Answer:
Explanation:
Ne has its outside shell full of electrons; therefore, its reaction with other elements is minimal if at all. Na, the next element, has 1 more proton and 1 more electron. More importantly that added electron is in the outside shell. It can fill that shell by ADDing 7 more electrons or LOSing the one electron. Obviously, it loses the one electron and it does so with gusto which makes Na a very reaction element while Ne is not reactive at all. Now follow oobleck's instructions, add what you read to what I've written,then summarize all of it in your own words.

The correct answer for this question is A. Light
Answer:
The force the skater exerts is 50 N
Direction: towards wall
Explanation:
The impulse is equal to:
The average force is:
Where
vf = final speed = -1 m/s
vi = initial speed = 0
m = mass = 40 kg
Δt = time interval = 0.8 s
Replacing:
(force applied by the wall)
The force the skater exerts is
Fsk = -Fave = -(-50) = 50 N
Direction: towards wall
