Charge on electron is 1.6x10^-19 Coulombs.In uniform circular motion v = r omega. omega = v/r. omega= 61/3.8 radians per second - cycle is 2pi radians. (61/3.8)x2pi cycles per second. A charge circulation rate of  (61/3.8)x2pix1.6x10^-19 Coulombs/second, or Amps. Which is a pretty small value of a current. Usually there many more electrons moving much faster, I think.

A closely wound rectangular coil of 75.0 turns has dimensions of 22.0 cm by 45.0 cm . The plane of the coil is rotated from a po
pentagon [3]

Answer:51.52 V

Explanation:

Given

N=75 turns

Area=22\times 45 cm^2

\theta =36^{\circ}

Emf induced =-N\frac{\mathrm{d}\phi }{\mathrm{d} t}

Emf=-75A\frac{B_2-B_1}{t}

Emf=-75\times 22\times 45\times 10^{-4}\frac{1(1-cos(90-36))}{6\times 10^{-2}}

Emf=51.52 V

Vision is blurred if the head is vibrated at 29 Hz because the vibrations are resonant with the natural frequency of the eyeball
Sidana [21]

Answer:

255.4 N/m

Explanation:

We can consider the system eyeball-attached to the musculature as a mass-spring system in simple harmonic motion, whose frequency of oscillation is given by

f=\frac{1}{2\pi}\sqrt{\frac{k}{m}}

where in this case, we know:

f = 29 Hz is the frequency of oscillation

k is the spring constant, which is unknown

m = 7.7 g = 0.0077 kg is the mass of the eyeball

Solving the equation for k, we find the spring constant of the musculature attached to the eyeball:

k=(2\pi f)^2 m=(2 \pi (29 Hz))^2 (0.0077 kg)=255.4 N/m
