Answer:
A possible answer would be that chemical properties depend on phisical properties if and if only the phisical properties depend on the chemical ones ( see the laws of thermodinamics)

<span>Water in the oceans may become fresh water available to humans through the processes of evaporation, condensation and precipitation.
In these processes, water is heated to a very high temperature until it evaporates in order to kill the germs and remove the salts which remains after water evaporation. The next step in condensing the water vapor (which is now fresh) and precipitating this vapor to be used by humans.</span>
        
             
        
        
        
Answer:
a)Distance traveled during the first second = 4.905 m.
b)Final velocity at which the object hits the ground = 38.36 m/s
c)Distance traveled during the last second of motion before hitting the ground = 33.45 m
Explanation:
a) We have equation of motion
              S = ut + 0.5at²
      Here u = 0, and a = g
               S = 0.5gt²
     Distance traveled during the first second ( t =1 )
               S = 0.5 x 9.81 x 1² = 4.905 m
    Distance traveled during the first second = 4.905 m.
b)  We have equation of motion
             v² = u² + 2as
       Here u = 0, s= 75 m and a = g
            v² = 0² + 2 x g x 75 = 150 x 9.81
            v = 38.36 m/s
       Final velocity at which the object hits the ground = 38.36 m/s
c) We have S = 0.5gt²
                    75 = 0.5 x 9.81 x t²
                     t = 3.91 s
    We need to find distance traveled last second
    That is
           S = 0.5 x 9.81 x 3.91² - 0.5 x 9.81 x 2.91² = 33.45 m
    Distance traveled during the last second of motion before hitting the ground = 33.45 m
         
 
        
             
        
        
        
Answer:
The current is   
 
Explanation:
From the question we are told that  
      The radius of the loop is  
      The  earth's magnetic field is 
       The  number of turns is  
Generally the magnetic field generated by the current in the loop is mathematically represented as 
         
Now for the earth's magnetic field to be canceled out the magnetic field generated by the loop must be equal to the magnetic field out the earth
          
=>     
      Where   is the permeability of free space with value
 is the permeability of free space with value  
        
=>
