Tom notes that the the bulb has an effective resistance of 5.0 Ω, that the voltmeter reads 2.0 V and that the ammeter reads 3.5 A. a) State Kirchoff's First Circuit Law. What implications does it have for the charge entering and leaving a circuit junction? [2] b) State Kirchoff's Second Circuit Law. [1] c) Calculate R1. [1] d) Calculate R2. [3] e) Calculate the power dissipated by the bulb. [1]

gravity

explanation:

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
