Answer: a. oxidation
Explanation:
The weathering is a process through which the large rocks are broken into small rocks or pieces. The weathering can be caused by the physical and chemical agents.
The chemical weathering is a process in which the rock is disintegrated or broken into sub-components by the action of the chemical agents present in the surrounding of rock for example, air, water, acid, and alkali.
The air will cause the oxidation of the rocks. This will cause weathering of rocks as the oxygen will react with the minerals present in rocks making their bonds weak and causes disintegration of rocks.
<span>The destructive force of waves is not felt in open ocean, for example boats far away from the coastline can ofter survive even catastrophic tsunamis. The force is felt and damage is done once the waves reach land, or very shallow water.</span>

Answer:
0.546 ohm / μm
Explanation:
Given that :
N = 1.015 * 10^17
Electron mobility, u = 3900
Hole mobility, h = 1900
Ng = 4.42 x10^22
q = 1.6*10^-19
Resistivity = 1/qNu
Resistivsity (R) = 1/(1.6*10^-19 * 1.015 * 10^17 * 3900)
= 0.01578880889 ohm /cm
Resistivity of germanium :
R = 1 / 2q * sqrt(Ng) * sqrt(u*h)
R = 1 / 2 * 1.6*10^-19 * sqrt(4.42 x10^22) * sqrt(3900*1900)
R = 1 /0.0001831
R = 5461.4964 ohm /cm
5461.4964 / 10000
0.546 ohm / μm
