Answer:
[tex]10^{3}[/tex]
Explanation:
(i) The mass of an electron:
[tex]9.11*10^{-31}kg[/tex]
(j) The mass of a proton:
[tex]1.67*10^{-27} kg[/tex]
[tex]9.11*10^{-31}kg * x = 1.67*10^{-27} kg[/tex]
[tex]x = 0.18 * 10^{4}[/tex], then [tex]1.8*10^{3}[/tex] or 1800
Here my answer is 10^3 because I expressed order of magnitude.
It's when we approximate to the nearest tenth power.
