Longitudinal wave hope this is right :))))))))))
Answer:
Here we go!
Explanation:
if an object is traveling in such a way that it covers the same distance for each interval of time it is traveling, then it is said to be traveling with uniform speed.

Answer:
b
Explanation:
b. Culture bc Americans tend to have a more individualist orientation (focusing more on personal goals), while many Asians tend to have a
collectivist orientation (focusing more on family and work goals).
Solids - particles are close together in a regular structure and vibrate about fixed positions
liquids - particles are close together but free to move past each other randomly
gases - particles are far apart and move randomly in all directions
The density of a substance changes when it changes state. Its mass does not change. This is because its particles do not disappear - they are just rearranged and occupy a different volume.
1 mol of photons contained a number of photons equal to Avogadro number:
The total energy of the mole of photons is
, so the energy of a single photon is the total energy divided by the number of photons:
The energy of a single photon is related to its frequency f:
where h is the Planck constant. From this formula, we find the frequency of the photons in the problem:
And from the frequency we can finally calculate the wavelength
, using the relationship between wavelength, frequency and speed of light (c) for photons:
