Answer:
0.80267 m
Explanation:
E(z) = Electric field = 1 µV/m
= 20 V/m
z = Depth
= Conductivity = 0.1 S/m
= 81
= Impedance of free space = 
Frequency is given by

Parameter is given by

From the first equation

The depth is 0.80267 m
Answer: What else is produced when sodium carbonate decomposes?
Explanation:
<span>Depth = 5.0 Ă— 10^2 m
Density of sea water = 1.025 x 10^3
Pd = Po + pgh
Atmospheric pressure is standard Patm = 1.01325 x 10^5 Pa
Since the normal pressure is retained in the hull, no need to bother about Po
Pd = pgh = 1.025 x 10^3 x 9.8 x 5.0 x 10^2 = 50.225 x 10^5
So now Pd / Patm = 50.225 x 10^5 / 1.01325 x 10^5 = 49.56
So it is 49.56 times larger.</span>
Answer:

Explanation:
We have given initial length of the steel guitar l = 1 m
Cross sectional area 
Young's modulus 
Force F = 1500 N
So stress 
We know that young's modulus 
So 

Now strain
