1 answer:
Overall displacement of the object = 30 m
Average velocity = 0.6 m/s
Instantaneous velocity = 0.2 m/s
The correct graph is graph C.
<h3>What is displacement?</h3>Displacement is the distance travelled by an object in a specified direction.
Displacement is a vector quantity.
The overall displacement of the object = 40 m - 10 m
Overall displacement of the object = 30 m
Average velocity = displacement/time
Average velocity = 30 m/ 50 s
Average velocity = 0.6 m/s
Instantaneous velocity at t = 10.0 s
Instantaneous velocity = (15 - 10)/10
Instantaneous velocity = 0.2 m/s
The correct graph is graph C.
In conclusion, velocity is the change in displacement with time..

Answer:
2a.) Wavelength = 1.8 m
2b.) F = 66.67 Hz
3a.) Find the attached file
3b.) Wavelength = 0.6 m
Explanation:
Given that the
Length L = 0.9m
Wavelength (λ) = 2L/n
Where n = number of harmonic
If n = 1, then
Wavelength (λ) = 2L = 2 × 0.9 = 1.8 m
b.)
If waves travel at a speed of 120m/s on this string, what is the frequency
associated with the longest wave (first harmonic)?
Given that V = 120 m/s
V = Fλ
But λ = 2L, therefore,
F = V/2L
F = 120/1.8
F = 66.67 Hz
3. b.) If there are two node, the position will be in 3rd position which is 3rd harmonic
Using the same formula,
Wavelength (λ) = 2L/n
Where n = 3
Wavelength (λ) = 2 × 0.9/3
Wavelength (λ) = 0.6 m
