An explanation of sound<span> waves. The pitch of a </span>sound<span> is dictated by the frequency of the </span>sound<span> wave, while the loudness is dictated by the </span>amplitude<span>. When a drum is beaten, the air particles around the drum skin vibrate in the form of a compression wave</span>
Answer:
10m/s
Explanation:

Since there is no initial velocity as the object is dropped, you can write the following equation:

Now that you know how long the fall took, you can use another physics equation to find the velocity at that point.

Since there once again is no initial velocity, you can rewrite this as:

A tsunami wave is different than a normal wave because it is caused by an sudden displacement in the ocean. a earth quake below the ocean floor, a landslide, or a meteorite impact. normal waves are caused by the wind, weather and tides, unlike tsunamis. the long wavelengths from the impact from a earthquake can make the wave slow down and increase the amount of water + height for the wave, making a larger impact wave, a tsunami
