A Gyroscope Has a Moment of Inertia of 0

question 17

Multiple Choice

A gyroscope has a moment of inertia of 0.140 kg m² and has an initial angular speed of 12.0 rad/s. If a lubricant is applied to the bearings of the gyroscope so that frictional torque is reduced to 2.00 *10^-2 N
M, then in what time interval will the gyroscope coast from 12.0 rad/s to zero?

• A) 150 s
• B) 105 s
• C) 90.0 s
• D) 84.0 s

Definitions:

Parental Species

The original species from which new species originate, often investigated in the context of evolutionary biology.

Alloploidy

A type of polyploidy where the chromosome sets come from different species, leading to the creation of hybrid organisms.

Slow Speciation

The gradual process by which new species are formed over long periods of time, often involving gradual adaptations to environmental changes.

Allopolyploids

Organisms that contain multiple sets of chromosomes derived from different species, typically as a result of hybridization followed by chromosome doubling.
