Calculate the energy (in MeV) released in the decay of 239Pu. (Assume 1 u = 931.5 MeV/c2.) MeV (b) What fraction of the mass of a single 239Pu is destroyed in the decay? The mass of 235U is 235.043924 u.

In physics the desire of an object to keep doing what it is doing is termed?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

Aspacecraft that renters the earth’s atmosphere drastically slows down. the amount of kinetic energy the spacecraft has as it reenters the earths atmosphere
