1.    Consider two Stars A and B with temperatures TA and TB and radii RA and RB respectively. If TA = 2 TB and RA = ½ RB, which statement about the stars' luminosities, LA and LB, is true? using this formula: L= (R^2)(T^4)

a)    LA =LB

b)   LA = 2 LB

c)    LA = 4 LB

d)   LA = ½ LB

e)    LA = ¼ LB
