The speedometer of a car moving to the east reads 55 mph. it passes another car that moves to the west at 55 mph. the cars have the same a. velocity b. speed c. same speed and velocity d. neither the same speed nor the same velocity

-- The cars have the same speed.

-- The magnitudes of their velocities are equal.

-- Each car's velocity is the negative of the other's.

Pick choice-B.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

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