Question:

The fact that the magnetic field generates a force perpendicular to the instantaneous velocity of the particle has implications for the work that the field does on the particle. As a consequence, if only the magnetic field acts on the particle, its kinetic energy will .

__ increase over time

__ decrease over time

__ remain constant

__ oscillate

Remain constant

Explanation:

By the formula of work done,

Change in kinetic energy = Work done

final kinetic energy - initial kinetic energy = Force × distance × cosθ

final kinetic energy - initial kinetic energy = Force × velocity × time × cosθ

∵ θ = 90 degree

cos 90 = 0

final kinetic energy - initial kinetic energy = 0

final kinetic energy = initial kinetic energy

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

the independent variable, or the one that is intentionally manipulated is the speed.
