A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.
“Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each ...
The thrust is generated by the jet engines, and this helps the plane to propel forwards, whereas the lift force acts on the plane wings and allows it to move upwards, and also to maintain its altitude. For a plane to stay in the air, the lift force needs to overcome the force of gravity.
