Answer 1

1. Sky is blue in color because tiny molecules of air scatter blue light from the sun more than they scatter red light. Secondly blue is scattered more than other colors because it travels as shorter smaller waves.So we see a blue sky most of the time.
2. Answer: The moon does not produce its own light. We can only see the moon when light coming from the sun is reflected off of its surface. This means that whenever the moon reflects the sun's rays we can see it–even in the day time.
3. Answer. Multiply Earths surface area of 197 million square miles by four billion to give you the number of square inches. Take Earths atmospheric pressure being an average 14.7 lbs(6.6kg) per square inch, this means that the sky weighs roughly 5.2 million billion metric tons.
4. Answer. Earth weighs about 13,170,000,000,000,000,000,000,000 pounds (or 5,974,000,000,000,000,000,000,000 kilograms).
5. Answer: A plane's engines are designed to move it forward at high speed. That makes airflow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky.
6. water is wet because it is a liquid substance and it has less forces of attraction between its atoms than the solid substance.
7. a rainbow is made by sunlight and atmospheric conditions.
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.

Answer 2

heya mate answer to your question is attached one by one

Why is sky blue

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Why does the moon appear in the daytime?

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."

How much does the sky weigh?

Sky is nothing it is just the mixture of air and water however sky as a whole holds about 38,593,169,564 pounds of water in the air.

therefore its total weight calculated by sophisticated equipment is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds!

How much does the Earth weigh?

Earths weight calculated by sophisticated instruments is found to be 5.972 × 10^24 kg

How do airplanes stay in the air?

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. I had attached q photo for same which will clear u the most

Why is water wet?

Water is wet because when you have water on your clothes or skin it evaporates into the surrounding air. Evaporation produces cooling because it's like energy.

What makes a rainbow?

its all the result of refraction 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.

Why don't birds get electrocuted when they land on an electric

Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.
