RRB Group D 2022 CBT General Science – Chemistry/Physics/Biology Questions with Answers |
Force related question:
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 speed, that is, speed up. The force can also be intuitively described as a push or a pull. A force has both magnitude and direction, so it is a vector quantity.
Question related to the 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 number of protons or the number of protons found in the nucleus for each 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.

Methane formula:
Answer: CH4
Question related to the mirror image of the concave lens:
Answer: When the concave mirror is placed very close to the object, a virtual and enlarged image is obtained and if we increase the distance between the object and the mirror, the size of the image is reduced and real images are formed.
Bleaching Powder Formula:
