The best transition between the four options presented to represent a time when water molecules are moving closer together would be A. Frost forms on a window pane.
The closest distance that the water molecules can do is when the water is in the state of being solid. It is known that the solid state of matter has the closest distance from molecule to molecule that when a molecule tries to move, the others move as well creating a vibration and thus producing heat in the process. When they are in a liquid state, they are quite far from each other. In a gas state, they really are far from each. This explains the difference in their characteristics.
        
                    
             
        
        
        
Answer:b
Explanation:
Object will be stable if its center of gravity lies over its base of support.
If the center of gravity is above the center of buoyancy then it provides positive righting moment and the object floats over the liquid and such object is said to possess positive meta-centric height.
 
        
                    
             
        
        
        
Explanation:
Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.
The frequency and the wavelength has an inverse relationship.
For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.
The frequency range of visible region is from 400 nm to 700 nm.
