Built around the concept in “What is the SI unit of plane angle?”, this bilingual General Science item checks whether a learner can connect a scientific term with its exact property, mechanism or function. The verified answer is Radian.
The concept tested here leads specifically to Radian. Radian is the SI supplementary unit of plane angle. Physics requires attention to the measured quantity, governing principle and unit. The alternatives Revolution, Degree and Steradian are legitimate scientific terms, but each belongs to a different function, property, material or context. If the topic involves the human body, check organ and function; in chemistry, check composition and reaction; in physics, check quantity and unit; and in environmental science, check layer and process.

Radian. Radian is the SI supplementary unit of plane angle.
Use the defining property and mechanism from physics.
Revolution, Degree, Steradian belong to different functions, properties or contexts.
Connect “What is the SI unit of plane angle?” with Radian and the supporting mechanism.
General Science covers basic concepts in Physics, Chemistry, Biology, and Earth Science. It is an important section in competitive exams like SSC CGL, UPSC Prelims, Railway NTPC, and Defence exams. Questions include scientific laws, inventions, human body systems, chemical reactions, and everyday science phenomena. NCERT Science books from Class 6 to 10 are recommended.
Newton's Three Laws of Motion: 1) First Law (Law of Inertia) - An object remains at rest or in uniform motion unless acted upon by an external force. 2) Second Law - Force equals mass times acceleration (F=ma). 3) Third Law - For every action there is an equal and opposite reaction. These laws are fundamental to Physics and frequently asked in SSC CGL, Railway, and NDA exams.
