why did it matter that bacteria from the fecal transplant can fill up the space in the gut, limiting the food and space invading harmful bacteria. write two paragraphs that supports your claim. PLEASE ANSWER THE QUESTION NOW! THANK YOU ‼️‼️‼️‼️‼️‼️

the answer is 0.42 is that is an option. this question provides no info

answersilicon (si); oxygen (o);

(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
