The Sun’s tоtаl energy оutput is 3.85×1026 wаtts, аnd 1 watt is 1 Jоule/second. Assume 4.3×10−12 J is released from each proton–proton chain of reactions. Use the energy yield from the proton–proton chain to determine how many proton–proton chain fusion cycles must be happening each second in the solar core.
