Nick lives in area that has a south-facing slope. the temperature in his area is always high. which of these abiotic factors is responsible for high temperatures in nick’s area?
a) nutrients
b) soil
c ) water
d) topography

Answer : (D) topography

Explanation :

Nick lives in an area that has a south-facing slope. The temperature in his area is always high. This implies that Nick's place gets maximum sun rays.

Abiotic factors are the things or the conditions which affect our ecosystem or organisms in it.

Topography means the full description of any place. It is the study of the properties of land surfaces. So, the topography is responsible for high temperatures in Nick’s area

Out of the given options, correct one is (D) "topography".

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
