In Euclidean geometry with standard inner product in R3, determine all vectors v that are orthogonal to u=(9,4,0). The Sun has a radius of 7. 105 kilometers. Calculate the surface area of the Sun in square meters. Note that you can approximate the Sun (symbol ) to be a sphere with a surface area of A = 4TR where Ro is the radius (the distance from the center to the edge) of the Sun. In this class, approximating = 3 is perfectly fine, so we can approximate the formula for surface area to be Ao 12R. x 10 square meters Hint: 1 km: 1 (km) = 1 kilo m = 1 (10) m = 100 m zheng js, tang s, qi yk, wang zp, liu l (2013) chemical synthesis of proteins using peptide hydrazides as thioester surrogates. nat protoc 8(12):24832495.
