Volcanic eruption most likely to happen when the plates are moving intense in the ground. Maybe an earthquake are most likely for a volcanic eruption to occur.

Explanation:
The frequency of a sodium vapor lamp, 
We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :
So, the wavelength of light is equal to 
.
Answer:
l3/l = 2
Explanation:
Suppose B1 is the magnetic field due to cable 1 and B2 is the field due to cable 2. Therefore, the magnitude of the field at a distance from the cable is equal to:
B = (uo*I)/(2*pi*r)
B1-2 = (B1^2 + B2^2)^1/2 = ((((uo*I)/(2*pi*r)^2 + (uo*I)/(2*pi*r)^2))))))^1/2 = (2^1/2)*(uo*l)/(2*pi*r)
From this equation we can say that the direction of the field will be from the corner that is empty and cable 3:
B3 = B1-2
(uo*l3)/(2*pi*(2^1/2)*r = (2^1/2)*(uo*l)/(2*pi*r)
From here we have that the relationship between both currents will be equal to:
l3/l = 2
