The best answer is b - span.
A span is the distance between two bridge supports The supports may be towers, columns, or even the wall of a canyon.
There are many kinds of bridges  but they all fall into three types namely beam, arch and suspension. The major difference between these three kinds of bridges is the distance that each can cross in  a single span.
For example, a modern beam bridge is likely to span a distance of 200 feet, a modern arch can span 800 or 1000feet,  and a modern suspension bridge can span up to 7000ft.
 
        
             
        
        
        
A).  Convection is heating the soup in the pot.
When you stick the spoon into the hot soup, 
conduction heats the spoon all the way up to the end.
b).  Water conducts heat a little bit.  
But convection is much more responsible for the 
uniform distribution of temperature in the kiddie pool.
c).  The heat from the metal bench conducts directly 
to the buttus epidermis when you sit on it.
d).  You feel the heat on your face ... but not on the back of your 
neck ... on account of radiation from the fire and the hot grill.
        
             
        
        
        
Charles Law
Explanation:
Step 1:
It is given that the original volume of the gas is 250 ml at 300 K temperature and 1 atmosphere pressure. We need to find the volume of the same gas when the temperature is 350 K and 1 atmosphere pressure.
Step 2:
We observe that the gas pressure is the same in both the cases while the temperature is different. So we need a law that explains the volume change of a gas when temperature is changed, without any change to the pressure. 
Step 3:
Charles law provides the relationship between the gas volume and temperature, at a given pressure
Step 4:
Hence we conclude that Charles law can be used. 
 
        
                    
             
        
        
        
The answer is false because there are single celled organisms.
        
             
        
        
        
Answer:
Explanation:
RGB values are a combination of three different numerical values which represent Red Green and Blue which range from 0 to 255. When combining two separate colors with RGB values you would simply need to add each of these numerical values together to form an entirely new RGB value. For example,
(105, 200, 0) + (203, 30, 186) = (255, 230, 186)
You can see in the example above that every number in the first color is added to the number in the same position within the second color. If the addition of two numbers goes above 255 then the value maxes out at 255 and stays as is.
