Spectrophotometry is a laboratory technique
that can be performed first to check if there is presence of arsenic mixed in
with Gatorade. In spectrophotometry, arsenic concentration will be measure in a
specific solution by calculating the amount of light absorbed by inorganic
arsenic.
Various analytical reagents are used such as molybdate reagent and variamine blue
as a chromogenic reagent where a violet colored indicates presence of arsenic.
Furthermore,
new analytical reagents has been development and proposed like vanillin-2-
amino nicotinic acid (VANA) and 2, 4-Dihydroxy benzophenone-2-amino thiophenol
(BPBT). These are used for direct non-extractive spectrophotometric determination of arsenic. The reagent
reacts with arsenic in acidic
medium to form light greenish yellow colored.
Answer:
The answer is the third option, the minimum force required to overcome static friction and move an object.
Explanation:
The first choice is talking about an object moving, and anything moving relates to <em>kinetic </em>friction, not static friction. I don't think it's the fourth option because, even with the net force being 0, the object could still be moving (again relating to kinetic friction).

Answer:</h3>
0.82 m/s²
<h3>
How?</h3>
Though its gravity is weak compared to earth, Eris has the strongest gravity out of all the dwarf planets: 0.82 m/s².
<h3>
How Is Eris Important?</h3>
Eris is the <u>largest</u> dwarf planet in the Solar System, and the <u>ninth largest body orbiting our Sun.</u> The discovery of Eris was so important because it was a celestial body larger than Pluto, which forced astronomers to consider, for the first time in history, what the definition of a planet truly is!
Hope this helps you!! :D
Answer; I say both
Explanation: becuase if you take all air away then they will fall at the same time
