A strong electrolyte is one that completely in solution. a) reacts.b) decomposes.c) disappears.d) ionizes.

a) the direction of the magnetic field is east.

b) The magnitude = 0.310 T

Explanation:

Step 1: Data given

Mass per unit length = 0.600 g/cm

current = 1.90 horizontally to the south

Step 2:

The force of gravity = magnetic force

m*g = i*L*B

m/L * g = i*B

B = ((m/L)*g) /i

⇒ with m/L = the mass per length unit = 0.600 g/cm = 0.0600 kg /m

⇒ g = 9.81 m/s²

⇒ i = the current = 1.90 A

B = (0.0600 * 9.81) / 1.90

B = 0.310 T

According to the right hand rule, the direction of the magnetic field is east.
