Explanation:
In periodic motion, amplitude is half the distance between the minimum and the maximum.
A = (max - min) / 2
Covalent bonds are formed through an electrostatic attraction between two oppositely charged ions. Hope this Helps :)
Explanation :
According to astronomers, the whole universe is started with a giant explosion called as Big Bang. Big Bang theory shows that the universe is extended from high density state.
There are some evidence for big bang as :
(1) There are some red shifts of different galaxies which means that the universe is expanding.
(2) Due to the expanding of universe, some of the new elements are created like hydrogen, deuterium etc.
(3) Microwaves are detected by orbiting detectors.
All this parameters shows that big bang theory was correct.
Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth is the answer
im not 100% sure tho
hope it helps:))
