Answer:
The answer is "
"
Explanation:
Please find the complete question in the attached file.
pi = pressure only at two liquids' devices
PA = pressure atmosphere.
1 = oil density
2 = uncertain fluid density
The pressures would be proportional to the quantity 
cm from below the surface at the interface between both the oil and the liquid.
Answer: 4.50*10^-6T (0.00000450071T)
Explanation: A current carrying conductor has been knowing to generate a specific amount of magnetic field.
This is given by the Bio-savart law (mathematical).
The Bio-savart law is a mathematical equation that gives the value of strength of the magnetic field created by a current carrying conductor.
B=(Uo* I) /2πr
Where
B= strength of magnetic field
Uo = magnetic permeability in free space = 1.257 *10^-6
r = distance between current carrying conductor and any reference point.
By doing the neccesary algebra, we have
B=(1.257 *10^-6 * 180)/ (2 * 3.142 * 8)
B= 2.2626 *10^-4 / 50.2857
B=4.5 * 10^-6T (0.00000450071T)
C .Clastic,why you see (clastic called Detrial ,made of broken rocks so the answer is C
"<span>The geomagnetic north is similar to the south pole of a magnet" is the statement among the following statements given in the question that correctly describes the Earth's magnetic field. The correct option among all the options that are given in the question is the second option. I hope the answer helps you.</span>
