The map be changed <u>by adding vectors that are all the same length and placing them above the current top row of vectors</u>
<h3>Further explanation</h3>A motion map represents the position, velocity, or acceleration of an object at various time readings
a small point or dot describes the position of the object. the object's velocity / acceleration is represented by an arrow / vector.
In this motion map, The arrows (vectors) are all the same length (same speed) and point in the same direction (direction to the right) for t = 0 (origin) to t = 4s
At t = 5s, the object has slowed down, and at t = 7s and 8s the object stops
At t = 9s-11 s, the object accelerates to the left
So the position of the next moving object will be above the previous movement, and the length of the same vector shows the same speed / acceleration
So that motion maps show constant acceleration after the object changes direction, it can be done by adding vectors that are all the same length and placing them above the current top row of vectors

Answer:
i = 4.9 A
Explanation:
The expression for the magnetic force in a wire carrying a current is
F = i L x B
bold letters indicate vectors.
The direction of the cable is towards the East, the direction of the magnetic field is towards the North, so the vector product is in the vertical direction (z-axis) upwards and the weight of the cable is vertical downwards. Let's apply the equilibrium condition
F - W = 0
i L B = m g
They indicate the linear density of the cable λ = 0.2 kg / m
λ = m / L
m = λ L
we substitute
i B = λ g
i =
let's calculate
i = 0.2 9.8 / 0.4
i = 4.9 A
