RRB Group D 2022 CBT General Science – Chemistry/ Physics/ Biology Questions with Answers

Question related to Force:

Answer: In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Question related to Atomic Number:

Answer: The atomic number or nuclear charge number of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number or the number of protons found in the nucleus for every atom of that element.

Question related to Electricity

Question related to Photosynthesis:

Answer: Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
