Concept explainers
(a)
To Explain: Whether the given reaction is possible or not.
(a)
Answer to Problem 49GP
The given reaction is not possible because charge is not conserved.
Explanation of Solution
The given reaction is,
For the given reaction, the conservation law should be checked, such that
Charge
Charge is not conserved
Conclusion:
Hence, charge is not conserved by the reaction. So, above reaction is not possible.
(b)
To Explain: Whether the given reaction is possible or not.
(b)
Answer to Problem 49GP
The given reaction is possible through the strong interaction.
Explanation of Solution
The given reaction is,
For the given reaction, the conservation law should be checked, such that
Charge -1 +1 = 0 0
Spin
Baryon number 0 1 = 1 0
Lepton number 0 0 = 0 0
Strangeness -1 0 = -1 0
Charge is conserved, baryon number and lepton number are also conserved, and strangeness is also conserved.
Conclusion:
Hence, all conservation laws are followed by the reaction. so, above reaction is possible.
(c)
To Explain: Whether the given reaction is possible or not.
(c)
Answer to Problem 49GP
The given reaction is not possible because strangeness is not conserved.
Explanation of Solution
The given reaction is,
For the given reaction, the conservation law should be checked, such that
Charge 1 0 = +1 0 0
Spin
Baryon number 0 1 = 1 0 0
Lepton number 0 0 = 0 0 0
Strangeness
Charge is conserved, baryon number and lepton number are also conserved, but strangeness is not also conserved.
Conclusion:
Hence, the above reaction is not possible.
(d)
To Explain: Whether the given reaction is possible or not.
(d)
Answer to Problem 49GP
The given reaction is not possible because strangeness is not conserved in the given reaction but it is possible through the weak interaction.
Explanation of Solution
The given reaction is,
For the given reaction, the conservation law should be checked, such that
Charge 1 = 0 0 0
Spin
Baryon number 0 = 0 0 0
Lepton number 0 = 0 0 0
Strangeness
Strangeness is not conserved.
Conclusion:
Hence, reaction is not allowed but possible through the weak interaction.
(e)
To Explain: Whether the given reaction is possible or not.
(e)
Answer to Problem 49GP
The given reaction is possible through the weak interaction.
Explanation of Solution
The given reaction is,
For the given reaction, the conservation law should be checked, such that
Charge 1 = +1 +0
Spin 0 = +1/2 -1/2
Baryon number 0 = 0 + 0
Lepton number 0 = -1 +1
Strangeness 0 = 0 0
Charge is conserved, baryon number and lepton number are also conserved, and strangeness is also conserved but it is possible through the weak interaction.
Conclusion:
Hence, all conservation law are followed by the reaction. so, above reaction is possible.
