Answer:
<h2>10 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>10 m/s²</h3>
Hope this helps you
c- it says I need to write at least 20 words to submit it so- here haha
The atomic number of Cu = 29
Valence electron configuration of Cu = 3d¹⁰4s¹
Cu+ is formed when 1 electron is lost from Cu. Therefore, the atomic number for Cu+ = 28
Similarly, loss of 2 electrons from Cu results in Cu2+ with an atomic number = 27
Cu+ is the larger ion. This is because as electrons are removed from the valence orbitals, the attraction between the outer electrons and the nucleus tends to increase which then results in a decrease in size.
Ans: Cu+ has one more electron
Protons goes in the blank. the word can be used for both.
