 By conservation of angular momentum

I1*ω1 = I2*ω2 -----> I1*ω1/I2 = 129*95/32 = 383 RPM <<<<<

383 rev/min * 2πrad/rev * 1min/60s = 383*2π/60 = 40.1 radians/s <<<

A cylindrical fishing reel has a mass of 0.7 kg and a radius of 5.24 cm. A friction clutch in the reel exerts a restraining torq
Korolek [52]

Answer:

Explanation:

moment of inertia of reel = 1/2 mr² , m is mass and r is radius of the reel

= .5 x .7 x .0524²

= 96.1 x 10⁻⁵

If force required be F

F  x .0524 - 1.88 is net torque acting on the reel

F  x .0524 - 1.88 = moment of inertia x angular acceleration.

F  x .0524 - 1.88 = 96.1 x 10⁻⁵ x 65.7

F  x .0524 - 1.88 = .063

F  x .0524  = .063 + 1.88

F = 37.08 N

Determine the internal resistance of the capacitor.
11Alexandr11 [23.1K]

Answer:

The equivalent series resistance of a capacitor is the internal resistance that appears in series with the capacitance of the device. Almost all capacitors exhibit this property at varying degrees depending on the construction, dielectric materials, quality, and reliability of the capacitor.
