Is a higher moment of inertia better?
Is a higher moment of inertia better? Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary.

How does the nucleus change in beta decay?
How does the nucleus change in beta decay? A beta results in a neutron emitting a high energy electron and becoming a positive proton. Beta decay changes the atomic number of the nucleus by increasing the number of protons, by decreasing the number of neutrons while leaving the atomic mass essentially the same. What does […]
