so what do we want our website for the best of all I can get to see
Answer:
Gamma ray waves
Explanation:
Gamma ray waves carry the most energy electromagnetic waves.
Hope this helps, thank you !!
Answer:
Explanation:
Those kind of problems of electric physics is about capacitors, so the normal questions are:
What are the charge on each electrode?
Solve this you can get other information required in the problem or write down the other questions you need
Capacitance
The charge is find by the equation
The reactance of an inductor is given by:
X = 2πfL
X is the inductor's reactance
f is the frequency of the supplied voltage
L is the inductor's inductance
The given values are:
f = 60.0Hz
L = 43.8mH (I'm assuming the value is given in milli Henries because this is within the normal range of inductors)
Plug these values in and solve for X:
X = 2π(60.0)(43.8×10⁻³)
X = 16.512Ω
Round this value to 3 significant figures:
X = 16.5Ω
The relationship between AC voltage and current is given by:
V = IZ
V is the voltage
I is the current
Z is the impedance
For an AC inductor circuit, Z = X = 16.512Ω and V is the rms voltage 120V. Plug these values in to get the rms current:
120 = I×16.512
I = 7.2673A
Round this value to 3 significant figures:
I = 7.27A
Answer:
0
-723.163841808 Wb
-350.282485876 Wb
Explanation:
= Permittivity of free space =
when r = 0.625 m the charges lie outside the sphere so q = 0
From Gauss law
The electric flux is 0
when r = 1.4
will be inside the sphere
The electric flux is -723.163841808 Wb
when r = 2.9 both charges lie inside the sphere
The electric flux is -350.282485876 Wb
