What climate factor is responsible for the snow on my Kilimanjaro
Nimfa-mama [501]
The climate factor that is responsible for the amount of snow on Mt. Kilimanjaro is high elevation. In the concept of precipitation, as an air mass rises and cools, its capacity to hold water vapor lessens. This vapor condenses into water droplets, forming clouds. Terrain with high elevation attracts such formations, bringing with them cloudiness, rainfall, and snowfall.

A piece of silicon sample has a resistivity of 0.1 ω.Cm. Its thickness is 100µm. The electron mobility is 1350cm 2 v -1sec-1. Wh
lawyer [7]

The answer is Rh = 135 cm^3 and B = 0.05185 wh/m^2


Explanation:

Resitivity of silicon = 0.1

thickness = 100um

so, I = ma

Required to find out concentration of electron , we know that

Rh = up

By putting in the values,

Rh = 1350 x 0.1

Rh = 135 cm^3


Now consider,

Rh = 1 / Rh.q

= 1 / Rh . q

= 1 / 135 x1.609 x10^-19

= 4.6037 x 10^16 / cm^3

Vh = BIRh / w

B = Vh w/ IRh

B = -70 x10^-6 x 100 x10^-6 / 1x 10^-3 x 135 x 10^-6

B = 0.05185 wh / m^2
