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.
Answer:
c. More intense IR absorption occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.
Explanation:
When the molecules is exposed to the infrared radiation, the sample molecules absorb the radiation of wavelengths (specific to molecule) which causes change in the dipole moment of the sample molecules. The vibrational energy levels of the sample molecules consequently transfer from the ground state to the excited state.
Frequency of absorption peak is determined by vibrational energy gap.
Intensity of absorption peaks is related to change of dipole moment and possibility of transition of the energy levels.
Thus, by analyzing infrared spectrum,abundant structure information of the molecule can be known.
Hence, the correct answer to the question is
c. More intense IR absorption occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.
ON EARTH, every kilogram of mass weighs about 2.205 pounds.
So if you know the weight (in pounds), and you know that it was
weighed on Earth, you can simply divide the pounds by 2.205 ,
and you'll get the mass (in kilograms).
I can see that on this science homework, they used 2.2 for the weight
of 1 kilogram expressed in pounds. So just divide the weight by 2.2
to get the mass in kilograms.
(The weight number they gave you is not so random. :-) )
according to conservation of momentum , total sum of momentum of the objects taking part in a collision is same before and after the collision.
Total momentum before collision = Total momentum after the collision
when a cue ball moving at velocity 1.5 m/s hits a billiard ball , transfer of momentum takes place between the balls such that total sum of momentum of cue ball and billiard ball remain same before and after the collision.
hence we say that the momentum is conserved.
