Arnold makes a chart to summarize what happens when light interacts with matter and is reflected. a 2 column by 4 row table. column 1 is titled type of interaction and contains the following entries: specular reflection, diffuse reflection, scattering. column 2 is titled description and contains the following entries: occurs when light strikes smooth surface, follows the law of reflection, reflected rains move in the same direction, occurs when light strikes rough surface, follows the law of reflection, reflected rays move in different directions, occurs when light strikes particles in atmosphere, follows the law of reflection, short wavelengths are scattered the most which best describes arnold’s error? in specular reflection, reflected rays move in the same direction. in scattering, short wavelengths are scattered the least. in diffuse reflection, reflected rays move in the same direction. the law of reflection is not followed in scattering.
the law of reflection is not followed in scattering.

f=ma newton

f=100x2.5=250n

i think the answer would be reserve.

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.
