If no magnetic field were applied, would you expect the electron beam to be deflected upward or downward by the electric field?

oposite to the direction of the electric field

Explanation:

The answer depends on the electric field direction, if the electric field points upward, we expect the electron beam to be deflected downward. If the electric field points downward,  we expect the electron beam to be deflected upward.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
