Answer: a. perigee speed
Explanation:
Firstly, we must define what is Perigee and Apogee:
The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest.
</u>
On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum.
</u>
Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.
Answer:
Chemical weathering changes the soil pH and affects the crops that grow on them
Explanation:
Chemical weathering refers to the breaking down of rocks through chemical reactions.
Whenever rocks which are chemically active come in contact with acidic rain, they react to form new compounds. These new compounds formed usually have different properties from their parent rocks.
As a result of chemical weathering, changes in the soil properties can occur such as its pH. These changes will affect the nutrients which can be found in them, thus affecting farming practices on such soil.
