Continents move slowly over time Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics. The continents are still moving today. :P
Answer:
100 cm
Explanation:
It is given that there are two loudspeakers that produces along x-axis.
The maximum intensity of the sound is at a distance of = 15 cm apart.
The sound intensity becomes zero when the separation between the speakers are increased and becomes 65 cm.
Therefore, the sound waves are in the phase,
The sound waves are out of phase when
Therefore,
= 2 (65 - 15)
= 2 x 50
= 100 cm
Hence the wavelength of the sound is 100 cm.
Its the first one with the circle and the arrows going around it
