Q6. Which 19th-century German physicist, known for his work on the photoelectric effect, was a key figure in the development of quantum theory and was awarded the Nobel Prize in Physics in 1921?

Explanation: Albert Einstein was awarded the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect, which he published in 1905. His work demonstrated that light behaves as discrete packets of energy (quanta/photons), a key foundation of quantum theory.

Q7. Which of the following scientists is credited with inventing the first practical lightning rod?

Explanation: Benjamin Franklin's invention of the lightning rod in 1752 helped protect buildings from lightning strikes by attracting the electrical charge and directing it harmlessly into the ground.

Q8. Which American industrialist developed the first modern moving assembly line for automobile manufacturing, revolutionizing mass production?

Explanation: Henry Ford developed the first moving assembly line for automobile manufacturing in 1913 at his Highland Park plant, dramatically reducing the time to build a Model T from 12 hours to about 90 minutes. While Karl Benz invented the gasoline automobile in 1886 and Ransom Olds developed an earlier stationary assembly line, Ford's moving assembly line revolutionized industrial mass production.

Q9. Which of the following scientists is credited with inventing the first successful polio vaccine?

Explanation: Jonas Salk developed the first inactivated poliovirus vaccine in the 1950s, leading to a significant decline in polio cases worldwide.

Q10. Which 17th-century English physicist is credited with the discovery of the properties of magnetism and the invention of the first magnetic compass?
