During the Gupta golden age, Aryabhata was known for discovering that Earth rotated on an axis.
Aryabhata was a professional at mathematics and astronomy. He calculated the value of pi, calculated the volume of a sphere and area of a triangle, characterized the model of the solar system, and many other things. While studying astronomy, Aryabhata came up with an assumption that Earth rotated on an axis while the heavens orbited around it.

2) D. Mars
3) C. other planets and moons in the solar system and beyond
4) A. lifeforms
5) A. coping with the extreme atmospheres
Answer:
5 metre.
Explanation:
Wavelength = Velocity / Frequency
= 23,000/ 4,500
= 5 metre.
Answer:
1.36
Explanation:
= Index of refraction of air = 1
= Index of refraction of plastic = ?
i = angle of incidence in air = 32.0° deg
r = angle of refraction in plastic = 23.0° deg
Using Snell's law
Sini = Sinr
(1) SIn32.0 = Sin23.0
= 1.36
