We can study how galaxies evolve because the farther away we look, the further back in time we see.
Answer: Option D
<u>Explanation:</u>
As the galaxies are located far away from us and also as per the broad band theory, these galaxies are spreading as the time goes. So as time passes, the galaxies are moving further light years away.
So depending upon the time taken for the light waves to reach Earth from these galaxies will state the time they have evolved. So the farther or more lately the light reaches the earth surface, the further time back we can see its evolution. Thus option d is correct choice.
Answer: Descartes was more of speed which defers from modern day velocity.
Explanation:
Descartes law if conservation referred or defined “motion” rather than “momentum” as what is obtainable in today's world as ”speed” the rate at which something moves rather than “velocity” which is a product of speed and direction. So in conclusion Descartes was more of speed which defers from modern day velocity.

Answer: The new gas pressure is 150 kPa.
Explanation :
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
= initial pressure of gas = (100+200) kPa = 300 kPa
= final pressure of gas = ?
= initial volume of gas = v
= final volume of gas = 2v
Therefore, the new gas pressure is 150 kPa.
