Answer:
First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.
Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.
Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Explanation:
Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:
- Longitudinal wave and
- Transverse wave.
In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:
- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.
- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Answer:
k = 0.292 N / m
Explanation:
The glider with the spring forms a system with a simple harmonic movement, in this type of movement the angular velocity is given by
w = √ k / m
The angular velocity is related to the frequency and is related to the period
w = 2π f
f = 1 / T
We replace
2π / T = ra (k / m
T = 2π √ (m / k)
The period is the time of a complete oscillation, in this case the glider starts from the equilibrium point and returns for the first time, this corresponds to the middle of the period
½ T = 2.60 s
T = 2 2.60
T= 5.20 s
We clear the equation
T² = 4π² m / k
k = 4π² m / T²
Let's calculate
k = 4π² 0.200 / 5.20²
k = 0.292 N / m
