Calculate the standard uncertainty for the Young's modulus,

in units kN/m2

i would think it's food chain

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
