Why is it important to have a balanced centrifuge?
ratelena [41]

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.

A motor exerts a 280 N force and does 1220 J
finlep [7]

We know that:

  • Work = Force × Distance

Solving for Distance:

  • Distance = Work / Force
  • Distance = 1220 J / 280 N
<h3>        Distance = 4.36 m </h3>

Star a has an absolute magnitude of 8. what is its apparent magnitude at a distance of 100 pc
tresset_1 [31]
From the definition of apparent magnitude, we know that:
m_{1} - m_{2} = -2.5Log( \frac{F_{1}}{F_{2}} )
where:
m = apparent magnitude
F = corresponding flux

We also know that the flux is given by the formula:
F =  \frac{L}{4 \pi  d^{2} }
where:
L = luminosity
d = distance

Therefore:
\frac{F_{1} }{F_{2}} = (\frac{L_{1} }{4 \pi d_{1}^{2} })(\frac{4 \pi d_{2}^{2} }{L_{2} }) \\ =  \frac{L_{1}d_{2}^{2}}{L_{2}d_{1}^{2}}

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):
m - M = 2.5 Log ( \frac{d}{10pc})^{2}

Now, let's solve for m:
m = M + 2.5 Log ( \frac{d}{10})^{2}
= <span>8 + 2.5 Log ( \frac{100}{10})^{2}</span>
= 13

Hence, the apparent magnitude of the star would be m = +13
