Answer:

Step-by-step explanation:

The maximum change happens when all 500 people moves form outer surface to the station center. When all of them are at the surface, the total moment of inertia is:

$I = I_s + 500I_p = 3*10^9 + 500m_pr_p^2=3*10^9 + 500*70*82.5^2=3.24*10^9$

When they are at the axis, the total moment of inertia is only the station's, which is $3*10^9$

By the law of angular momentum conservation:

$I_1\omega_1 = I_2\omega_2$

$\omega_2/\omega_1 = I_1/I_2 = \frac{3.24*10^9}{3*10^9} = 1.08$

So the angular speed changes by 0.08 of itself, or 8%

HELPPPPPPPP why is the answer D?

Marysya12 [62]

We can solve for x by raising both sides to the -3 power (which is the reciprocal of -1/3):

(c^-1/3)^-3 = x^-3
c^1=x^-3
c=x^-3

Since the exponent on the x is a negative, we have to move it to the denominator to make it positive:

c= 1/x³
