Answer:
8%
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:

When they are at the axis, the total moment of inertia is only the station's, which is 
By the law of angular momentum conservation:


So the angular speed changes by 0.08 of itself, or 8%
Answer:
x=0
Step-by-step explanation:
solve for x by simplifying both sides of the equation, then isolating the variable. which got me x=0
Answer:
The new price = $718. 8
Step-by-step explanation:
Original Price = $599
Given that the increase is 20%.
i.e.
Thus,
The amount of 20% Percentage increase = 20/100 × 599
= 0.2 × 599
= $119.8
Therefore,
New price = Original price + 20% increase amount
= 599 + 119.8
= $718. 8
Therefore, the new price = $718. 8
