An L−R−C series circuit has 91.5 Ω , and the amplitude of the voltage across the resistor is 36.0 V . What is the average power
sesenic [268]

Answer:

14.16 W

Explanation:

We have given impedance Z=91.5 ohm

Voltage across the resistor = 36 V

We have to find the power delivered by the source

We know that according to telegens theorem , the absorbed = power delivered

So the voltage across the resistor = 36 V

Current in the RLC circuit i=\frac{V}{Z}=\frac{36}{91.5}=0.3934A this current will be same in the whole circuit as it is a series RLC circuit

Now the power absorbed by the resistor P=i^2R=0.3934^2\times 91.5=14.16W

As the power absorbed = power delivered

So power delivered by the source =14.16 W

When very electronegative atoms, like oxygen, bond to atoms with lower electronegativity, like lithium, what's the result?
umka2103 [35]

(A) The oxygen atom becomes strongly negative.

Explanation:

When a very electronegative atom like oxygen bonds to an atom with a lower electronegativity, like lithium, the oxygen atom becomes strongly negative and the lithium becomes strongly positive.

The attraction between these oppositely charged ions results in the formation ionic bond.

  • An ionic bond is an interatomic bond in which a highly electronegative atom is bonded to less electronegative one.
  • The electronegative nature of the oxgyen allows is to gain the electrons lost by weakly electronegative lthium.
  • Most metals have low electronegativity.
  • They then both will form ions.
  • The attraction between the oppositely charged ions results in an ionic/electrovalent bonding.

Analysis: (use a separate sheet of paper)
Zolol [24]

Speed, frequency and wavelength are interconnected to each other.

<h3>What happens to the wavelength if the frequency increases?</h3>

As a wavelength increases in size, its frequency and energy (E) decrease. As the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

The wave speed is equal to the product of its frequency and wavelength, which shows the relationship between frequency and wavelength.

So we can conclude that speed, frequency and wavelength are interconnected to each other.
