In thinking of an inductor as a circuit element, it is to consider its limiting behavior at high and low frequencies. at one extreme, the inductor might behave like a short circuit, that is, like a resistor with almost no resistance (an ideal wire) having essentially no voltage drop across it no matter what the current. alternatively, the inductor might behave like an open circuit, that is, like a resistor with large resistance so that essentially no current will flow no matter what the applied voltage. based on the formula you obtained for the reactance, how does an inductor behave at high and low frequencies?
a) like a short circuit at both high frequencies and low frequenciesb) like an open circuit at both high frequencies and low frequenciesc) like an open circuit at high frequencies and a short circuit at low frequenciesd) like an open circuit at low frequencies and a short circuit at high frequencies

Lyrics C :like an open circuit at high frequencies and a short circuit at low frequencies

Explanation:

The impedance produce by the presence of an inductance in an electric circuit  has a general equation  Z(r) = jωl  where  j is the imaginay number, l is the inductor in henrios and ω is the frecuency of the curent ( ω = 2πf , f is the frecuency in hertz)

So module of the inductance directly depends on  ω = 2πf   then when f the frecuency increase, the value of ωl, also increase and when the value of f decrease ωl will decrease. For very high value of ω the inductance can become very very high ( even up to an open circuit ) and the              opposite for very low values of frecuencies ωl could be very low (as to a short circuit

explanation:

boats, things on boats luggage are way more heavy then water.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
