46.9 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 737 mm Hg
= final pressure of gas = 385 mm Hg
= initial volume of gas = 28.6 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Thus the volume of the balloon at this altitude is 46.9 L
A) Mass Number
B) Protons and Electrons
C) (I think group but I'm not 100% sure on this...)
D) 12 (To work out the number of neutrons you do MASS number - ATOMIC number aka the number of protons so in this case you'd do 23-11=12)
Hope this helps
