Catalytic ozone destruction occurs in the stratosphere where the reactions involving bromine, chlorine, hydrogen, nitrogen and oxygen gases form compounds that destroy the ozone layer. The reactions uses a catalyst (speeds up the reaction) in a two step reaction. considering chlorine the reactions appears as follows;
step 1
Cl + O3 = ClO + O2
step 2
ClO + O = Cl + O2
Where by chlorine is released to destroy the ozone layer, this takes place many times even with the other elements (hydrogen, bromine, nitrogen) and the end result is a completely destroyed Ozone layer
Answer:
The height of the image is, h' = 6.0 cm
The image is erect.
Explanation:
Given data,
The object distance, u = -5 cm
The focal length of convex lens, f = 10 cm
The object height, h = 3 cm
The lens formula,
v = -10 cm
The magnification factor of lens
m = 2
h' = 6 cm
The height of the image is, h' = 6 cm
The image is erect.
Assuming the objects roll down the inclined plane, yes.
If the object never touches the plane, then no.
Answer:12.206 cm,
Explanation:
Given
Insect walks 15 cm to the right
so its position vector is
Now it moves 10 cm up so its new position vector
Now it moves 8 cm left so its final position vector is
so its displacement is given by
For direction, let \theta is the angle made by its position vector with x axis
