3 ways that asteroids are like planets

1.Asteroids aren't all round like planets. They have jagged and irregular shapes.

2.Some asteroids are hundreds of miles in diameter, but many more are as small as pebbles.

3.Most asteroids are made of different kinds of rocks, but some have clays or metals, such as nickel and iron.

Explanation:

it is simple really  u just need to remember that astorids do not orbit a sun they crash into  things like planets  and mess them up really bad  if they   hit our sun which might happen  it will just burn up because our sun is so hot that it can burn stuff  if a astorid hits earth it wont be to bad for our earth at all it might cause some damage but we will be fine.      

none, its a machine

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.
