Which of the following statements are true about light bulbs? Check ALL that apply. * Incandescent bulbs work by having electrons flow through a wire filament that has a resistance high enough to cause heat and light to be produced.
LED stands for light emitting diodes.
CFL bulbs last the longest of any of the three types of bulbs.
LED bulbs are the least efficient of any of the three types of bulbs.
CFL bulbs are the most dangerous when broken.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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

its a 5.5 n

glad that
