Igneous rock is formed by the cooling and solidification of molten earth materials. igneous rock forms when magma or lava cools. if underground pockets of magma and solidify, igneous rock is formed, such as granite.
a) cools quickly, extrusive
b) cools quickly, intrusive
c) cools slowly, extrusive
d) cools slowly, intrusive

hope this !

explanation:

what are the two models

explanation:

it's c (engineer's do their work with mechanical stuff not on any living being)

(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
