Answer:
a). 675J
b). 337.5J
c). 1012.5J
Explanation:
M = 6.0kg
V = 15.0m/s
a). Translational energy
E = ½ *mv²
E = ½ * 6 * 15²
E = 675J
b). Rotational kinetic energy K.E(rot) = Iw²
But moment of inertia of a cylinder (I) = ½Mr²
I = ½mr²
V = wr, r = v / w
K.E(rot) = ¼ mv²
K.E(rot) = ¼* 6 * 15²
K.E(rot) = 337.5J
Total energy of the system = K.E(rot) + Translational energy = 337.5 + 675
T.E = 1012.5J
D. Giant kangaroo rats enrich the soil for plants with their piles of grass clippings in the California grasslands.
Explanation:
Giant kangaroo rats enriching the soil for plants with their piles of grass clippings in the California grasslands is an example of how biodiversity contributes to the sustainability of natural environment.
- Biodiversity refers to the variety of life forms in an area.
- The more diverse an ecosystem is, the more sustainable it is.
- Decaying plant pilings cut by the Kangaroos when they decay release useful nutrients to the soil.
- This would not be possible if an animal like the Kangaroo rats are not present.
