Part A A sinusoidal electromagnetic wave is traveling in the $+z$ direction. It has a period of $2 \, \mu s$, and its magnetic-field magnitude is $1 \times 10^{-2} \, T$. Write down the equation for the magnitude of the wave's electric field vector $\vec{E}$. Express your answer in volts per meter in terms of $t$, $\pi$, and $z$. Express the coefficients using three signature figures. $|\vec{E}| = 3.00 \cdot 10^6 \sin \left( \frac{2\pi}{2 \cdot 10^{-6}} t - \frac{2\pi}{2 \cdot 10^{-6} \cdot 3.00 \cdot 10^{-6}} z \right)$

3. Functions (25%) Answers to the following questions should be implemented as functions in a program called functions.py. While coding, check Python libraries for methods that may make your job easier. a. Write a function that takes in a string as an argument, and returns a string where for every single char in the original string, there are two chars. For example double_char('The')) -> 'TThhee' and double_char('Hi-') ->HHii--. b. Write a function that takes a list and returns a new list with unique elements of the first list. For example, unique_list([1,2,3,3,3,4,4,5]) -> [1,2,3,4,5].
