Afish is 17.9 cm from the front surface of a fish bowl of radius 45 cm. where does the fish appear to be to someone in air viewing it from in front of the bowl? do not forget the proper sign.

Fish will appear at distance 14.9 cm from the surface of bowl

Explanation:

As we know that fish is floating inside the water in fish bowl while it is observed from outside in air

so we have

here we have

now we have

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
