Earths climate history
Short writing

Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Explanation:

In short words , Earths climate went from cold this is due because ; of the global Ice Age. After the rock showers hit it released large amounts of carbon it heated up the atmosphere causing the word to have bacteria and grow livable life-forms again. 2021 we are producing too much carbon and this is leading factor of climate change not only is the earth already warm enough but its rapidly heating up. An example of this is ETC - "I live in CA and since the start of Autumn we haven't had and glimpse or foreshadowing of cold weather its been 80* everyday and hasn't dropped one bit not even in the morning."

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
