In an amusement-park ride, riders stand with their backs against the wall of a spinning vertical cylinder. The floor falls away
seraphim [82]

Answer:

90.78 rev/min

Explanation:

In first place, we have to do the force balance to determine the minimum angular speed required to avoid slipping. The forces acting here are friction and the force due to circular movement, that is centripetal force. Then, we have:

f=ma_{c}

μmg=mRω^2

ω=\sqrt{\frac{μg}{R} } \\

Then, replacing the given values in the expression we have the following result:

ω=1.51 rev/s*60s=90.78 rev/min

What is NOT a 21st-century skill that can help a person thrive today?
Soloha48 [4]

Ability to memorize and regurgitate information on tests is the skill that can’t help a person to thrive today in this modern 21st century.

Answer: Option D

<u>Explanation:</u>

Thriving in this modern 21st century is not as easy as it used to be in the early 20th and 19th centuries.  So there is a need to develop skills like implementing one's knowledge to real-world structures which will sure help a person to understand and explore more.

Statement B also will sure be helpful to survive in modern society and a person can also improve his/her critical thinking, problem solving and other skills to thrive through this century.

But even though memorizing and regurgitating information can help you get good grade it will never be that helpful in other ways, So option D can be concluded as the right answer.
