You have two to. atom 1 ha 12 proto 12 metrom und 12 election. atom #2 has 12 proton and 13 metrom und 12 electron. which of the following statements isſare) true? o a. atom 1 h ver has greater than atom #2 o atoms are different steps of the weet o atoms 1 and 2 are not the same type of eleme o d. all positive electrical charge and atomh i ve electrical charge

yes they ca   is ur ansswerrr

(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
