Can someone help me with the following matlab question? Use the techniques we've learned involving phaseplane to plot a phase portrait of dx⁄dt = 2
dy⁄dt = -3, where the x and y values are between -5 and 5. Then, on the same plot, use drawphase to draw at least three different solution curves. Include the resulting plot in your Word document.
Now, try changing the values of x′ and y′ from 2 and -3 to other constant values. Describe in your Word document how this changes the phase portrait.

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?
