Here is ur answer.....
Explanation:
1)Sunlight scatters in all directions by all the gases and particles present in earth's atmosphere. Blue light is scattered more than the other colors because its wavelength is shorter. And our eyes are sensitive to blue colour, this is why we see a blue sky most of the time.
It may be possible that some animals see the sky violet instead of blue because violet has shortest wavelength in white light(VIBGYOR).
2)The surface of the moon is reflecting the sun's light into our eyes during night. Similarly, 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) The weight of sky is 14.7 lbs per square inch.
4) The earth weigh 6×10²⁴kg
5)Lift is the force that opposes gravity and helps an airplane to fly. Lift is achieved in part by the design of an airplane's wing.

Explanation:
1)sky is blue due to scattering if light.
2)
3)
4)
5)Four forces keeps the airplanes in air . they are lift ,weight,thrust,drag.
6)Due to“Strong tetrahedral hydrogen bonding,”
7)Rainbow is caused by relflaction,refraction and dispersion of light.
8)Current flows in a loop[ which means the circuit is closed]. A bird sitting on a transmission line does not complete the circuit. If the same bird keeps one leg on one line and another leg (or any part of its body) on another line(or the neutral points), then it will get roasted.
9)yes,NASA gave proof also
10)because water in the ocean absorb long wave length colour
11)sun is close to earth and its light is less scatter than stars
