Answer:
(a) the net charge inside the closed surface. 
Explanation:
In Gauss' Law, Qencl refers to the net charge inside the Gaussian surface. This surface is usually taken as a symmetric geometric surface, but this is merely for simplicity. Gauss' Law holds for any closed surface. Inside this surface there can be insulators as well as conductors. Regardless of the geometry or the materials inside, Qencl refers to the net charge inside the closed surface. The charge outside the surface is irrelevant for Gauss' Law, therefore all the charge in the physical system is not included in Gauss' Law. 
 
        
             
        
        
        
Answer: Not balanced
Explanation: In order to balance this equation the coefficients are the following:
6 CO2 + 6H2O = > C6H12O6 + 6O2 
 
        
             
        
        
        
Answer:
the average kinetic energy of water particles - C. 
 
        
             
        
        
        
The given velocity is 465 m/s.
Part a.

Answer: 1674 km/h
Part b.

Answer: 40,176 km/day. 
 
        
        
        
Average speed is defined as total distance moved in total interval of time
so it is given as

now here is we show distance by "d" and time by"t"
then we will have mathematical expression as follows
