An electric field is expressed in rectangular coordinates by E = 6x2ax + 6y ay +4az V/m.Find:a) VMN if point M and N are specifi
ed by M(2,6,1) and N(-3, -3, 2).b) VM if V = 0 at Q(4, -2, -35)c) VN if V = 2 at P(1,2,4).Please show all steps
1 answer:
Answer:
a.) -147V
b.) -120V
c.) 51V
Explanation:
a.) Equation for potential difference is the integral of the electrical field from a to b for the voltage V_ba = V(b)-V(a).
b.) The problem becomes easier to solve if you draw out the circuit. Since potential at Q is 0, then Q is at ground. So voltage across V_MQ is the same as potential at V_M.
c.) Same process as part b. Draw out the circuit and you'll see that the potential a point V_N is the same as the voltage across V_NP added with the 2V from the other box.
Honestly, these things take practice to get used to. It's really hard to explain this.

Answer:
t = 56.6 min
Explanation:
Fick's second law is used to calculate time required for diffusion
where
= 1.15%
= 0.18%
= 0.35%
x = 0.40 mm = 0.0004 n
therefore we ahave
from error function table we hvae following result
for erf z z
0.8209 0.95
0.8247 x
0.8427 1
therefore
x = 0.959
thus
t = 56.6 min
