A. A proton (q = 1.6 * 10 ^ - 19 * C) moves 4.0 * 10 ^ - 4 in the direction of an electric field that has a magnitude of 5.0 N/C b. What the change in the electrical potential energy associated with the proton ?

c. What is the potential difference between the proton's starting point and ending point?

ice to water 1 water to vapour 2 latent heat

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

pretty sure it's false

the answer is 12 as i may remember
