Answer:

Explanation:
The force excerted by a magnetic field on a charged particle is given by the Lorentz force:

Lets consider the z-direction of our coordinate system the same direction of the magnetic field, that is:

Let us consider that the velocity of a given particle is:

Therefore, since k×k = 0

And since i, j , k are a rigth hand system:
i × j = k
j × k = i
k × i = j --> i × k= -j

Threfore, if the particle has charge q and velocity v = (vx,vy,vz), the magnetic force it will feel will be

Answer:
I think B but I could be wrong
Explanation:
Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
Explanation:
<span>Nonliving things also have unlimited duration of existence. While living things die and decompose, nonliving things such as rocks, mountains, air and water have existed for millions of years. They may grow, but they do so only by accretion, which is the process of growth by accumulating added layers of matter.</span>
