How is ozone formed?
2 answers:
Answer:
The Ozone is produced naturally when solar radiation collide with oxygen molecules .
The solar radiation is high energy, as a result of the collision, oxygen molecules are separated in atoms, this process is known as Photolysis.
After the separation process, oxygen atoms are freed and continuously colliding one another, so here they form molecules.
The major part of the Ozone in the atmosphere is formed over the equatorial zone, because there is the most intense solar energy radiation.

Answer:
Δy = 7.1 cm
Explanation:
The center of mass of a body is defined
= 1 /M ∑
i
Where M is the total mass of the body, m mass of each part and ‘y’ height
Let's apply this equation to our case
We locate the reference system on the shoulders
The height of the arms is at its midpoint
y = -75/2 = 37.5 cm
With arms down
= 1/70 (63 y₀ - 3.5 37.5 - 3.5 37.5)
= 1/70 (63 y)₀ - 7 37.5)
With arms up
’= 1/70 (63 y₀ + 3.5 y + 3.5 y)
’= 1/70 (63y₀ + 7 35.5)
let's subtract the two equations
’ -
= 1/70 2 (7 35.5)
Δy = ’ -
= 2 7 35.5 / 70
ΔY = 7.1 cm
