Parallel 33. A 4-watt night light is plugged into a 120-volt
circuit and operates continuously for a 30-day
month.
a. How much current does it draw?
b. What is the resistance of its filament?
c. How much energy does it use in the month?
d. What is the cost of its operation for the
month at the utility rate of 10 cents per
Kilowatt-hour?

it doesn't. it was imagined up in the middle ages.

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
