Very unsure on my answers for these 2 questions. i really have no idea what i'm doing. could someone explain? will give medal and maybe become a fan if someone would just me understand! ? 1. which of the following energy yields is likely to have come from a fission or fusion reaction? 1.0 × 10^2 kj/mol 2.5 × 10^2 kj/mol 1.2 × 10^3 kj/mol *this 1.4 × 10^11 kj/mol 2. in a nuclear reaction, a change in mass of 1.0 × 104 g occurs. what is the corresponding change in energy? use the formula e = mc2. 9.0 × 10^3 kj *my best 9.0 × 10^6 kj 9.0 × 10^9 kj 9.0 × 10^12 k

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

first one is the correct answer
