The resonant frequency of a circuit is the frequency 
at which the equivalent impedance of a circuit is purely real (the imaginary part is null).
Mathematically this frequency is described as
Where
L = Inductance
C = Capacitance
Our values are given as
Replacing we have,
From this relationship we can also appreciate that the resonance frequency infers the maximum related transfer in the system and that therefore given an input a maximum output is obtained.
For this particular case, the smaller the capacitance and inductance values, the higher the frequency obtained is likely to be.

A system where matter and energy can not enter or leave the system
<span>sound waves are a type of wave sometimes called compression waves, vibrations with enough of an amplitude can compress and decompress the air adjacent to the object causing the waves to form.</span>
Answer:
The answer to your question is: c
Explanation:
a) The car stops moving. The statement is true because fromthe interval 5 to 10 s, the car does not move.
b) The car changes direction. This statement is true because from 0 to 5 seconds, the vehicle is moving away from the origin and from 10 to 12.5 is getting closer to the origin.
c) The speed of the car is constant during the trip. This sentence is wrong because from 0 to 5 is moving with one velocity and from 10 to 12.5 is moving with a different velocity.
d) The car returns to the starting point of the trip. This sentence is correct, the movement starts at displacement equals to zero and ends at the same displacement.
