Kiran records the height of each plant—those with a colored filter and those without
Kiran explores the growth of a plant in natural light, then repeats the experiment with the same plant type but
different colored filters.
Kiran turns in a written lab report to her science teacher.
Kiran wonders, "Will colored light affect the growth of a plant?”
Kiran writes in her notes that adding a colored filter over a plant affects its growth because the heights of the plants
under the colored filters were less than the height of the plant with no filter.

give me abc and i will get it for u.

(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
