Write a method stutter that takes an arraylist of strings and an integer k as parameters and that replaces every string with k copies of that string. for example, if the list stores the values ["how", "are", "you? "] before the method is called and k is 4, it should store the values ["how", "how", "how", "how", "are", "are", "are", "are", "you? ", "you? ", "you? ", "you? "] after the method finishes executing. if k is 0 or negative, the list should be empty after the call.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
