<u>Answer</u>:
The mass of a star can be determined by studying binary star systems.
<u>Explanation</u>:
In this system it consists of two stars, revolving round the same bary-centre. The systems having two or may say more than two are called as the multiple star system. This zone is also a habitable zone, here the water exists in the liquid form. We could have sometime seen the two stars together. They are also very capable of strengthening the terrestrial planets inside the stable orbital ranges. They have generally two orbits like P-type as well as circumbinary.
The correct answer is:
Gravitational pull is greater on earth . As weight = mass × g so we have more weights on earth than on moon.
Explanation:
This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight. As the moon has secondary mass than the earth, it has a lighter gravitational influence and hence, we weigh less on the moon.
Answer: I think three red and one white.
Hope this helps.
Explanation:
Answer:
3215 F would be the platinum melting point.
it boiling point is 6917 F.
Explanation:
There is not much to explain other then heat melts metals when high enough, I know this because I own a forge and platinum is one thing I use for melting.
