Which sentence contains a nonrestrictive clause and is punctuated correctly? the teacher packed picnic lunches for all the students—which they loved—and ate lunch outside with them at recess. the teacher packed picnic lunches for all the students which they loved—and ate lunch outside with them at recess. the teacher packed picnic lunches (for all the students) which they loved and ate lunch outside with them at recess. the teacher packed picnic lunches for all the students which they loved and ate lunch outside with them (at recess).

Answer;

The teacher packed picnic lunches for all the students—which they loved—and ate lunch outside with them at recess.

Explanation;

A nonrestrictive clause is a type of adjective clause that provides additional information about a word whose meaning is already clear. Nonrestrictive clauses often begin with the word which and are always set off with commas.

In this case, A is correct because after students the appropriate punctuation would be a coma but in this case its a line. B is incorrect since after "student's" it should have a line/comma. C is incorrect since after loved it should have a comma/line. D is incorrect since there is no correct punctuation.

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.
