The statements which best describe the properties of tsunami waves are these: 1. THEY HAVE LONG WAVELENGTH.
2. THEY TRAVEL AT VERY HIGH SPEED.
Tsunami typically occur as a result of sudden displacement of gigantic water masses which erupted due to earthquake that occur on the sea bed. One peculiar characteristic of tsunami is the very wide distances between its wavelengths. A tsunami is a very long wavelength waves of water, its wavelength is much more greater than that of ordinary wave and can be as much as 300 kilometer.
Wavelength is refers to the distance between two identical points on a wave, that is, between wave crests or wave troughs.
Tsunami also travels at very high speed; it can travel for a long period of time at high speed without losing much energy.
<span>Answer:
Force is a vector. If you have one force pointed northeast and another northwest the east/west component would cancel each other out. The arithmatic sum of their magnitudes is the whole force.
If you have equal forces, one going north and one south, the net force would be 0 no matter how large the arithmetic sum might be.</span>
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
