Stays 4. There are two lit light bulbs in a circuit. One bulb burns out but the other
lit. Which statement is correct?
a) The two bulbs are wired in series.
b) The two bulbs are wired in parallel.
c) This is an impossible circuit — if one bulb goes out, the other bulb must
also go out.

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

continuous conducting path for current, power supply

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
