Answer:
Speed of light in the glass
Explanation:
In this question we have given
angle of polaization,p=
we have to find the speed of light in the glass,v=?
We know that, refractive index of glass can be determined by following formula
................(1)
here,
c- speed of light in air
v-speed of light in glass
we also know according to brewester's law refrective index of glass is given as
n=tanp......................(2)
here p-angle of polarization
From equation (1) and equation (2)
we got
put value of c= and p= in equation 3
we got
<span>the dependent variable
<span>a variable (often denoted by y ) whose value depends on that of another.</span>

Answer:
B) an explanation for observable phenomena.
Explanation:
All theories have been stated by experiments and natural phenomenas.
Answer:
At resonance impedance of series RLC circuit is minimum and equal to resistance of the circuit
Explanation:
Let the resistance of the series RLC circuit is R
Capacitive reactance of the circuit is and inductive reactance of the circuit is
We know that impedance of the series RLC circuit is given by , here R is the resistance is inductive reactance and is capacitive reactance
At resonance capacitive reactance will be equal to inductive reactance
So
So impedance will become
So from above calculation we can say that impedance of series RLC circuit is minimum and equal to resistance of the circuit
