How astrophysics Applied on planets
Answers
Astrophysics is a branch of space science that applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. It has two sibling sciences, astronomy and cosmology, and the lines between them blur.
Hubble Snaps 'Monkey Head' Nebula
The Hubble mosaic unveils a collection of carved knots of gas and dust in a small portion of the Monkey Head Nebula (also known as NGC 2174 and Sharpless Sh2-252). The nebula is a star-forming region that hosts dusky dust clouds silhouetted against glowing gas.

In the most rigid sense:
- Astronomy measures positions, luminosities, motions and other characteristics
- Astrophysics creates physical theories of small to medium-size structures in the universe
- Cosmology does this for the largest structures, and the universe as a whole.
In practice, the three professions form a tight-knit family. Ask for the position of a nebula or what kind of light it emits, and the astronomer might answer first. Ask what the nebula is made of and how it formed and the astrophysicist will pipe up. Ask how the data fit with the formation of the universe, and the cosmologist would probably jump in. But watch out — for any of these questions, two or three may start talking at once!
Goals of astrophysics
Astrophysicists seek to understand the universe and our place in it. At NASA, the goals of astrophysics are "to discover how the universe works, explore how it began and evolved, and search for life on planets around other stars," according NASA's website.
Hope it helps...u..
Sry not sure about the answer...
iss achha toh dusre method se hi kar lena,
ncert mai dusra method bhi toh diya hua hai, by reversing the AP wala aur ek formula bhi toh hota hai,
an = l - ( n-1)d
esa kuch, usse kar Lena
