What how many degrees variation is there between the highest temperatures and lowest temperatures on the moon? about 550ºC about
1 answer:
Answer:
about 310ºC
Explanation:
The Moon is the natural satellite of the Earth.
The Moon orbits around the Earth in approximately 27 days, and its average distance from the Earth is about 380,000 km.
Moreover, the mass of the Moon is .
The Moon has no water on its surface and no atmosphere: due to the lack of atmosphere, heat coming from Solar radiation is not retained near the surface. Moreover, the Moon orbits around the Earth keeping one face always towards it, so every location on the Moon has 13 consecutive days of daylight followed by 13 days of darkness.
As a result, there is a large thermic excursion between the maximum and minimum temperature on the Moon. In particular, we have:
- Minimum temperature: -173 degrees Celsius
- Maximum temperature: +127 degrees Celsius
So this difference is about
So, about 310ºC.

The question is incomplete, here is the complete question:
A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.
Answer: The wavelength of the radio waves is 4.54 m
<u>Explanation:</u>
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
c = speed of light =
= frequency of light =
Putting the values in above equation, we get:
Hence, the wavelength of the radio waves is 4.54 m
