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
Answer:
1.16 x 10⁻⁸N
Explanation:
Given parameters:
Mass of the two asteroids = 50000kg
Distance between the asteroids = 3800m
Unknown:
Gravitational force between the two asteroids = ?
Solution:
To solve this problem, we apply the newton's law of universal gravitation:
Fg =
G is the universal gravitation constant
r is the distance between them
So;
Fg = = 1.16 x 10⁻⁸N
the answer should be 20 seconds
