Using graph a in figure 11-2 calculate the average speed of the object in motion from 12 s to 20 s explain your calculation

Average speed = 50m/s

Step by step explanation:

(x1,y1)=(12,200)

(x2,y2)=(20,600)

Speed

=Gradient

=y2-y1/x2-x1

=600-200/20-12

=400/8

=50m/s

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

compost can be added to topsoil as a:

pesticide
