The meter that is used to measure the distance moved by the vehicle is known as:
Detailed Explanation:
Odometer is the instrument that measures the total distance traveled by a vehicle, displayed in kilometers or miles on the dashboard.

Which of the following acids is secreted in the stomach?
Detailed Explanation:
Hydrochloric acid (HCl) is secreted by parietal cells in the gastric glands of the stomach.
It activates pepsinogen to pepsin for protein digestion, kills ingested bacteria, and maintains a pH of 1.5–3.5 in the stomach.
Dalton's atomic theory successfully explained:
i. Law of conservation of mass
ii. Law of constant composition
iii. Law of radioactivity
iv. Law of multiple proportion
Detailed Explanation:
Dalton's atomic theory (1808) explained three fundamental laws of chemical combination:
✅ Law of conservation of mass: Atoms are neither created nor destroyed in reactions, so total mass remains constant.
✅ Law of constant composition: A compound always contains the same elements in fixed proportions by mass.
✅ Law of multiple proportions: When two elements form multiple compounds, mass ratios are simple whole numbers.
❌ Law of radioactivity: Radioactivity (discovered by Becquerel, 1896) involves nuclear changes, not explained by Dalton's indivisible atom concept.
