Q Search Jamison's 3rd Pd. Mon. and Wed. 10:25-12:25) 9. All of the following conditions in Earth can cause metamorphic rocks to form EXCEPT Pressure The presence of hot watery fluids Heat Exposure to air​

the answers would be

the first one and the second one

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

(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
