Write code and solve in Matlab

Perhaps the most famous equation in physics is $E=m{c}^2$ which relates energy $E$ to mass $m.$ The speed of light in a vacuum, $c,$ is the property that links the two together. The speed of light in a vacuum is $2\mathrm{.}9979{10}^8\frac{m}{s}.$

a$)$ Create a function called energy to find the energy corresponding to a given mass in kilograms. Your result will be in joules, since $1kg\frac{m^2}{s^2}=1J$

b$)$ Use your function to find the energy corresponding to masses from $1kg$ to ${10}^{6}kg.$ Use the logspace function $($consult help logspace$)$ to create an appropriate mass vector.

c$)$ Create a plot of your results using circles for the data points. Make $4$ subplots $(2$ rows, $2$ columns$)$ using different logarithmic plotting approaches $($e$.$g$.$ plot, semilogy, semilogx and loglog$)$ to determine the best way to graph your results.
