Black and Whites were hungry and thirsty
Answer:
(a) 83.06Ω
(b) 0.81A
(c) 25.0W
Explanation:
Comparing Δv = 95 sin 275t with Δv = Vmaxsinωt
ω = 275
Inductive reactance Χ = ωL
= 275 × 0.240
= 66 Ω
Capacitive reactance Χ = 1/ωc
= 1/ (275 × 26 x 10^-6)
= 139.86Ω
Impedance Z =
=
=
= 83.06Ω
(b)
solving for ,
substituting the value of and Z into equation, we have;
(c) Average power P = cos∅
To get the average power, we first solve for ∅ since it was not given.
∅
∅
∅
∅
∅ = -62.77°
Average power P = 0.81 × 67.2 × cos-62.77
P = 0.81 × 67.2 × 0.46
P = 25.03872W
P = 25.0W
Answer:
Part a)
Part b)
Explanation:
Part a)
Equilibrium distance is the distance between two centers when two ions just touch each other
So here we will have
Now Force of attraction between two ions is given by Coulomb's law
Part b)
At equilibrium separation net force between two ions must be zero
so the attraction force and repulsion force must be of equal magnitude
so we have
