Angular speed is omega in radians/sec.
tangential speed = radius time omega
so take the tan speed and divide by the radius

A simple series circuit consists of a 120 Ω resistor, a 21.0 V battery, a switch, and a 3.50 pF parallel-plate capacitor (initia
slega [8]

Answer

Integral EdA = Q/εo =C*Vc(t)/εo = 3.5e-12*21/εo = 4.74 V∙m <----- A)

Vc(t) = 21(1-e^-t/RC) because an uncharged capacitor is modeled as a short.

ic(t) = (21/120)e^-t/RC -----> ic(0) = 21/120 = 0.175A <----- B)

Q(0.5ns) = CVc(0.5ns) = 2e-12*21*(1-e^-t/RC) = 30.7pC

30.7pC/εo = 3.47 V∙m <----- C)

ic(0.5ns) = 29.7ma <----- D)

Can you help me? Thanks! 10+ points!
Elis [28]

Explanation:

velocity: average velocity equals Displacement /change in time.

Kinetic energy: K=1/2mv^2 (m = Mass) ( v = Velocity).

speed using the kinetic energy is also KE =1/2mv^2

(M in Kg) (V in m/s)
