1. TUTORIAL 10.4 TENAGA NUKLEAR NUCLEAR ENERGY

2. E = mc 2 7.81 x 10 -13 = m (3 x 10 8 ) 2 = 8.68 x 10 -30 kg

3. E = mc 2 2.9 x 10 -11 = m ( 3 x 10 8 ) 2 = 3.22 x 10 -28 kg

4. Alpha decay / pereputan alfa Unstable nucleus / nukleus yang tidak stabil

5. 226.025 – [222.018 + 4.003] = 0.004 u = 0.004 x 1.66 x 10 -27 = 6.64 x 10 -30 kg E = mc 2 = (0.004 x 1.66 x 10 -27 ) x (3 x 10 8 ) 2 = 5.976 x 10 -13 J

6. No of proton + no of neutron / no proton + no neutron 3 Nuclear fusion Tindakbalas Pelakuran

7. before = 2 x 2.01410 = 4.0282 after = 3.01603 + 1.00867 = 4.0247 Mass defect = 4.0282 – 4.0247 = 0.0035 E = 0.0035 x 1.6 x 10 -27 x (3 x 10 8 ) 2 = 5.229 x 10 -13 J

8. 3 A heavy nucleus is split into two lighter nucleus Nukleus berat dipisahkan kepada dua nukleus ringan Unstable nucleus Nukleus yang tidak stabil

9. E = mc 2 = 0.18606 x 1.66 x 10 -27 x (3 x 10 8 ) 2 = 2.78 x 10 -11 J
