Answer

Correct answer is amplitude

Explanation:

Frequency: frequency is the number of complete waves which passes through a point in one second. SI unit of frequency is Hertz (Hz). Frequency depends on Wavelength. Frequency is inversely proportional to wavelength. It means if wavelength of wave is higher, then its frequency will be shorter.

Wavelength: wavelength is the distance between adjacent crests. SI unit of wavelength is meters. Wavelength depends on frequency. Wavelength is inversely proportional to frequency, it means if frequency of wave is higher, then its wavelength will be shorter.

Speed : Speed of wave is defined as the speed with which a wave propagate in a medium or vacuum. SI unit of speed is m/s. Wave speed depends on wavelength and frequency by following equation

$speed=frequency\times wavelength$

Amplitude: Amplitude is the height of the wave. SI unit of amplitude is meter. Amplitude is independent of frequency, wavelength and speed. So it is correct answer

A square plate of copper with 55.0 cm sides has no net charge and is placed in a region of uniform electric field of 82.0 kN/C d

Alex73 [517]

Answer

given,

Side of copper plate, L = 55 cm

Electric field, E = 82 kN/C

a) Charge density,σ = ?

using expression of charge density

σ = E x ε₀

ε₀ is Permittivity of free space = 8.85 x 10⁻¹² C²/Nm²

now,

σ = 82 x 10³ x 8.85 x 10⁻¹²

σ = 725.7 x 10⁻⁹ C/m²

σ = 725.7 nC/m²

change density on the plates are 725.7 nC/m² and -725.7 nC/m²

b) Total change on each faces

Q = σ A

Q = 725.7 x 10⁻⁹ x 0.55²

Q = 219.52 nC

Hence, charges on the faces of the plate are 219.52 nC and -219.52 nC
