General Relativity describes gravity as a manifestation of what fundamental property of spacetime?
π‘ Explanation:General Relativity, published by Albert Einstein in 1916, fundamentally describes gravity not as a force acting between masses (Newton's view), but as the curvature (or geometry) of the four-dimensional fabric of spacetime caused by the presence of mass and energy. Objects then follow the 'straightest' path (geodesics) through this curved spacetime, which we perceive as the effect of gravity. The exchange of gravitons (Option A) is the theoretical description of gravity within the framework of quantum field theory, which is a separate approach from General Relativity.

In classical mechanics, which of Newton’s three Laws of Motion is quantitatively expressed by the formula F = ma (Force equals mass times acceleration)?
π‘ Explanation:Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. This fundamental relationship is summarized by the equation F=ma.
