According to the article "Nuclear shapes" by Renee Lucas the nucleus's shape is mainly modified by vibrational and rotational features happening within the cell. According to the article if i read correctly "near closed shells spherical shapes prevail, while between closed shells the large number of valence nucleons in orbit with large particle angular momentum leads to nuclei with large deformations leading them to not only maintain its shape but also alloying it to work.
        
                    
             
        
        
        
The average speed of the whole travel is equal to <u>400 mph</u>.
Why?
From the statement, we know that whole travel is divided into three parts. For the first part (traveling from New York to Chicago), we have that it was 3.25 hours and the covered distance was half of the total distance (1400mi). For the second part, we have that it was 1 hour (layover time), and the covered no distance. For the third part (traveling from Chicago to Los Angeles), we have that it was 2.75 hours, and it took the other half of the total distance (1400mi).
We can calculate the average speed of the whol travel using the following formula:

Now, substituting and calculating, we have:


Hence, we have the average speed of the whole travel is equal to 400 mph.
Have a nice day!
 
        
             
        
        
        
KHDMDCM. 
Now go from Kilometer to Centimeter: 5. 
Move the decimal 5 places to the right: 67,500,000 centimeters.
Hope this helps :)
        
             
        
        
        
Kinetic energy is never negative, but potential energy can be.
Potential energy depends on height above some reference level,
and you can pick any level you want as the reference.  So, if the
object is below the reference level you pick, then its potential
energy relative to your reference level is negative.  
What that means is:  You have to lift it / do work on it / give it more 
energy than it has now ... in order to move it to the reference level. 
(That's exactly the situation with electrons bound to an atom.  Their
energy is considered negative, because we have to do work and
give them more energy to rip them away from the atom.)
_____________________________________
Regarding the other choices:
-- Kinetic energy is scalar ... Yes.  So is potential energy. 
-- Kinetic energy increases with height ... 
   No. It doesn't, but potential energy does.
-- Kinetic energy depends on position ...
   No. It doesn't, but potential energy does.
        
             
        
        
        
Answer:
6 m
Explanation:
velocity = wavelength x frequency
444 m/s = wavelength x 74 Hz
444 m/s / 74 Hz = wavelength
wavelength = 6m
