A point charge is released from rest in a region containing an electric field. The charge will start to move:

a. in a direction that makes its potential energy increase.
b. in a direction that makes its potential energy decrease.
c. along a path of constant potential energy.
d. Either A or B, depending on the sign of the point charge.

b. in a direction that makes its potential energy decrease.

Explanation:

A positive charge always moves in the direction of electric field whereas the negative always moves in the direction opposite to the electric field. In both cases the potential energy of the of the charges decreases.

Similar to objects under gravity always tend to decrease their potential energy,  charges also, tend in move in the direction so that their potential energy is minimum.

b. in a direction that makes its potential energy decrease.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

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
