An electromagnetic wave of wavelength 435 nm is traveling in vacuum in the –z direction. the electric field has an amplitude of 2.70×10−3v/m and is parallel to the x axis. what are the frequency and the magnetic-field amplitude of this wave?

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
