Acharge is moving in a magnetic field that points to the left. what direction can the charge move and experience no magnetic force? check all that apply a. up b. down c. left d. right e. into the screen f. out of the screen .
what must be known to determine the direction of the magnetic force on a charge? check all that apply. a. the type of the charge b. the amount of the charge c. the direction of the magnetic field d. the velocity of the charge e. the strength of the magnetic field

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

another example of kinetic energy would be,

kinetic energy   >     moving energy

hope that !                                         : )

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
