Three metal spheres are placed next to each other as shown in the picture. a has two times the mass of b. c has one-third the mass of a. the distance between a and c is half that between a and b. given these conditions, which statement is true? a) the gravitational force between a and b is one-third that between a and c. b) the gravitational force between a and b is two-thirds that between a and c. c) the gravitational force between a and b is three-eighths that between a and c. d) the gravitational force between a and b is four- sevenths that between a and c.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
