please answer me these five questions
1 why is the sky blue
2 how much does the sky weigh
3 why is water wet
4 what makes a rainbow
5 what kind of waves are present during an earthquake
Answers
1 The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. ... These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue.
2 This means the sky weighs 14.7 lbs per square inch of earth surface which is roughly 11 billion billion pounds. So, you can say that sky weighs one millionth of the mass of the Earth. Which equals to 570,000,000,000,000 adult Indian elephants!
3 strong tetrahedral hydrogen bonding, which they then related to their teachers for years afterward whenever the subject of water came, they'd say, “Strong tetrahedral hydrogen bonding!” But that's the correct answer. That's what makes water wet.
4 Sunlight appears white. When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.
5 There are four main types of earthquake waves: P-waves and S-waves (which are body waves), and Rayleigh waves and Love waves (which are surface waves). Love waves tend to cause the most damage due to their large amplitude and P-waves the least, but P-waves are the first to arrive
