The best answer is b) increased turbidity from erosion.
Nonpoint source pollution generally happens as a result of many systems interacting, and is not directly attributed to one event or pollutant. Generally, natural environmental systems participate in pollution of this kind, regardless of whether or not human activity was a factor. Examples include water runoff, or erosion.
The other pollutants listed have a direct cause and direct effect, the animal waste goes directly from the animals to the ground they live on, the car shop directly sumps the oil on the ground, and the oil tank leaks directly into the earth. Erosion causing turbidity is a less direct form of pollution, and is due to the synthesis of several natural phenomena<span />
It’s either C or D. let me know but I would do C!
Answer:
It stays the same.
Explanation:
Entropy of a system either increases or remains constant in any process, it never decreases.
An air conditioner uses a
compressor to raise the temperature and pressure of refrigerant.
<span>A </span>refrigerant<span> is a substance or mixture, usually a </span>fluid<span>, used in a </span>heat pump and refrigeration
cycle<span>. In almost all cycles, it undertakes transformation
of phases <span>from a </span></span>liquid<span> <span>to a </span></span>gas<span> <span>and vice versa.</span></span>
Answer:
w = 7.89 10⁻² rad/s
Explanation:
We will solve this exercise with the conservation of the annular moment, let's write it in two moments
Initial. With the insect in the center
L₀ = I w₀
End with the bug on the edge
= I w + 
w
The moments of inertia are
For a rod
I = 1/3 M L²
For the insect, taken as a particle
I = m L²
The system is formed by the rod and the insect, this is isolated, therefore the external torque is zero and the angular momentum is conserved
L₀ =
I w₀ = I w + w
w = I / (I + ) w₀
w = I / (I + m L²) w₀
Let's calculate
w = 1.43 10⁻³ / (1.43 10⁻³ + 5 10⁻³ 0.620²)² 0.185
w = 1.43 10⁻³ / 3.352 10³ 0.185
w = 7.89 10⁻² rad/s
