Use the periodic table to determine which of the following would be an isotope of bromine (br) check all that apply

The isotopes of a element is defined as the atoms having same atomic number and different mass number.

As per periodic table Br has atomic umber Z=35 and its atomic mass is given as 79.904 or 79.

As per the question nothing has been mentioned .

so all the atoms whose atomic number will correspond to 35 will be considered as the isotope of bromine.

Generally Bromine exhibits two isotopes which are stable.The isotopes are Bromine-81 and Bromine-77.

Some times during the process of gamma decay Bromine forms many radio isotopes also which are unstable.

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.
