Answer:
1. Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part.
2. We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes. When we see the moon during the day it's because the moon is in the right spot in the sky and it's reflecting enough light to be as bright, or brighter, than the sky."
3. 14. 7 lbs per square inch
4. 5.972 × 10^24 kg
5. Four forces keep an airplane in the sky. They are lift, weight, thrust and drag.
Lift pushes the airplane up. The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.
6. 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.
7.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.
8. The copper in electrical wires is a great conductor. Birds are not good conductors. That’s one reason they don’t get shocked when they sit on electrical wires. The energy bypasses the birds and keeps flowing along the wire instead.
