The slope of the line is 
(change in ' y ' between the ends)  /  (change in ' x ' between the ends)
Slope = (630g - 0) / (70 cm^3 - 0)
Slope = (630 / 70) g/cm^3
<em>Slope =  9.0 g/cm^3</em>

It is the branch of science, in which we study different phenomena of atmosphere including climate and weather.
        
                    
             
        
        
        
Potential energy<span> is the </span>energy<span> that is stored in an object due to its position relative to some zero position. It is calculated by the expression PE = mgh where mg is the weight of the book and h is the height. It is calculated as follows:
PE = 50(1) = 50 J
</span>PE = 50(1.5) = 75 J
PE = 50(2) = 100 J
        
             
        
        
        
The wavelength 

 of the wave is 160 m, and this is the distance between two consecutive crests. The boat is located at a crest of the wave, this means that the first trough is located 80 meters from the boat (because the distance between a crest and a trough is half the wavelength).
The speed of the wave is 

so the time the boat takes to reach the first trough is
