a dwarf planet is a?

1.small, rocky object that orbits the sun and is usually found in a belt between the orbits of mars and jupiter.
2.small object made of ice and dust that orbits the sun and forms a coma as it approaches the sun.
3.round object that orbits the sun but lacks the ability to clear the neighborhood around its orbit.
4.meteoroid that burns up in earth’s atmosphere, producing a streak of light.

c. magnitude and direction

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.
