The <span>flow of how a cold pack works on a sprained ankle is based on the second law of thermodynamics which states that energy will flow from a higher to a lower temperature. So your body heat will flow to the cold pack in which you will feel the coldness of the pack.</span>

Green: nm 495–570. Yellow: nm 570–590. 590–620 nm for orange. Red: 620-750 nm (400–484 THz frequency)
Solids' molecules are strongly attracted to one another. As a result, the molecules are barely moving and tightly packed. Because of this, shape and volume are fixed.
The forces of attraction and repulsion in liquids are comparable. Compared to the solid state, they move a little bit more. They then assume the shape of the container while still having a fixed capacity.
The attraction forces between the molecules in gases are quite weak. They move quite freely and grow in an effort to fill as much space as they can. Consequently, their volume and shape vary (adopt the shape of the container).

If all the energy she put into bending the bow is completely 
transmitted to the arrow, then the arrow has the 100 joules 
of kinetic energy when it leaves the bow.
                 Kinetic energy = (1/2) (mass) (speed)²
                         100 J        = (1/2) (0.5 kg) (speed²)
Divide each side by 0.25 kg:    100 J / 0.25 kg = speed²
 [ joule ] = [ newton-meter ] = kg-m²/sec²
                                                100 kg-m²/sec² / 0.25 kg = speed²
                                                 400 m²/sec² = speed²
Take the square root of each side:     speed = √400 m/s
                                                                                20 m/s 
                                                                    (about 44.7 mph)                                            
        
             
        
        
        
Answer:
C
Explanation:
Formula E=F/C also E=V/d
In this case use the second formula; E=V/d
Data given; E=4N/C d=8m
So v=E X d
      V=4x8=32V
k.e=eV= 2X32=64eV
