Developing Your Arguments Claims form the basis of an argument. They’re detailed statements that you must prove. Consider how you’ll support your claims with evidence using credible sources such as My NASA Data and NASA Climate Time Machine. You can use other reliable sources as well.

Write down two or three claims for your argument and include evidence to support each of your claims. Cite the sources for your evidence using a URL address or book or journal title.

indium, and thallium have three electrons i think

1 is the answer to this problem

(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

i believe the answer is 5,000
