write a hypothesis that deals with plant growth and fertilizer. identify the independent, dependent, and 5 control variables.

my hypothesis is that if i use nutritious soil with a plant , the plant will grow more healthy and do better, then if i used clay soil.

Dependent=plant  .

Independent=Soil

control variables=

water amount=how much you give it water

sunlight=how long it stays out in the sun

tempature= how hot ,or cold the enviorment is

humidity= if plant needs humidity to do better, example orchids

location=surrounded by other plants, coverd by a shadow

Explanation:

(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
