John and jacob set out together on bicycle traveling at 15 and 12 miles per hour, respectively. after 40 minutes, john stops to fix a flat tire. if it takes john one hour to fix the flat tire and jacob continues to ride during this time, how many hours will it take john to catch up to jacob assuming he resumes his ride at 15 miles per hour? (consider john's deceleration/acceleration before/after the flat to be negligible)a. 3 b. 3 1/3c. 3 1/2 d. 4 e. 4 1/2

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
