Identify the following particles A, B, C as having a positive, negative or neutral charge. Which of the following statements is true? A. An object that is positively charged contains all
neutrons and no electrons.

B. An object that is negatively charged contains an equal
amount of protons and electrons.

C. Neutral objects contain equal amounts of positively
and negatively charged particles

D. All objects are neutral 99% of the time.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

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

c) up

hope this
