The correct answer is C. American intervention remains unpopular among some Afghan groups.
Explanation
An argument is a way to express oral or written reasoning to demonstrate the validity or invalidity of an estate through its relationship with a set of conclusions. Therefore, it can be said that an argument to demonstrate opposition to the establishment of US troops in Afghanistan is "C. American intervention remains unpopular among some Afghan groups" because this shows a negative conclusion of said action.
I think its called observational learning
(If i get this wrong Im srry)
Answer:
a) horizontally
Explanation:
If the sewage sludge is disposed of into the deep water , then the density gradient separates the surface water from the deep water,
the internal waves transport wastes horizontally .
<u>When the transport of the particles is dominated by the tides ,wind and the density gradients, the movement is essentially in horizontal direction whereas the vertical transport of the particles is mainly driven by gravity and also by some other processes that occur at the sediment-water interface.</u>
Answer:
B and C
Explanation:
B. In a given rock sample, the amount of Silicon-32 isotopes gets divided in half about every 170yrs.
This is the concept of half-life. Half life is the time take for half of a radioactive isotope to disintegrate. The shorter the half life the faster the isotope disintegrates.
From the question, we were told that it would take 170yrs for half of the isotope of Silicon to disintegrate to Phosphorus. This is the half life.
C. The half life can be used to determine the amount of Si-32 that has decayed from the time closure temperature was reached.
The closure temperature is very important in radioactivity. It is the temperature at which a system has cooled and there is no resulting disintegration of parent and daughter isotopes.
From first order kinetics, we know that the rate at which radioactive elements decay at any time is directly proportional to the number of radioactive atoms present. A knowledge of the half life helps to figure out the number of atoms that has decayed in time.
