Answer:
when you switch off an electrical curcuit you tend to create a 'break' in the curcuit,preventing the electric current to flow around the curcuit,this can be caused by a simple switch or 'break'
Explanation:
Answer:a) λ = 4.862 10⁻⁷ m, b) λ = 4.341 10⁻⁷ m
Explanation:
The spectrum of hydrogen can be described by the expression
in the case of the initial state n = 2 this series is the Balmer series
a) Find the wavelength for n = 4
let's calculate
= 1,097 10⁷ ()
\frac{1}{ \lambda} = 1.097 10⁷ 0.1875 = 0.2056 10⁷
λ = 4.862 10⁻⁷ m
b) n = 5
\frac{1}{ \lambda} = 1,097 10⁷ ()
\frac{1}{ \lambda} = 1.097 10⁷ 0.21 = 0.23037 10⁷
λ = 4.341 10⁻⁷ m
Answer:
The amount of charge at the center is -132.7 nC
Solution:
As per the question:
Electric flux from one face of cube, 
Edge, a = 19cm
Since, a cube has six faces, thus total flux from all the 6 faces = 
Also, from Gauss' law:
