Answer:
If a neutral atom gains electrons, then it will become negatively charged. If a neutral atom loses electrons, then it become positively charged.
It is important to properly balance a centrifuge because an unbalanced machine can damage the rotor, cause catastrophic damage to the machine itself, or even injure or kill lab personnel working in the room. Balancing a centrifuge involves spreading the weight of the samples across the entire rotor.
We know that:
Solving for Distance:
- Distance = Work / Force
- Distance = 1220 J / 280 N
<h3> Distance = 4.36 m </h3>
From the definition of apparent magnitude, we know that:

where:
m = apparent magnitude
F = corresponding flux
We also know that the flux is given by the formula:

where:
L = luminosity
d = distance
Therefore:

Now, let's apply these formulae to the same star (therefore, same luminosity), using apparent magnitude and absolute magnitude (which is defined as the apparent magnitude the star would have if it were at a distance of 10pc):

Now, let's solve for m:

= <span>

</span>
= 13
Hence,
the apparent magnitude of the star would be m = +13
