The distance between the center of a condensation and the center of an adjacent
rarefaction is 70.10 cm. if the frequency is 307.0 hz, how fast are these waves moving?

 v = 215.207 m/s

Explanation:

given,

distance between center of condensation and the center of adjacent refraction (λ) = 70.10 cm = 0.7010 m  (∵ 1 cm = 0.01 m))

frequency  = 307.0 Hz

to calculate how fast the wave is moving

      V = ν λ

      v = 307.0 × 0.7010

     v = 215.207 m/s

hence, the wave is moving with velocity of  v = 215.207 m/s

there's multiple reasons why the conquistadors were so successful in colonizing central america, and some of them are:

- they were seen as gods;

at the beginning, the spanish settlers were seen by the natives as gods, and this was mainly due to their white skin, and the way they came with their boats.

- possessed superior weaponry;

the spanish had gunpowder and guns, as well as cannons, while the natives did not had any fire weapons.

- made cleaver alliances;

they used the situation of tribes hating each other, so they made alliances with some of them which served them very well.

- brought diseases;

the native people were not immune to certain diseases the europeans brought with them, so they were dying from seeming harmless things for european standards.
