Drag each tile to the correct location. A scientist on Earth is studying the light emitted by a number of celestial objects. To determine whether each object is
moving away from or toward Earth, he analyzes their spectral lines and records how they have shifted (in nm). Use the
scientist's measurements from the table and the image of the visible light spectrum to determine whether each object is
moving toward or away from Earth.

what question you dont ask a question

explanation:

the answer is a)

mark brainliest

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

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.
