<span>The student's experiment is modeled after mass wasting, which is also known as mass movement or slope movement. One of the factors of mass wasting is gravity. The water from the hose weighs down the soil and causes the clumps of soil to move downward through the stack of rocks.</span>
I’m pretty sure you just add AB to BC, since they are all points on a line, those two segments add together to get the value of AC. Therefore, 12+16= 28, so AC=28
Answer:
<u>scientist general conduct test and analysis by experimenting data that leads to formation of hypothesis for the study.</u>
