Answer:
UV radiation, extreme temperatures and low density of gas.
Explanation:
- The thermometer is a layer of the earth that is directly found over the mesosphere and is has an atmosphere of the UV rays and the photoionization of the molecules that leads to the creation of the ionosphere. Here the temperatures are severed and vary with the solar activity and despite the high temperature it has a low density of the gas.
- The presence of the Thermospheric storms that occur in the high altitudes is a giant storm and is due to the impulsive form of disturbance, with the respect to the magnetosphere disturbance.
Given:
62% of the residents visit Comet Mall.
73% of the residents visit Star Mall.
48% of the residents visit both malls.
To find:
The probability that a resident chosen at random shops at either Comet Mall or at Star Mall.
Solution:
Let A be the event that the residents visit Comet Mall and B be the event that residents visit Star Mall. Then, we have



We need to find the probability that a resident chosen at random shops at either Comet Mall or at Star Mall. It means, we have to find the value of
.
We know that,

On substituting the given values, we get


Therefore, the probability that a resident chosen at random shops at either Comet Mall or at Star Mall is 87%.
Ejemplos de fuerzas
En la naturaleza, las fuerzas fundamentales son la gravedad, la fuerza nuclear débil, la fuerza nuclear fuerte, la fuerza electromagnética y la fuerza residual. La fuerza fuerte es lo que mantiene unidos protones y neutrones en el núcleo atómico.
Explanation:
A warm front is indicated on the line by red semi-circles pointing away from the warmer air and pointing in the direction towards which the warm air is moving. Along sections of the polar front, cold and warm air masses may move differentially with for one another.
