The sum of the heights of all 3 isotopes would be 62+2+8 = 74
<span>The fractional abundance of 20-Ne 2ould be 62/74 = 0.861. </span>
<span>You can just divide the height of each of the other isotopes by the total height to get their relative abundances.
I hope my answer has come to your help. God bless and have a nice day ahead!

In this problem, you’re given a mass (m) and a force (F) applied to an object and you’re asked to calculate the acceleration (a). If we plug this into the provided equation:
F = ma
(7.3 N) = (3.2 kg)a
a = 2.3 m/s/s
The acceleration of the object is 2.3 m/s/s.
Hope this helps!
I'm guessing you mean Oxygen, right?
Percent composition by mass is found by finding the total molas mass of the compound and the mass of oxygen and dividing the mass of oxygen by total mass.
1. The molar mass of Ca(OH)2 is <span>74.0958 amu. There are 2 oxygens, so 16 x 2 = 32 amu.
32 amu/ </span>74.0958 amu = <span>43 % Oxygen
2. </span><span>C6H2O = 18% Oxygen
3. </span><span>K2SO3 = 30% Oxygen
4. </span><span>Li2SO4 = 58% Oxygen
5. This is the only one not having Oxygen but it's 82% Cobalt and 18 % Calcium

If you consider the motion of the slinky as just one object, you can look at it's center of mass. From the whole slinky point of view, there is only one force on the slinky - the gravitational force. This means that it falls and accelerates downward with an acceleration of -9.8 m/s2 just like all free-falling objects. Plze mark brainiest
