Let's choose east as positive x-direction and south as positive y-direction. We can resolve the two displacement along these two axes:

- Displacement 1 (3.5 km, 55^{\circ} south of west

d_{1x}=-(3.5 km)( cos 55^{\circ})=-2.01 km

d_{1y}=(3.5 km)( sin 55^{\circ})=2.87 km

- Displacement 2 (2.7 km, 16^{\circ} east of south

d_{2x}=(2.7 km)( sin 16^{\circ})=0.74 km

d_{1y}=(2.7 km)( cos 16^{\circ})=2.60 km

So, the total components on the two directions are

d_x = -2.01 km+0.74 km=-1.27 km

d_y=2.87 km+2.60 km=5.47 km

And the magnitude of the hiker's resultant displacement is

d=\sqrt{(1.27 km)^2+(5.47 km)^2}=5.6 km

Answer:

 i = 0.477 10⁴ B

the current flows in the  counterclockwise

Explanation:

For this exercise let's use the Ampere law

                    ∫ B . ds = μ₀ I

Where the path is closed

Let's start by locating the current vines that are parallel to the z-axis, so it must be exterminated along the x-axis and as the specific direction is not indicated, suppose it extends along the y-axis.

From BiotSavart's law, the field must be perpendicular to the direction of the current, so the magnetic field must go in the x direction.

We apply the law of Ampere the segment parallel to the x-axis is the one that contributes to the integral, since the other two have an angle of 90º with the magnetic field

Segment on the y axis

        L₀ = (y2-y1)

        L₀ = 3-0 = 3 cm

Segment on the point x = 2 cm

        L₁ = 3-0

        L₁ = 3cm

       B L = μ₀ I

       B 2L = μ₀ I

        i = 2 L B /μ₀

        i= 2 0.03 / 4π 10⁻⁷   B

        i = 4.77 10⁴  B

The current is perpendicular to the magnetic field whereby the current flows in the  counterclockwise
