Answer:
Explanation:
In this case, we need to find the value of expression :
On solving, we get the value of given expression as :
x = 9.7827
In scientific notation, we get the value of x as :
a = 9.78
k = 0
Hence, this is the required solution.
P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km. S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids. ... The core has a radius of 3470 km.
Answer:
D) diffraction
Explanation:
Corona is an optical phenomenon produced by the diffraction of sunlight or moonlight, as light moves through water droplets in the atmosphere.
This phenomenon produces one or more diffuse concentric rings of light around the Sun or Moon, usually seen as colored circles.
Therefore, the explanation for these phenomena of colored concentric circles, sometimes seen with the Sun or the Moon involves diffraction.
