What does this repres

theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. the solution becomes completely blue after eight minutes.

what does this represent about the type of change happening in the container?
ent about the type of change happening in the container?

Explanation:

What Theresa saw is a chemical reactions due to the interaction between the two colors. There are several actions that constitutes evidence of chemical reactions: change in color, formation of bubbles, formation of smoke, the formation of a precipitate and a clear liquid becoming cloudy, all these effects are signs of a chemical reaction.

In this case, Theresa created an experiment where two substances are changing color from red to blue, this is a sing of a chemical reaction, that's the answer.

grav potential energy

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
