Explanation Reason for correct answer: Option (b) is given as, “less energy, because of greater mass per nucleon” If uranium splits in two, The atomic number of two atoms would be 92 / 2 = 46 , that is, palladium. If it splits in ninety, 92 = 1 × 90 + 2 , we get ninety hydrogens and helium. So, there would be less energy from a ninety split instead of two because of greater mass per nucleon. Reason for incorrect answer: Option (a) is given as, “less energy, because of less mass per nucleon” The nuclear fission of uranium into two parts will release more energy than that of ninety pieces due to less mass per nucleons

Nuclear Reactions

Nuclear reactions are processes in which the fundamental characteristics of a nucleus changes. They change into a completely different nucleus. These processes occur naturally in an unstable nucleus. Bombarding an energetic particle can induce nuclear re…

Students have asked these similar questions

In (Figure 1) C1 = 6.00 μF, C2 = 6.00 μF, C3 = 12.0 μF, and C4 = 3.00 μF. The capacitor network is connected to an applied potential difference Vab. After the charges on the capacitors have reached their final values, the voltage across C3 is 40.0 V. What is the voltage across C4? What is the voltage Vab applied to the network? Please explain everything in steps.

I need help with these questions again. A step by step working out with diagrams that explains more clearly

In a certain region of space the electric potential is given by V=+Ax2y−Bxy2, where A = 5.00 V/m3 and B = 8.00 V/m3. Calculate the direction angle of the electric field at the point in the region that has cordinates x = 2.50 m, y = 0.400 m, and z = 0. Please explain. The answer is not 60, 120, or 30.
