Amaterial is nonmagnetic and gaseous and does not conduct heat or electricity. it will, however, react with other elements. it is most likely a noble gas metalloid nonmetal metal

The correct option is: Nonmetal

Explanation:

Non-metals are the chemical elements that are generally present in the gaseous state at room temperature and have low electrical and thermal conductivity. These elements are non-magnetic and tend to have low density, boiling point and melting point. Non-metals have high electronegativity and ionization energy and react by sharing or gaining electrons from the other elements.

Therefore, the given material is most likely a non-metal.

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
