Two particles are separated by 0.38 m and have charges of 1.25 10-9 C and 1.92 x 10-C. Use Coulomb's law to predict the force between the particles if
the distance is doubled. The equation for Coulomb's law is Fe = kq,92, and
the constant, k, equals 9.00 x 10°Nm2c2
A. 1,50 x 10-7N
B. -3.74 x 10-8 N
C. 3.74 x 10-8 N
D. -1,50 x 10-7N

Amale bird-of-paradise uses a dance to attract mates in which it flaps its tail feathers on the ground and jumps around a potential female mate. a different male bird-of-paradise does a similar dance but it jumps around the female in the opposite direction. the female bird is only attracted to one style of dance, in one direction. this is an example of speciation.
