When you look through a sheer curtain at a distant stres lamp, you see a pattern of colored spots of light. this occured solve the suppose a piece heat of fusion of 333°c. calcula bismuth ars 1. a polarization of light in scattering and partial absorption by the threads. b. interference of light waves that pass through the threads with light waves that pass through the openings between the threads. refraction of light waves differentially in the cylindrical threads. (d. diffraction of light waves passing through the two dimensional pattern of openings between the threads. e. reflection of light waves by the sides of the threads.

it has to be b, about 97 percent.

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.
