Step-by-step explanation:
Using the trigonometric identities
tan(90 - x) = cotx , cotx =
Given
tan1tan2tan3....................... tan87tan88tan89
= tan1tan2tan3............... tan(90-3)tan(90-2)(tan90 - 1)
= tan1tan2tan3.............. cot3cot2cot1
= tan1cot1tan2cot2tan3cot3 ........................
= 1 × 1 × 1 ×....................... × 1
= 1
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%
