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.

Answer:
4 Ohms
Explanation:
The challenging part in this circuit is the bridged setup (diamond-shaped arrangement made of the 4 Ohm resistors). In general, this would first need to be transformed using the Wye-Delta transform to be solved, but in this case we can make a valid simplification: since the diamond arrangement is completely symmetrical, the voltage at the top and the bottom tip of the "diamond" will be identical and no current flows through the 4 Ohm bridge, hence, this resistor can be removed without changing the resulting resistance. After this, it is easy to see that the equivalent resistance of the modified "diamond" is just 4 Ohms.
The remaining top parallel branch of the circuit will be 8 Ohms, and the bottom parallel branch is nominally 8 Ohms. The resulting resistance therefore is 4 Ohms.
(The answer is not 2 Ohms!)
Answer:
69 revolutions
Explanation:
given,
initial angular velocity = 0
final angular velocity = 6 rev/s
when safety switch turned off
tub smoothly slows to rest in (t)= 13 s
total revolution of tub = ?
angular acceleration =
angular acceleration =
= 0.6 rev/s²
now,
= 30 revolution
now,
when safety switch turn off
angular acceleration =
angular acceleration =
= -0.462 rev/s²
now,
= 39 revolution
total revolution = 30 + 39 = 69 revolutions.
tub will rotate 69 revolutions
Answer:
Speed and direction affect pitch.
Explanation:
PE= mgh
6 J= (3m) (9.81 m/s2) (mass)
mass=( 6)/(3×9.81)
mass= 0.20 Kg
