An electric eel develops a potential difference of 470 V , driving a current of 0.85 A for a 1.0 ms pulse. A. Find the power of this pulse.
B. Find the total energy of this pulse.
C. Find the total charge that flows during the pulse.

(a) The power of this pulse is 399.5 W

(b) The total energy of this pulse is 0.3995 J

(c) The total charge that flows during the pulse is 8.5 x 10⁻⁴ C

Explanation:

Given;

potential difference developed by the eel, V = 470 V

current, I = 0.85 A

time, t = 1 ms = 1 x 10⁻³ s

(a) the power of this pulse.

P = IV

P = 0.85 x 470

P = 399.5 W

(b) the total energy of this pulse

E = Pt

E = 399.5 x 1 x 10⁻³

E = 0.3995 J

(c) the total charge that flows during the pulse

Q = it

Q = 0.85 x 1 x 10⁻³

Q = 8.5 x 10⁻⁴ C

the answer would be   dignified - apex

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
