When a sound wave moves through a medium such as air, the motion of the molecules of the medium is in what direction (with respe
Alchen [17]

<span>A sound wave is a pressure wave that results from the vibration of the particles o the medium from the source. The motion of the particles in the medium is parallel to the direction of the energy transport. The type of wave formed by a sound wave is the longitudinal wave. </span>A longitudinal wave is characterized by rarefactions. A longitudinal wave is a wave motion wherein the particles in the wave medium are displaced parallel to transport. When motion is detected from the source, the particle next to it vibrates from its rest position and a progressive change in phase vibration is observed at each particle within that wave. The result is that the energy is transported from one region to the other. These combined motions result in the movement of alternating regions of rarefaction in the direction of propagation.

A 40.0-μFcapacitor is connected across a 60.0 Hz generator. An inductor is then connected in parallel with the capacitor. What i
amm1812

Answer:

The value of the inductance is 175.9 mH.

Explanation:

Given that,

Capacitor C= 40.0\ \muF

Frequency = 60.0 Hz

The inductor and capacitor is connected in parallel, the voltage across each of these elements is the same.

We have,

V_{L}=V_{C}

Using ohm's law

I_{rms}\times X_{L}=I_{rms}\times X_{C}

X_{L}=X_{C}

2\pi f L=\dfrac{1}{2\pi f C}

L=\dfrac{1}{4\pi^2\times f^2\times C}

Put the value into the formula

L=\dfrac{1}{4\times\pi^2\times60.0^2\times40\times10^{-6}}

L=0.1759\ H

L=175.9\times10^{-3}\ H

L=175.9\ mH

Hence, The value of the inductance is 175.9 mH.

How many miles can you get on one tank of gas if your tank holds 18 gallons and you get 22 miles per
MrRissso [65]
Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following:
18 gallons * 22 miles / 1 gallon
Which simplifies to 18 * 22 miles = 396 miles.
