Answer:
A .Southern Hemisphere Low pressure
Step-by-step explanation:
When considering centrifugal force, The southern Hemisphere Low pressure has sign coefficient of 1. The rotation of Earth causes the centrifugal acceleration. The magnitude of centrifugal force is given by mv^2r.
Where m is mass of rotating body , v is the linear velocity and r is the radius of rotation. The centrifugal force always works outside the center of the circular motion.
