Answer:
time = 224 days 
Explanation:
given data 
thick = 30 m
piezometers =  280 m 
head between  two = 1.4 m
aquifer hydraulic conductivity = 50 m
porosity =  20%
solution
we get here average pole velocity that is get by using Darcy law that is 
Va =  ................1
   ................1
here Va is average pole velocity and k is hydraulic conductivity and  is porosity
 is porosity  
here v is =  ...........2
   ...........2
v = 50 ×  
 
v = 0.25 m/day 
and here average linear velocity Va will be 
Va =  
   
Va =  
  
Va = 1.25 m/day  
travel time for water will be 
time =  
   
time = 224 days 
 
        
             
        
        
        
Explanation:
1) x= y/(1+y)
2)x= -y/(1-y)
3) x=y/(1-y)
4)square root (2E/m-v^2)
5) (( x^2b^2- a^2b^2)/a^2) square root
6) square root( x^3/a)
 
        
             
        
        
        
The statements which are true about client-side DNS include all of the following;
B. Client-side DNS should be configured to point towards the DNS server that is authoritative for the domain that client wants to join.
C. Check out DNS settings using the NSLookup command.
D. Check out DNS settings using the DIG command.
E. The cache.dns file has the IP addresses of the 13 root DNS servers.
B. If a web site can be reached by IP address and not by host name, then DNS or the Hosts file would be the problem.
<h3>What is a DNS server?</h3>
In Computer technology, a DNS server can be defined as a type of server that is designed and developed to translate domain names into IP addresses, so as to allow end users access websites and other internet resources through a web browser.
This ultimately implies that, a DNS server simply refers to a type of server that is designed and developed to translate requests for domain names into IP addresses for end users.

N
 refers to the number of turns
V
 is voltage
s
 and 
p
 refer to the secondary and primary coil.
From the conservation of energy we get:
