A very luminous star light of high temperature is incident on an opaque, dense cold interstellar medium consisting primarily of neutral hydrogen. Seen from Earth, the observed stellar light will primarily Group of answer choices be observed only in X-ray band. be characterized by just the continuous spectrum. exhibit many absorption lines with the continuous radiation. exhibit many emission lines and the continuous radiation. be transmitted through the medium without any effects.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

i think the answer is a, hope this : )

answer; how far out of place which the object finished relative to the starting location;

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.
