The radius of the hydrogen atom is 0.529x10/-10 and the radius of the nucleus is 1.2x10/-15m. Compare the radius of each by writ
raketka [301]

we know that

The radius of the hydrogen atom is  0.529*10^{-10}m

The radius of the nucleus is  1.2*10^{-15}m

the ratio is equal to

\frac{0.529*10^{-10}}{ 1.2*10^{-15}} = 44,083.33

that means the radius of the hydrogen atom is 44,083.33 times the radius of the nucleus

therefore

<u>the answer is</u>

the ratio is equal to 44,083.33

For which equations are in the solution for x the same number? 15 – х = -3<br> 3
Norma-Jean [14]

Answer:

Step-by-step explanation:

First equation:

          15 - x = - 3

           -x = - 3 - 15

          -x  =  -18  (now negative signs on b.s cut eachother)

            [x  =  18]

Second equation :

         15 - x = 3

          -x = 3 - 15

          - x = -12 ( now negative sign on b.s cut eachother)

            [x = 12]

so x = 18 and x = 12 are not same
