<h3>What is ozone layer?</h3>
The topmost layer of the atmosphere which protect the harmful UV rays from the Sun to reach the Earth surface.
Mario Molina has the great contribution in science field. He tried hard and succeeded in passing an international agreement to eliminate CFCs also called as Chloro Fluoro Carbons and other ozone-depleting chemicals.
These CFCs were used in jet planes which depleted the ozone layer and a hole was observed over Antarctica.

A mechanical wave is a disturbance in matter that transfers energy through the matter.
Answer:
La respuesta es 16,041.66 M en términos de segundos.
Explanation:
Answer:
0.011 m
Explanation:
From the question,
The speed of a moving wave is related as
c = λf.................... Equation 1
Where c = speed of the wave, λ = wave length, f = frequency.
make λ the subject of equation in equation 1 above
λ = c/f................ Equation 2
Given: c = 3.0×10⁸ m/s, f = 2.75×10¹⁰ Hz
Substitute theses values into equation 2
λ = 3.0×10⁸/(2.75×10¹⁰)
λ =
