Electroreception is limited to aquatic environments because on here is the resistivity of the medium is low enough for electric currents to be generated as the result of electric fields of biological origin. In air, the resistivity of the environment is so high that electric fields from biological sources do not generate a significant electric current. Electroreceptor are found in a number of species of fish, and in at least one species of mammal, the Duck-Billed platypus.

Magnitude: Magnitude generally refers to the quantity or distance.
Attraction: A force that makes things move together and stay together.
Repulsive: The feeling of being repelled, as by the thought or presence of something; distaste, repugnance, or aversion.
Current: Current is the rate of flow of electric charge. A potential difference (voltage) across an electrical component is needed to make a current flow through it.

Answer:
188.7 m
Explanation:
height of bridge above water (h) = 393 m
mass of bungee jumper (m) = 150 kg
length of cord (L) = 78 m
acceleration due to gravity (g) = 9.8 m/s
initial energy = mgh = 150 x 9.8 x 393 = 577,710 J
since the jumper barely touches the water, the maximum extension of the cord (x) = 393 - 78 = 315 m
from the conservation of energy mgh =
therefore
577,710 =
k = 11.64 N/m
from Hooke's law, force (f) = kx' ⇒ mg = kx'
where x' is the extension of the cord when it comes to rest
150 x 9.8 = 11.64 × x'
x' = 126.3 m
the final height at which the cord comes to a rest = height of the bridge - length of the cord - extension of the cord when it comes to rest
the final height at which the cord comes to a rest = 393 - 78 - 126.3 = 188.7 m
