Answer: It is the result of a mixture of radiation from many independent sources, such as stars and galaxies.
Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it. In fact, it is the leftover radiation from the Big Bang that occurred 400,000 years before the events related to this cosmic radiation.
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.

Answer:
A one-step conversion is not sufficient to convert a temperature in the Celcius scale to the Fahrenheit scale.
Explanation:
Hello!
To convert a temperature in the Celcius scale to the Kelvin scale we required just one-step conversion, because we consider that the first scale derives from the second scale.
Celcius scale begins at 0 degrees (0°C), wich coincides with the melting point of the ice, and ends at 100 degrees (100 °C) with the point of water boiling point.
Fahrenheit scale determines that the freezing point of water is located at 32 degrees (32°F) and its boiling point at 212 degrees (212°F). This situation causes a 180 degree interval between the two points.
For this reason, to calculate how many Fahrenheit degrees has a certain temperature expressed in Celcius degrees, we have to multiply the X degrees Celcius (°C) by 1.8, and then add 32 to the previously obtained result.
°F= (X°C x 1.8) + 32
