Scientists could investigate this idea by making cathode ray tubes out of different materials to see if the ray was the same.
C look at how many oxygen, nitrogen’s, and hydrogens there are
<span>Oxygen and Nitrogen would be the most similar of the elements listed, because they are the closest in the periodic table. This isn't a very good reason for anything, but the two do have some similar properties. They are both non-metals, they are both highly electronegative, they are both diatmoic gasses in their natural states, they have a similar number of valence electrons, they are both generally oxidizing agents. Oxygen and Chlorine are also quite similar, but not quite as similar as Oxygen and Nitrogen.</span>
Average speed = total distance / total time.
That's 172 km / 5 hr = 34.4 km//hr
I think the answer is B because juice has a higher density than water
