Explanation:

• Four forces keep an airplane in the sky. They are lift, weight, thrust and drag. ... The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.
• Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.
• 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
