A hydrogen bomb is a nuclear bomb, like an atomic bomb, where the explosive energy comes from as nuclear reaction.
A hydrogen bomb is about fusion — fusing atomic nuclei together to combine into bigger ones.
A hydrogen bomb, or a thermonuclear bomb, contains a fission weapon within it but there is a two-stage reaction process.
The U.S. used two atomic bombs in World War II against Japan, Then, in 1952 and 1954
In particular, monitors will be looking for isotopes of a gas called xenon, which is typically present in H-bomb reactions.
Answer : As the temperature of a medium increases, the speed of the sound wave increases because the particles bump into each other more often.
Explanation :
The dependency of the speed of the sound wave and the temperature of the medium is :
Where
= ratio of specific heat
R is gas constant
T is the temperature
The speed of the wave is directly proportional to the temperature. As the temperature of a medium increase, the speed of the sound increase. The particles start vibrating faster. Hence, they bump into each other.
Hence, the correct option is (A).
