The twin who is "whisked away" at high speed and then returns (presumably at the same speed) will have aged less, by a factor of sqrt[1-(0.9)^2] = 0.436
<span>He will have aged 28.3 Earth years.
Hope this helps.</span>
Answer:
The ratio is 4
Explanation:
The moment of inertia of a solid sphere about a central axis is:
With m the mass and r the radius of the sphere.
For the smaller sphere with mass M and radius R the moment of inertia is:
(1)
For the bigger sphere with mass M and radius 2R the moment of inertia is:
(2)
The ratio between larger of the larger sphere's moment of inertia about a central axis to that of the smaller sphere is the ratio between (2) and (1):
The term cancels, so:
