Why is the sky blue?

How much does the sky weigh?
How do airplanes stay in the air?
Why is water wet?
Why don't birds get electrocuted when they land on an electric wire?
Answer:
the sky is blue because of reflection of blue light of sea and ocean.
the moon appear in the daytime because light of sun is brighter than of moon
airplanes stay in the air by maintaining balance in air and gravity.
birds did not get electrocuted when they land on an electric wire because there body is non conductor.

If one wall of a room consists of a large flat mirror, how much larger will the
room appear to be? Explain your answer.
Answer:
The room will appear to be twice as big because the object distance is equal to the image distance. The mirror takes into account the distance between the mirror and how big the room is.

Answer:
1.308104*10^-8 N (1.31*10^-8 N when rounded)
Explanation:
The mathematical formula for gravitational force is F = G Mm /r^2 where G is the gravitational constant which is measured 6.674 *10^ − 11 N (m/kg) ^2.
Since both objects, M and m, have masses of 70kg and the distance r is 5 meters, then we can plug these values into the formula:
F=GMm/r^2
F=(6.674*10^-11)(70)(70)/(5^2)
F=(6.674*10^-11)(4900)/25
F=(3.27026*10^-7)/25
F=1.308104*10^-8
So the gravitational force of attraction between the two objects is 1.308104*10^-8 N.

What is the evidence that an asteroid collision has happened before?
Answer:
The first clue that an asteroid had struck earth at around the same time as the mass extinction was the amount of iridium around the K-T boundary. Another clue was that they found that most animals that lived in the cretaceous died when the asteroid crashed and they found bones of animals from the cretaceous.

How do we know when an object is in static or dynamic equilibrium?
Answer:
First Condition of Equilibrium
Explanation:
This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.Why does it take a long time for the earth to rotate?
24hrs or i full year as in 365 days
Answer:
earth takes a long time to rotate due to the tidal effects the moon has on earth's rotation
Explanation:
I hope this helps!
