The isotope of uranium capable of sustaining chain reaction is U-235.
The isotope of uranium capable of sustaining chain reaction is U-235.
Answer: Option D. -> Uranium - lead method
The Uranium Lead Method, also known as the U-Pb method, is one of the most ancient and reliable radiometric dating methods. It is used to date rocks and crystals that were formed more than a billion years ago. It has a range of dating samples that are about 1billion to 4.5billion years old. It has a precision rate of 0.1−1 percent.

Answer: Option C. -> Rutherford
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.

Absorption of corresponding wavelengths by the outer layers of the sun.
Answer: Option A. -> A molecule
Smallest particle of an element or a compound which is capable of independent existence is called molecule. A molecule is formed when two or more atoms join together chemically.

Answer: Option B. -> Paper
Wood is the main raw material for the manufacture of paper.
Wood is the main raw material for the manufacture of paper.
Answer: Option D. -> Communication
Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.
