How has scientific experimentation affected the model of an atom? the atomic model has become more accurate because of this experimentation. the atomic model has become a less accurate representation of the actual atom. we understand less about the atom due to these experiments. we are less able to design an accurate model as a result of these experiments.

the answer is - the atomic model has become more accurate because of this experimentation.

The atom is made of protons, neutrons and electrons

Most of the space is taken up by the area where the electrons exist

The protons and neutrons are in the core of the atom - called the nucleus

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.

there are no atoms
