Question 19 D An electron is accelerated in an electric field through a potential difference of +2400 V. Which of the following justifies why the change in kinetic energy can be calculated using AU = QAV?
А
The electric field exerts a force on the electron that is proportional to the electron's charge
B
The change in potential energy of the field electron system is equal to the change in kinetic energy of the particle
с
The work done on the particle by the field is equal to the electric force times the distance the electron moves.
D
Changes in potential and kinetic energies are always equal.

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
