An inductor is connected to an AC generator. As the generator's frequency is increased, the current in the inductor A. Increases
Luda [366]

Answer:

B) Decrease

Explanation:

Resistance offered due to inductor in any AC circuit is given as

X_L = \omega L

here we know that

\omega = angular frequency

\omega = 2\pi f

now by ohm's law we know that

i = \frac{V}{X}

here we have

i = \frac{V}{\omega L}

so current is inversely depends on the frequency of AC

so if frequency is increased then the current will decrease

A damped harmonic oscillator consists of a mass on a spring, with a small damping force that is proportional to the speed of the
exis [7]

Answer:

2.19 N/m

Explanation:

A damped harmonic oscillator is formed by a mass in the spring, and it does a harmonic simple movement. The period of it is the time that it does one cycle, and it can be calculated by:

T = 2π√(m/K)

Where T is the period, m is the mass (in kg), and K is the damping constant. So:

2.4 = 2π√(0.320/K)

√(0.320/K) = 2.4/2π

√(0.320/K) = 0.38197

(√(0.320/K))² = (0.38197)²

0.320/K = 0.1459

K = 2.19 N/m
