a) 2 million K
b) 5 million K
c) 10 million K
d) 15 million K

Answer 1

The critical temperature to initiate the proton-proton cycle in the core is 15 million K (d)

Step-by-step explanation:

The critical temperature to initiate the proton-proton cycle in the core is 15 million K (d) .The proton-proton cycle, which is a series of nuclear reactions that power stars like the Sun, requires a critical temperature of 10 million Kelvin to initiate.
