When considering centrifugal force, which of the below scenarios has a sign coefficient of 1?

A. Southern Hemisphere Low pressure

B. Northern Hemisphere Low pressure

C. Northern Hemisphere High pressure

D. Western Hemisphere Low pressure

A. Southern Hemisphere Low pressure

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.
