Artificial gravity is produced in a space station by rotating it, so it is a noninertial reference frame. the rotation means that there must be a centripetal force exerted on the occupants; this centripetal force is exerted by the walls of the station. the space station in arthur c. clarke's 2001: a space odyssey is in the shape of a four-spoked wheel with a diameter of 150 m. if the space station rotates at a rate of 2.45 revolutions per minute, what is the magnitude of the artificial gravitational acceleration provided to a space tourist walking on the inner wall of the station?

Explanation:

centripetal acceleration = ω² R

ω is angular speed of rotation and R is radius of circular path

ω = 2π n

n is no of rotation per sec

= 2.45 / 60

ω = 2π x  2.45 / 60

= .2564 rad / s

centripetal acceleration = ω² R

= .2564² x 150/2

= 4.93 m /s²

gravitational acceleration provided = 4.93 m /s²

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
