An electric ell develops a 450V potential difference between its head and tail. The eel can stun a fish or other prey by using this potential difference to drive a 0.80 A current pulse for 1 ms. What is the energy delivered by this pulse and (b) what is the the total charge that flows?

Given Information:

Potential difference = V = 450 V

Current = I = 0.80 A

time = t = 1 ms = 0.001 s

Required Information:

(a) Energy = E = ?

(b) Total charge = q = ?

(a) Energy = 0.36 J

(b) Total charge = 8x10⁻⁴ C

Explanation:

(a) What is the energy delivered by this pulse

The energy is given by

E = V*I*t

Where V is the potential difference, I is the current flowing and t is the time.

E = 450*0.80*0.001

E = 0.36 J

(b) what is the the total charge that flows?

We know the current is the rate of charge

I = q/t

q = I*t

q = 0.8*0.001

q = 0.0008

q = 8x10⁻⁴ C

c. magnitude and direction

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
