PART 2 OF ENERGY AND FORCES UNIT TEST Please help!

1. In 3–4 sentences, describe how a particle accelerator works and give an example of the applications of the discoveries made with them. (4 points)

2. A magnet is removed from a refrigerator door and placed on a table. In 1–2 sentences, explain how the potential energy of the system changes in this process. (2 points)

3. Using a simple model of an electromagnet, describe the factors that increase the magnetic field strength of an electromagnet.(2 points)

1. at least two charged interacting parts

2. from the electric fields of charged subatomic particles

3 an arrow released from the bow

4Electrical fields of charged particles interact, bonding those with opposite charges.

5 the interaction of the electric fields of protons and electrons

6 The energy stored in the system increases.

7 Kinetic energy increases because the magnets move in the direction of the field.

8 Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.

9  

The energy stored in the field decreases because the magnet moves in the direction of the field.

10 The energy stored increases and then decreases.

11 The wire was not connected to the source.

12  The electromagnet will become more powerful.

the rest are written, hope this helps (:

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

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.
