Answer:
True b and c
Explanation:
In an RLC circuit the impedance is
examine the different phrases..
a) False. The maximum impedance is the value of the resistance
b) True. Resonance occurs when
(wL)² + (1 / wC)² = 0
w² = 1 / LC
c) True. In resonance the impedance is the resistive part and the power is maximum
d) False. In resonance the inductive and capacitive part cancel each other out
e) False. The impedance is always greater outside of resonance, but at the resonance point they are equal

Answer:
As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster.
Explanation:
A white dwarf also known as degenerate dwarf is a star or an electron degenerate matter and is as massive as the Sun but only about as large in size as planet Earth.
The maximum mass of a white dwarf is about 1.4 times the mass of the Sun.
Also, as the mass of a white dwarf increases, the pressure must increase to resist gravity and to do this, the electrons must move faster.

let the focal length of the lens is f and the distance of image is v.
use lens makers formula to find the focal length of the lens
By substituting the values, we get
.... (1)
By using the lens equation
from equation (1)
v = -1.19 m
