Document Summary

I ethics: ethics is a very important branch of philosophy concerned with a number of moral questions. Which actions are morally right and which are morally wrong? www. notesolution. com. 2: there are two main approaches to ethics: (1) theoretical ethics and (2) applied ethics. (1) theoretical ethics: examining the theories, models, and concepts that should guide ethical inquiry. This involves trying to construct a theoretical framework to assess the moral justification of actions. Theoretical ethics is thus, by definition, a normative enterprise. What norms, rules, or principles should govern the moral propriety of actions? www. notesolution. com. 3 (2) applied ethics: assessing, by way of one or more theoretical frameworks, the moral propriety of particular actions, behaviour, or policies. We use our theoretical framework to help us determine which actions are moral justified. Assuming the correctness of certain moral principles or rules, we need to apply these principles or rules to decide what kinds of actions and policies are ethically justified. www. notesolution. com.

From the theory section of the lab we have two ways to determinethe period of oscillations of
the mass m: ? = 2p/T and ?=
a. (5 points) Both ways to determine ? must give the same value.Equate the above equations and solve for T^2 .The result in part(a) should look like the standard equation for a straight line y =mx + b if the variable for the x-axis is taken to be the mass m (doa little rearranging if needed). This means if we plot T^2 vs. m wewould see a straight line.
b. ( 5 points) Compare the standard form of the equation for astraight line and the result for part (a) and determine thetheoretical value for the slope in terms of constants and thedynamical spring constant . In terms of the slope (and otherconstants), what is the value of the dynamical spring constant?
c. (5 points) Again, compare the standard form of the equation fora straight line and the result for part (a), what should thetheoretical value for the y-intercept be in terms of constants andthe dynamical spring constant and the effective mass of the spring?In terms of the y-intercept (and other known values), what is thevalue of the effective mass of the spring ?
