Adisplacement b of 100m from the origin at an angle of 37° above the x axis is the result of three successive displacement : b1 of 100 along the negative x axis, b2 of 200m at an angle of 150° above the x axis and a displacement b3. find b3[ 355m, 353.5]

(353.1 m, -39.8 m)

Explanation:

Let's start by writing the components of the resultant displacement, B:

We know that this displacement is the result of three successive displacements, which can be written in terms of their components, as follows:

and , whose components are unknown.

The components of the resultant displacement must be equal to the sum of the components of each vector along each direction, therefore:

and

So, the vector b3 has components (353.1 m, -39.8 m).

d) physical means can be used to separate the components of air.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
