Sample "MChoi" type of questions: *Q88) Which of the following transformations is impossible in a closed and isolated system: Inside, Body N and Body P together have 120 J of KE and 200 J of potential energy. What could happen 1 hour later? (C) Bodies N and M have 20 J of KE (combined) and now 100 J of potential '

', and a third party Zeta gains 200 J of KE due to a sudden interaction, within our system. (D) Bodies N and M fly through a glob of self-sticky fluid; and The fluid gains a higher temperature as a result of N and M flying through this fluid. So here, Mech.Energy of N and M gets somewhat reduced. (E) Bodies N and M fly through a glob of self-sticky fluid; and the fluid gets a reduction in temperature after N and M have flown through the glob of fluid. The glob remains united and does not have any change in potential energy; and velocity of C.of.M. for glob remains constant. . (A) Bodies N and M have 30 J of KE (combined) and now 290 J of potential 'E'. (B) Bodies N and M have 299 J of KE (combined) and now 21 J of potential '
