Answer:
landslide
Explanation:
Landslide is one of the natural disasters in which the downward movement of the soil and rocks takes place. This results in the massive loss of life and property if happens in the populated area. Heavy rainfall is one of the reasons that trigger landslides. The soil absorbs a lot of moisture and gains a huge weight. This leads to the flow of soil in the downward direction. The earthquake also leads to landslides. The given description describes the landslide.
Finding the new mean is simple: If ![E[X]=10](https://tex.z-dn.net/?f=E%5BX%5D%3D10)
, then ![E[2X]=2E[X]=20](https://tex.z-dn.net/?f=E%5B2X%5D%3D2E%5BX%5D%3D20)
.
Meanwhile, the standard deviation is the square root of the variance, which is given by
![V[X]=E[X^2]-E[X]^2\implies V[2X]=E[(2X)^2]-E[2X]^2=4E[X^2]-(2E[X])^2](https://tex.z-dn.net/?f=V%5BX%5D%3DE%5BX%5E2%5D-E%5BX%5D%5E2%5Cimplies%20V%5B2X%5D%3DE%5B%282X%29%5E2%5D-E%5B2X%5D%5E2%3D4E%5BX%5E2%5D-%282E%5BX%5D%29%5E2)
![\implies V[2X]=4\underbrace{\left(E[X^2]-E[X]^2\right)}_{V[X]}=12](https://tex.z-dn.net/?f=%5Cimplies%20V%5B2X%5D%3D4%5Cunderbrace%7B%5Cleft%28E%5BX%5E2%5D-E%5BX%5D%5E2%5Cright%29%7D_%7BV%5BX%5D%7D%3D12)
and so the new standard deviation would be ![\sqrt{V[2X]}=\sqrt{12}=2\sqrt3](https://tex.z-dn.net/?f=%5Csqrt%7BV%5B2X%5D%7D%3D%5Csqrt%7B12%7D%3D2%5Csqrt3)
.
A greenhouse works in a convection way, since sunlight is energy that flows through the greenhouse windows, it then hits a solid surface and turns into heat. Think of it like an convectional oven, the light of the 1100 watt light bulbs used in an electronic oven hits and bounces off the oven walls(which are a solid surface) and turns into heat in order to cook your food.
