An electric eel delivers a current of 0.65 A to a small pencil-thin prey 15 cm long.

A) If the eel's "bio-battery" was charged to 500 V , and it was constant for 20 ms before dropping to zero, estimate the resistance of the fish.

Express your answer using two significant figures.

B) Estimate the energy delivered to the fish.

Express your answer using two significant figures.

C) Estimate the average electric field (magnitude) in the fish's flesh.

Expert Solution

Resistance of wire is R = V /I

= 500 V / 0.65A

= 769.23 ?

Power P = VI

Then the energy E = P*time

= VIt

= 500V*0.65A*20x10^-3 s

= 6.5 J

Average electric field is ?E = V / L

= 500V / 0.15 m

= 3333.33 N/C

= 3.0 kN/C

A thin stick of length 80.0 cm and mass 120.0 g has two small spherical masses attached to its opposite ends (treat them as point masses). One mass is 20.0 g and the other mass is 50.0 g. The stick rotates frictionlessly about a horizontal axis passing through its centre. If the stick starts from rest in a horizontal position, what is the linear speed of the larger spherical mass at the moment that it is passing through its lowest...
