Answer: The amount of light that enters the pupil is controlled by the Iris
Explanation:
Answer:
9.8 m/s^2
Explanation:
This is a constant that you should memorize
Answer:
0.1308
Explanation:
To keep the rider from sliding down, then the friction force
must at least be equal to gravity force 


where μ is the coefficient, N is the normal force acted by the rotating cylinder, m is the mass of a person and g = 9.81 m/s2 is the gravitational acceleration.
According to Newton's 3rd and 2nd laws, the normal force would be equal to the centripetal force
, which is the product of centripetal acceleration
and object mass m

Therefore


The centripetal acceleration is the ratio of velocity squared and the radius of rotation

Therefore

Answer:
W = 0.11J
P = 0.0186W
Explanation:
Please see attachment below.
The object will sail away in a straight line ... continuing in the same direction it was going when the centripetal force stopped.
