Answer:
q=6.22*10^-10C
Explanation:
Two large metal plates of area 0.88 m2 face each other, 4.8 cm apart, with equal charge magnitudes but opposite signs. The field magnitude E between them (neglect fringing) is 80 N/C. Find |q|
E=α/∈, electric field within the plate
α=q/A
A=area of the plate
∈=is the permittivity
substituting , we have
The field magnitude E between them (neglect fringing)
E=q/A∈
q=EA∈
q=0.88*80*8.84*10^-12
q=6.22*10^-10C
Answer:
1.364 m
Explanation:
We are given that
Frequency,f=110 MHz=
We have to find the distance between the nodal planes of the magnetic field.
We know that
Wavelength,
Where c=
Using the formula
Distance between nodal planes of the magnetic field
C. 0.37V. A capacitor of 650x10⁻⁴F that stores 24x10⁻³C has a potential difference of 0.37V between its plates.
The key to solve this problem is using the capacitance equation C = Q/Vᵃᵇ, where C is the capacitance, Q the charge stored in the plates, and Vᵃᵇ the potential difference between the plates.
A 650x10⁻⁴F capacitor stores 24x10⁻³C, clear Vᵃᵇ for the equation:
C = Q/Vᵃᵇ -----------> Vᵃᵇ = Q/C
Solving
Vᵃᵇ = 24x10⁻³C/650x10⁻⁴F = 0.37V
When blue and orange color are given, then : Blue color has shorter wavelength and more energy as compared to orange.
<h3>What is visible spectrum?</h3>
Visible spectrum is that portion of electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light and human eye responds to wavelengths from about 380 to about 750 nanometers
Visible light comes in all the colors of the rainbow where each color has its own special frequency and wavelength. When all the colors are together, they make "white" light that we see.
Blue light has shorter wavelength more energy whereas orange light has the longer wavelength and low energy.
