What is the speed of light in a vacuum?
Answer: 300,000 km/s. The speed of light in a vacuum is about 299,792 km/s, often rounded to 300,000 km/s. It is a fundamental constant of physics, denoted "c".
Which planet is nicknamed the "Red Planet"?
Answer: Mars. Mars is nicknamed the "Red Planet" because of the iron oxide (rust) found in abundance on its surface, which gives it its characteristic colour.
Who formulated the theory of general relativity?
Answer: Albert Einstein. Albert Einstein published his theory of general relativity in 1915. It describes gravitation as a curvature of spacetime caused by mass and energy.
Which chemical element is the most abundant in the universe?
Answer: Hydrogen. Hydrogen is the most abundant element in the universe, making up about 75% of visible ordinary matter. Stars, including the Sun, work mainly by fusing hydrogen nuclei to form helium in a process called nuclear fusion.
How many chromosomes does a normal human cell contain?
Answer: 46. A normal human cell contains 46 chromosomes, organised in 23 pairs. Of these, 22 pairs are autosomes and one pair is the sex chromosomes (XX in women, XY in men). Reproductive cells (gametes) contain only 23 chromosomes.
