Answer:

<u>Inductance,L:</u>

"The property of the conductor or the solenoid to generate the electromotive force,emf due to the flow of current,I."

<u>Unit:</u>  henry,H as it is equivalent to, kg.m².sec⁻².A⁻².

Explanation:

<u>Data:</u>

  • Voltage,v=120 v-rms,
  • Frequency,f=1000 Hz,
  • Capacitor, C=2.00 μF,
  • Current,I=0.680 A,

<u>Solution:</u>

We need to calculate the inductance, L of the solenoid inside a circuit,

  1. I=v/z,
  2. Z=√R²+(Lω-1/Cω)²,
  3. putting the values
  4. I=V/√R²+(Lω-1/Cω)²,
  5. 0.680=120/√(100)²+(L×2π×1000-1/2×10⁻⁶×2π×1000)²,
  6. L=35.8×10⁻³H, or<u> L=35.8 mH.⇒</u>Answer

Answer:

The inductance of the inductor is 35.8 mH

Explanation:

Given that,

Voltage = 120-V

Frequency = 1000 Hz

Capacitor C= 2.00\mu F

Current = 0.680 A

We need to calculate the inductance of the inductor

Using formula of current

I = \dfrac{V}{Z}

Z=\sqrt{R^2+(L\omega-\dfrac{1}{C\omega})^2}

Put the value of Z into the formula

I=\dfrac{V}{\sqrt{R^2+(L\omega-\dfrac{1}{C\omega})^2}}

Put the value into the formula

0.680=\dfrac{120}{\sqrt{(100)^2+(L\times2\pi\times1000-\dfrac{1}{2\times10^{-6}\times2\pi\times1000})^2}}

L=35.8\ mH

Hence, The inductance of the inductor is 35.8 mH

The 9-inch-long elephant nose fish in the Congo River generates a weak electric field around its body using an organ in its tail
Alik [6]

Answer:

1.34\cdot 10^{-16} C

Explanation:

The strength of the electric field produced by a charge Q is given by

E=k\frac{Q}{r^2}

where

Q is the charge

r is the distance from the charge

k is the Coulomb's constant

In this problem, the electric field that can be detected by the fish is

E=3.00 \mu N/C = 3.00\cdot 10^{-6}N/C

and the fish can detect the electric field at a distance of

r=63.5 cm = 0.635 m

Substituting these numbers into the equation and solving for Q, we find the amount of charge needed:

Q=\frac{Er^2}{k}=\frac{(3.00\cdot 10^{-6} N/C)(0.635 m)^2}{9\cdot 10^9 Nm^2 C^{-2}}=1.34\cdot 10^{-16} C

When you describe a liquid as thick, are you saying that it has a high or a low viscosity?
Umnica [9.8K]
It is commonly perceived as "thickness", or resistance to pouring. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity.
