By what i know i think that the answer would be A a homogeneous mixture.
PM me for full answer, please. If it's not too late.
Answer:
<u>EFFECTS: ( doughts)</u>
- There would be less water in the river for you and other people who live along the river to use.
- If we use too much water during times of normal rainfall, we might not have enough water when a drought happens.
<u>EFFECTS:( FLOODS)</u>
- The immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases.
- power plants, roads and bridges are damaged and disrupted, some economic activities may come to a standstill, people are forced to leave their homes and normal life is disrupted.
How to prevent from flooding is :
- Construct buildings above flood levels.
- Tackle climate change
How to prevent from droughts :
- drought trends that may occur based on statistical and actual weather forecasts.
- In the U.S., the U.S. Drought Monitor provides a day-by-day visual of the drought conditions around the country.

Answer:
The number of revolutions is 44.6.
Explanation:
We can find the revolutions of the wheel with the following equation:
Where:
: is the initial angular velocity = 13 rad/s
t: is the time = 8 s
α: is the angular acceleration
We can find the angular acceleration with the initial and final angular velocities:
Where:
: is the final angular velocity = 57 rad/s
Hence, the number of revolutions is:
Therefore, the number of revolutions is 44.6.
I hope it helps you!
