fusion - How much energy is released per unit mass from depressurizing degenerate matter?


A neutron star remnant consists mostly of neutron degenerate matter. If you happened to suddenly have 1 kg of it in your lap without the pressure necessary to keep it degenerate, I suppose it would "undegenerate" and release alot of energy. How much energy and/or effect compared to, say, 1 kg of hydrogen fusing in the Sun or a bomb? And for the different kinds of degenerate matter such as electron degeneracy, proton degeneracy, quark degeneracy (and maybe more), what would the relative proportions of energy released from them being suddenly depressurized or becoming "undegenerate". How much more powerful would one be compared to another.

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
