The answer & explanation for this question is given in the attachment below.
Explanation:
Displacement is the shortest distance between two points. Displacement is used to calculate vector quantities such a velocity, force, acceleration, etc.
Here, Maria drove to the store and then to work this means that her total displacement will be the minimum distance between her initial point and her work place.
Hence, the minimum distance between her initial point and her work place is her total displacement.
Answer:
a
x-component 
y-component 
b
Magnitude 
direction is 
Explanation:
From the question we are told that
The first vertical distance is 
The first horizontal distance is 
The second vertical distance is 
Generally the displacement is
x-component 
y-component 
Generally the helicopters displacement is mathematically evaluated as



The direction is the angle the displacement of the helicopter makes with the horizontal which is mathematically evaluated as
![\theta = tan ^{-1}[ \frac{48}{20}]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%20%5E%7B-1%7D%5B%20%5Cfrac%7B48%7D%7B20%7D%5D)
=> ![\theta = tan ^{-1}[ 2.4 ]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%20%5E%7B-1%7D%5B%202.4%20%5D)
=> 
The approximate speed of the sound wave traveling through the solid material is 1012m/s.
<h3>
Wavelength, Frequency and Speed</h3>
Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
From the wavelength, frequency and speed relation,
λ = v ÷ f
Where λ is wavelength, v is velocity/speed and f is frequency.
Given the data in the question;
- Frequency of sound wave f = 440Hz = 440s⁻¹
- Wavelength of the wave λ = 2.3m
To determine the approximate speed of the wave, we substitute our given values into the expression above.
λ = v ÷ f
2.3m = v ÷ 440s⁻¹
v = 2.3m × 440s⁻¹
v = 1012ms⁻¹
v = 1012m/s
Therefore, the approximate speed of the sound wave traveling through the solid material is 1012m/s.
