The assembly of two 5-kg spheres is rotating freely about the vertical axis at 40 rev/min with . if the force f which maintains the given position is increased to raise the base collar and reduce to , determine the new angular velocity . also determine the work u done by f in changing the configuration of the system. assume that the mass of the arms and collars is negligible.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region
