... 3. In the fusion of four protons into helium, 4.7 × 10−26 grams of matter is turned into energy. How much energy does this amount of matter produce? E=∆mc2 = (4.7 × 10−26 ) × (3 × 1010 )2 grams-cm2 /sec2 (erg)= 42.3 × 10−6 ergs 4. How long will a 4M star with L = 5000L spend on the main-sequence? ...
