Write the answer in scientific notation, using the wanted unit. (1.26 x 10^4 kg) + (2.5 x 10^6 g)

write the answer in kilograms.

1.51 x 10^4 kg

Explanation:

(1.26 x 10^4 kg) + (2.5 x 10^6 g)

= 12600 kg + 2500000 g

= 12600 kg + (2500000 g / 1000 )

= 12600 kg + 2500 kg

= 15100 kg

= 1.51 x 10^4 kg

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
