Two particles are separated by 0.38 m and have charges of -6.25 x 10-9C and 2.91 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
F kanga, and the constant, k, equals 9.00 x 109 Nm2/C2.

B. 2.83 x 10-7 N
C. -1.13 x 10-6N
O D. 1.13 x 10-6N

Arafura file snakes are large, aquatic, non-venomous snakes found in the flood-plains of australian rivers. they feed only on fish found in the rivers. it has been observed that heavy rainfall in the wet season in one year leads to prolonged inundation of the floodplains lasting a year or longer. it has also been observed that these snakes remain in good physical condition after a flood. explain how the file snake population in a region is likely to be affected by the prolonged inundation of a flood-plain.
