The amplitude of a wave is the distance between a point on one wave and the identical point on the next wave. The period and wavelength of a wave are inversely proportional.
At almost the opposite point on the Earth's surface, the "P" waves reappear. The shadow zone exists because the waves are refracted as they pass through the boundary between the mantle and the core and are diverted from their original paths.

Explanation:
The average speed :
1. 10.44 m/s
2. 10.42 m/s
3. 9.26 m/s
The distance 100 m have the greatest average speed

Given
Distance and time of runner
Required
Average speed
Solution
<em>
Average speed : total distance : total time
</em>
1. d = 100 m, t = 9.58 s
Average speed : 100 : 9.58 = 10.44 m/s
2. d=200 m, t=19.19 s
Average speed : 200 : 19.19 = 10.42 m/s
3. d=400 m, t = 43.18 s
Average speed : 400 : 43.18 = 9.26 m/s
The distance 100 m have the greatest average speed
Explanation:
Mg+O>MgO
Here the mg loses it electron and is oxidised and oxygen gains and is reduced.
Mg(2+)and O(2-)
Mg is a reducing agent it makes oxygen to be reduced while itself being oxidised and vice versa.
