<span>When placing each domino upright, potential energy is conserved in that domino. When kinetic energy is initially added into the first domino, this energy converts the next domino's potential energy to kinetic energy, which is transferred to the next domino afterwards. Hope this helps ;3</span>
<span>Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. Therefore, the correct answer that would best complete the given statement above would be second option. </span>Weather changes occur primarily because of <span>heat exchange between the sun and atmosphere. Hope this helps.</span>

Answer:
The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz will be detected. ... These sounds will interfere to produce detectable beats.
