Solution :
Acceleration due to gravity of the earth, g 

Acceleration due to gravity at 1000 km depths is :


   
   
  = 8.23 m/s
Acceleration due to gravity at 2000 km depths is :


   
   
  = 6.73 m/s
Acceleration due to gravity at 3000 km depths is :


   
   = 5.18 m/s
Acceleration due to gravity at 4000 km depths is :


   
   
  = 3.64 m/s
         
 
        
             
        
        
        
Answer:
Cardiac Arrest, burns, and nerve damage.
Explanation:
Basically, the main risk is cardiac arrest, caused by the electric current interfering with the normal operation of the heart muscle. Other possible damages are burns due to the electric energy vaporizing the water inside the cells, and nerve damage caused by excessive current through the nerves.
 
        
             
        
        
        
Answer:
see solution below
Explanation:
The given resistors are connected in series.
Equivalent resistance in series = 30 + 55 + 15
Equivalent resistance in series Rt = 100 ohms
Since the potential difference in the circuit = 36V
Get the current in the circuit first
I = V/Rt
I = 36/100
I = 0.36A
Get the voltage across 30ohms resistor;
V30 = 0.36 * 30
V30  = 10.8volts
Hence the voltage across the 30ohms resistor is 10.8volts
Get the voltage across 55ohms resistor;
V55 = 0.36 * 55
V55  = 19.8volts
Hence the voltage across the 55ohms resistor is 19.8volts
Get the voltage across 15ohms resistor;
V15 = 0.36 * 15
V15  = 5.4volts
Hence the voltage across the 15ohms resistor is 5.4volts
