El diálogo intercultural es un intercambio de opiniones abierto y respetuoso entre individuos y grupos pertenecientes a diferentes culturas que conduce a una comprensión más profunda de la percepción global del otro
Explanation:
“Intercultural dialogue is an open and respectful exchange of views between individuals and groups belonging to different cultures that leads to a deeper understanding of the other's global perception.”
Explanation:
Since, it is given that one hand completes 3.19 vibrations in 8.46 sec. Therefore, in one second the number of vibrations will be as follows.

= 0.377 vibrations
Hence, frequency (f) = 0.38 Hz
Now, formula to calculate the speed is as follows.
v = 
or,
= 
= 1.57 cm
Thus, we can conclude that the wavelength is 1.57 cm.
Answer:
vector of zero magnitude
Explanation:
The displacement is a vector magnitude, therefore, in addition to being a module, it has direction and sense.
In this case it moved 350 m and then returned the same 350 m, so the total displacement is zero.
If we draw the vector, one has a directional direction to the right and the other direction to the left, therefore when adding the two vectors gives a vector of zero magnitude
