A student wrote the following statements about ocean waves. Statement 1: They have long wavelength. Statement 2: They are driven
Sergio039 [100]
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.

3. Explain why one side of the single magnet attracted the metal surface, but repelled the stack of magnets
valina [46]

Explained

A car initially at rest undergoes uniform acceleration for 6.32 seconds and covers a distance of 120 meters. What is the approxi
Alja [10]
The approximate acceleration of the car would be <span>3.00

</span>How? We have to use the formula to find the velocity.

v = d/t = 120/6.32

v = 19

Then plug the factor into the acceleration formula to find the acceleration:

a = v/t = 19/6.32

a = 3.00

So, the approximate acceleration of the car would be 3.00
