I am somewhat confused and having issues coming up with a good topic, with the independent and dependent variables (with levels) suggested/provided by the instructor for an experimental research study. I was thinking "How does music affect memory", however, I am not sure what is a proper topic that will go with the IV and DV suggested even though it is written down which makes me feel more clueless because I have to create/make an experiment with it. INSTRUCTOR: "I think we can keep it simple. Since you will not be able to manipulate exercise, (i.e., tell people not to exercise and tell others to exercise) why don't you just manipulate the music variable and see if music has an impact on memory. Therefore, you have control and are able to manipulate music as your independent variable. Below is how it could look. Independent variable: music (your preference as the two levels, but it could be music/no music). Dependent variable: how many items participants remembered (you can create something for this).

If $A = \begin{pmatrix} 1 & 0 \\ 2 & 2 \\ -1 & -1 \end{pmatrix}$ and $B = \begin{pmatrix} 1 & 2 & 1 \\ 2 & -1 & 0 \end{pmatrix}$, then find the $(1,1)$ entry of $AB$.

QUESTION 4 Use the Matlab command lsim to solve the differential equation shown below. \(3 \frac{d^2x(t)}{dt^2} + 2x(t) = t + \sin(3t)\) \(x(0) = 0\) and \(\dot{x}(0) = 0\). Using the time step of 0.01 seconds, what is \(x(t=0.87)\)? Keep 4 digits after the decimal point (e.g. 0.1234). Do not use scientific notation. NOTE: The system can be defined using either tf or zpk. If tf or zpk is used, the initial conditions must be zeros. If the initial conditions are not zeros, and you still want to use lsim, then the system must be defined using state-space model (ss.m).

Name: Conclusion Questions: Circle the correct answer. 1. An endothermic reaction is a reaction that releases/absorbs heat. (choose) 2. An exothermic reaction is a reaction that releases/absorbs heat. 3. Temperature directly affects enthalpy/entropy/both entropy and enthalpy of a system. 4. Thermodynamics favors increases/decreases in enthalpy. 5. Thermodynamics favors increases/decreases in entropy. 6. Thermodynamics favors increases/decreases in free energy. Hydrogen Peroxide Decomposition: Circle the correct answer. 7. Did a reaction occur without input of energy? Yes/No. 8. This tells us the sign of AG is +/-. 9. Based on the balanced chemical reaction, entropy appears to increase/decrease. 10. This tells us the sign of AS is +/-. 11. The sign of T (Kelvin) is always +/-. 12. The temperature change of the flask tells us the reaction was endothermic/exothermic. 13. Based on the temperature change and #12, AH for this reaction must be +/-. Ammonia Production Reaction: Circle the correct answer. 14. Did a reaction occur without input of energy? Yes/No. 15. This tells us the sign of AG is +/-. 16. Based on the balanced chemical reaction, entropy appears to increase/decrease. 17. This tells us the sign of AS is +/-. 18. The sign of T (Kelvin) is always +/-. 19. The temperature change of the flask tells us the reaction was endothermic/exothermic. 20. Based on the temperature change and #19, AH for this reaction must be +/-.
