Answer:
23932242.5 Pa
Explanation:
 = Atmospheric pressure =
 = Atmospheric pressure = 
 = Pressure of seawater
 = Pressure of seawater
 = Density of sea water =
 = Density of sea water = 
h = Depth of shipwreck = 
g = Acceleration due to gravity = 9.81 m/s²
The absolute pressure is given by

The absolute pressure at the depth of the shipwreck is 23932242.5 Pa
 
        
             
        
        
        
So they give us this
V=IR
V= 1.8
I=0.4
R=?
So we insert the thing that we know.
1.8=0.4*R
We need to leave our unknown value alone. So if our value of 0.4 is multiplying the unknown value it passes to the other side dividing.
So we have this.
Lastly we solve.
R=4.5ohms
The formula to find R is V=IR
V/I=R
So the resistance will be the Voltage divided by the Current
