For the reactor described in Example 12.12, computethe alpha activity of the 238U present in the fuel rod.Assume that the uranium has been enriched to 4%235U, which is typical for a commercial power reactorfuel rod.
Tessa Fuegmann Week 1- PHY 2010 (1/8, 1/10, 1/12) Part 1: force and motion The big picture is change (chemical vs. biological). Key concepts are force(cause) and acceleration(effect). A model is a simplified description of reality. A model is used to demonstrate outcomes of situations and reduce the complexity of problems. Simplifying a situation through modeling equals successful problem solving Chapter 1 Introduces fundamental concepts of motion and basic mathematics 1.1-motion Motion is the change of an objects position or orientation with time. The path along which an object moves is called an object’s trajectory. Four basic types of motion Straight-line motion Circular motion Rotational motion
