Answer:
They take the form of heat or energy.
Explanation:
- The electromagnetic waves have a lengths that are in the range of the 700 nanometers are categorized according to other frequencies and the wavelengths as the visible light and has a wavelength of 400 to 700 nanometers.
- The electromagnetic waves with a shorter wavelength include the higher frequencies include the ultraviolet light, the X-rays, and the gamma rays.
În timpul unei eclipse de Lună, Pământul trece între Lună și Soare, determinând Pământul să-și arunce umbra asupra Lunii.
Veți observa că umbra pe care o produce este rotundă. Chiar dacă Pământul ar fi plat, dar în formă de disc, nu ar arunca nici acest gen de umbră. „Singura formă care poate produce o umbră curbată, indiferent din ce direcție este plasată lumina, este o sferă”, explică Thaller.
Answer:
Deforestation, biodiversity loss, climate change, and land degradation.
Answer:
Star A is 3.343 times hotter than star B.
Explanation:
It is known that the luminosity of a star is proportional to its effective temperature to the 4th power. This means that the ratio between the brightness of stars A and B is equal to the ratio between their temperatures to the 4th power:
![125=T^4\\T=\sqrt[4]{125}\\T=3.343](https://tex.z-dn.net/?f=125%3DT%5E4%5C%5CT%3D%5Csqrt%5B4%5D%7B125%7D%5C%5CT%3D3.343)
Star A is 3.343 times hotter than star B.
