Shane Reams was a troubled youth. He frequently stole from his neighbor's garages, which made his mother very angry. She decided to practice tough love and asked her son to turn
himself in. By the time that he was arrested for being involved in a n$20 drug sale (he was the
lookout), he already had two counts of burglary on his record. Under California's three-strikes
law, he received a life sentence because this was his third offense. According to his mother, he
lost hope because of the life sentence and joined a gang during his first several years in prison.
(Eventually, knowing that his mother was campalgħing for his release, he later took many
college courses in sociology and psychology and repented for his earlier criminal activity.)
Does the sentence fit the crime?
Does harsh punishment help the person who gets in trouble?
What lesson does the punishment teach?
What other punishment could have been in place to avoid this tragedy?
What could his mother have done differently?
What could Shane have done differently?

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
