Please help me this simple question. Please answer questions 1 and 2
5.7 Questions 1. What is a neutrino? What scientific observations led to its prediction? 2. Studying neutrinos helped to explain how our Sun works but led to changes in theories of particle physics. How is this process consistent with the scientific process? How can details about a theory be adjusted without undermining other discoveries made through the theory's predictions 3. Explain how the theory of neutrino oscillations helps to explain the missing electron neutrinos from the Sun. 4. Building large detectors underground can have an impact on the environment around the detector site. Do you think the knowledge we gain from studying neutrinos is worth the environmental impact? Explain your reasoning. ICIExplanation / Answer
Q.1 A neutral subatomic particle with a mass close to zero and half-integral spin, which rarely reacts with normal matter. Three kinds of neutrinos are known, associated with the electron, muon, and tau particle.Neutrinos are one of the fundamental particles which make up the universe. They are also one of the least understood. Neutrinos are similar to the more familiar electron, with one crucial difference:neutrinos do not carry electric charge.
What leads to the prediction:-
The first experiment to attempt to detect electron neutrinos from the sun was conducted by a detector in the bottom of the Homestake mine in South Dakoda in 1968. However they detected only neutrinos about twice a week. It was predicted however that the detector should find about one of the 1016 solar neutrinos a day.
1962 - Experiments at Brookhaven National Laboratory and CERN, the European Laboratory for Nuclear Physics make a surprising discovery: neutrinos produced in association with muons do not behave the same as those produced in association with electrons. They have, in fact, discovered a second type of neutrino (the muon neutrino).
1968 - The first experiment to detect (electron) neutrinos produced by the Sun's burning (using a liquid Chlorine target deep underground) reports that less than half the expected neutrinos are observed. This is the origin of the long-standing "solar neutrino problem." The possibility that the missing electron neutrinos may have transformed into another type (undetectable to this experiment) is soon suggested, but unreliability of the solar model on which the expected neutrino rates are based is initially considered a more likely explanation.
Q.2 Yes clearly this process is consistent with the scientific process because in scientific process falsification and modification are two very important traits. So this new concept have modified the existing theories.
Through the modification a theory is adjusted without undermining other discovering made through the theory's prediction.
There are many other evidences that prove this fact for example Eienstien's Theory of relativity also changes the existing concepts.
