A researcher wants to understand the relationship between horror movies and memory in teenagers. The researchers had teens ages 14 through 17 view various types of horror movies over the course of six hours (roughly 3 movies). Prior to viewing, the teens were given visual and auditory memory tasks. After viewing, they were readministered tests of visual and auditory memory. The researchers found that after six hours of viewing horror films, visual memory declined but auditory memory remained the same.

QUESTION 1 A gas is contained in a piston-cylinder arrangement and undergoes an isothermal expansion. Initially, the gas is at a pressure of 2 MPa and a volume of 0.05 m³. The gas expands isothermally at a temperature of 300 K until the volume doubles. 1.1 Determine the work done by the gas during the isothermal expansion. Assume the gas behaves as an ideal gas. (11) 1.2 Calculate the amount of heat transferred to the gas during this process. Use the first law of thermodynamics for an isothermal process to perform the energy balance. (6) 1.3 Verify the energy balance around the system using the first law of thermodynamics. (5) [22 MARKS]

/*Part G: getRegExString Create a method called getRegExString that prompts the user to input a String that matches a RegEx pattern. Make sure that you bulletproof the input by using the hasNext methods, reading the trash, and clearing the pipe after reading the value (the newline fix). - Pipe is a Scanner object that you created in main in the usual way i.e. in or console - Prompt is the message to display as the prompt for the input. - RegEx is the regex pattern in java String format to use for matching*/ //public static String getRegExString(Scanner pipe, String prompt, String regex)

2. Consider the following two periodic sequences: $x_1[n] = 1 + \sin\left(\frac{2\pi n}{10}\right)$ $x_2[n] = 1 + \sin\left(\frac{20\pi}{12}n + \frac{\pi}{2}\right)$ a. Determine the period of $x_1[n]$ and of $x_2[n]$. b. Determine the sequence of Fourier series coefficients $a_{1k}$ for $x_1[n]$ and $a_{2k}$ for $x_2[n]$. 3. Consider a sequence $x[n] = \sum_{k=-\infty}^{\infty} \delta[n - 4k]$ Sketch $x[n]$, and find the Fourier coefficients $a_k$ of $x[n]$.
