To understand the relationships among the parameters that characterize a wave. It is of fundamental importance in many areas of
1 answer:
Answer:
The correct option is (c) "periodic wave"
Explanation:
The relationship between the angular frequency and the radial frequency is :
f is the radial frequency
Frequency, wavelength, velocity of propagation, and related variables do not depend on the amplitude of wave. Travelling waves are also known as periodic wave if their waveform repeats every time interval T. Frequency, wavelength and the speed of wave are the factors that defines traveling waves.
So, the correct option is (c) "periodic wave".

Answer:
The correct option is C: 0.31 s.
Explanation:
When the mass is then suddenly released we have:
Where:
F is the force
k: is the spring constant
Δy: is the spring displacement
Since the tension in the spring is zero, the force is the weight:
Where:
m is the mass of the object
g is the gravity
(1)
The oscillation period of the spring is given by:
(2)
By solving equation (1) for "k" and entering into equation (2) we have:
Since the spring will osclliates in a position between the initial position (when it is at rest) and the final position (when the mass is released and reaches the bottom), we have Δy = 2.5 cm = 0.025 m:
Hence, the oscillation period is 0.31 s.
The correct option is C: 0.31s.
I hope it helps you!
