Answer: Brittle
Explanation:
took the test and I chose Soft, Soft is the wrong answer don't choose it. The CORRECT ANSWER IS BRITTLE
 
        
             
        
        
        
1. Frequency: 
The energy given is the energy per mole of particles:

1 mole contains a number of Avogadro of particles,  , equal to
, equal to
 particles
 particles
So, by setting the following proportion, we can calculate the energy of a single photon:

This is the energy of a single photon; now we can calculate its frequency by using the formula:

where
 is the Planck's constant
 is the Planck's constant
f is the photon frequency
Solving for f, we find

2. Wavelength: 
The wavelength of the photon is given by the equation:

where 

is the speed of the photon (the speed of light). Substituting,

 
        
             
        
        
        
Answer: The motions shifts.
 
        
             
        
        
        
Velocity because it gives the displacement and time
