Most fabrics do a good job at protecting skin from exposure to sunlight, but addition of uv-absorbing compounds to clothing can further reduce the amount of ultraviolet light that passes through the fabric. the following transformation takes place upon absorption of uv light by one such compound

identify which arrow-pushing pattern is utilized in this reaction.

explanation:

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

(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
