A20.0-µf capacitor is charged by a 150.0-v power supply, then disconnected from the power and connected in series with a 0.280 mh inductor. calculate (a) the oscillation frequency of the circuit; (b) the energy stored in the capacitor at time t = 0 (the time of connection to the inductor); (c) the maximum magnitude of current in the inductor.

Answer

given,

Capacitance of capacitor = 20.0-µF

Voltage =  150.0-V

inductance = 0.280 m H

a) the oscillation frequency of circuit

f = 2126.9 Hz

b)

         U = 0.225 J

c)Current in the inductor

instantaneous rate of change of current is equal to 535714 A/s

1 the 4 is sig

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
