Part 1:
Below are basic arguments in English. Choose one argument and translate the argument into the symbolism of predicate logic. Use one of the proof techniques from Chapter 8 to demonstrate the validity of the argument.
1. Every fetus has an immortal soul. A thing has an immortal soul only if it has a right to life. Hence, every fetus has a right to life. (Fx = x is a fetus, Sx = x has an immortal soul, Rx = x has a right to life).
2. Some wars are just. No war of aggression is just. Therefore, there are wars that are not wars of aggression. (Wx = x is a war, Jx = x is just, Ax = x is a war of aggression).
3. At least one instance of intentional killing is not wrong. But every murder is wrong. Hence, some instances of intentional killing are not murder. (Kx = x is an instance of intentional killing, Wx = x is wrong, Mx = x is murder)
4. Only things that have human bodies are human. No soul has a human body. Only souls survive the death of the body. Therefore, no humans survive the death of the body. (Bx = x has a human body, Hx = x is human, Sx = x is a soul, Dx = x survives the death of the body)
Part 2:
Now, construct an alternate proof. In other words, if the proof was done using RAA, now use CP; if you used CP, now use RAA. Consider the following questions, as well, in your journal response: • Will a direct proof work for any of these? • Can the proof be performed more efficiently by using different equivalence rules?

The interaction of one photon with another can be
understood
by assuming that each photon can temporarily become a
“virtual”
electron-positron pair in free space, and the respective
pairs can then interact electromagnetically. (a) How long
does
the uncertainty principle allow a virtual electron-positron
pair
to exist if h 2mc2, where m is the electron mass? (b) If
h 2mc2, can you use the notion of virtual
electron-positron
pairs to explain the role of a nucleus in the production of
an
actual pair, apart from its function in ensuring the
conservation
of both energy and momentum?

A fourth grader decides she is going to make an electromagnet for her science fair project. She uses an iron nail, 50.cm of #22 copper wire and one D cell battery. The battery soon becomes so hot it burns her hand. She asks you why? You explain it is due to the internal resistance of the battery.
Objectives:
To design an experiment (do not test the plan) to measure the internal resistance of the battery in the fourth grader's electromagnet.
To plan and communicate an original experimental design.
To demonstrate a working knowledge of measurement techniques, ohm's law and energy dissipation in a DC circuit.
Materials:
None required
Investigate
Read through the entire lesson first. You are not to preform any hands-on experimentation in this assignment.
Design an original experiment that will measure the internal resistance of a D cell battery in the situation described.
Place a detailed description of your experimental design in the class Lab Data Wiki. Make sure you include:
A purpose
A detailed procedure
An equipment list
A safety statement
What data you will collect
What graphs/equations you will employ
What calculations you will make to achieve the stated purpose

Construct a closed PV-cycle for a gas of N= 12^22 particles, so that the final point is equal to the initial point. For each step and assuming that this is an ideal gas (so PV=NkT) and also that there is no loss of heat due to inefficiency, a) calculate/estimate the total work done BY the system (not ON the system) for each step (if your step isn't 'straight', you'll have to approximate the area under the curve), b) for each step, use the ideal gas law to estimate the temperatures at the endpoints of each step, and therefore the change in internal energy U, c) combining b) with a), estimate the heat added or withdrawn from the system for each step.
