It’s not a or b or c or d it’s the only one
Answer:
The correct answer is - nuclear fission.
Explanation:
In the given diagram, the reaction is a graphical representation of the nuclear fission of one nucleus of Uranium 235 into two nuclei of Kr with three neutrons that leads to a chain reaction and releases a huge amount of energy and grow out of control.
With every fission, there are two neutrons emitted which results in splitting more nucleus into two nuclei and keep on growing and never die out. The amount of energy also keeps on growing with an increase in the reactions and fission. This reaction is used to generate electricity and nuclear weapons.
Answer:
: cathode rays
a beam of electrons emitted from the cathode of a high-vacuum tube.
During the 1880s and '90s scientists searched cathode rays for the carrier of the electrical properties in matter. Their work culminated in the discovery by English physicist J.J. Thomson of the electron in 1897.
Answer:
A:temperature
Explanation:
The temperature cannot be determined by looking at the spectra of the star due to lack of the equipment for its measurement. <em>On the other-hand, the remaining statements like the distance from earth, movement towards or away from earth can be determined.</em>
