Answer:
c)The gases have the same average kinetic energy.
Explanation:
As we know that the kinetic energy of gas is given as

here we know that

so we have

now we have

now mean kinetic energy per molecule is given as

so this is independent of the mass of the gas
so average kinetic energy will remain same for both the gas molecules
Follow stop drop and roll if the fire is in the room
Other wise exit immediately and find the nearest fire point. Then when you are out phone the fire services.
I hope this helps :)
1 is amplitude crest is 5 3 is wavelength. Your chart is confusing so that’s all I got
Mass = 1.2 kg = 1200 grams.
Volume = mass/density = 1200 cm3.
Hope this helps!
