A "FORCE" is required to cause acceleration or cause an object to move.
Answer:
group # = # valence electrons
group 2= 2 valence electrons
Explanation:
Mg is in group #2 and subsequently has 2 valence electrons (electrons on the outermost shell)
Answer:
<h2>12.5 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2.5 × 5
We have the final answer as
<h3>12.5 N</h3>
