Find the linear speed the bicycle required to power its head light by a generator, whose rubber shaft presses against the wheel of cycle of radius .0.33 m, turns at an angular speed of 44 times as great as the angular speed of the tire itself. The coil consists of 75 turns, has an area of 2.6 × 10-3m2 and rotates in a 0.10 T magnetic field. When the peak emf being generated is 6.0 V.

Question

Find the linear speed the bicycle required to power its head light by a generator, whose rubber shaft presses against the wheel of cycle of radius .0.33 m, turns at an angular speed of 44 times as great as the angular speed of the tire itself. The coil consists of 75 turns, has an area of 2.6 × 10-3m2 and rotates in a 0.10 T magnetic field. When the peak emf being generated is 6.0 V. (A) 2,5 m/s (B) 5 m/s (C) 2,3 m/s (D) 4.6 m/s

ν = r ((1/44) ) ωcoil where ωcoil = (e.m.f/NAB)

2,5 m/s

5 m/s

2,3 m/s

4.6 m/s

ν=r(441​)ωcoil​ where ωcoil​=NABe.m.f​

$ν = r (\frac{1}{44}) ω_{co i l}$ where $ω_{co i l} = \frac{e . m . f}{N A B}$
