Which element has the largest average
1 answer:
<h2>Answer:Xenon</h2>
Explanation:
The average atomic mass of an element is defined as the sum of the masses of its isotopes,each multiplied by their natural abundances.
Option A:
Argon has a average atomic mass of
Option B:
Xenon has a average atomic mass of
Option C:
Krypton has a average atomic mass of
Option D:
Neon has a average atomic mass of
So,Xenon has the highest average atomic mass.

Answer:
1.25 s
Explanation:
We are given that
Initial velocity of boy=u=0
Time=0.883 s
Let x be the total distance covered by boy in entire trip.
s=
We know that
Where
Substitute the values
m
Again using the above formula
Hence, 1.25 s passes during his entire tripe from the top down to the water.
The correct answer is "absolute temperature".
In fact, Charle's law states that, for a fixed amount of gas kept at constant pressure, the ratio between the volume of the gas V and its absolute temperature T is constant:
And this equation can be also read as: when V changes, T changes by the same proportion, so this means that the volume V is directly proportional to the absolute temperature T of the gas.
