Answer:

1.) The current is doubled

2.) moving a magnet up and down near the wire

3.) An electric current in the wire produces a magnetic field.

4.) Distance between Particles (m)

Explanation:

1.) When 6 V battery is connected to a 24 ohm resistor to create a circuit, using ohms law, V = IR

Current I = 6/24 = 0.25 A

When the The 6 V battery is replaced with a 12 V battery,

Current I = 12/24 = 0.5 A

Therefore, The current is doubled

2.) Electric current will be induced when moving a magnet up and down near the wire

3.) An electric current in the wire produces a magnetic field.

4.) Distance between Particles (m)

The force of attraction between two different masses is inversely proportional to the square of the distance between them.

1. When the 12-Volts battery is used in the electrical circuit instead of the 6-Volts battery: C. The current is doubled.

2. The action which can produce an electric current in a loop of wire is: D. moving a magnet up and down near the wire.

3. The claim which is best supported by the student’s investigation is: A. An electric current in the wire produces a magnetic field.

4. The student should label the x-axis of the graph of the amount of electrical force between two charged particles: D. Distance between Particles (m).

1. To calculate the magnitude of current in the electrical circuit, we would apply Ohm's law:

[tex]V = IR\\\\I=\frac{V}{R}[/tex]

Where:

  • V is the voltage measured in Volts.
  • I is the current measured in Ampere.
  • R is the resistance measured in Ohms.

When V = 6-Volts and R = 24-Ohms:

[tex]I=\frac{6}{24}[/tex]

I = 0.25 Amp.

When V = 12-Volts and R = 24-Ohms:

[tex]I=\frac{12}{24}[/tex]

I = 0.50 Amp.

Therefore, the the magnitude of current in the electrical circuit is doubled.

2. The action which can produce an electric current in a loop of wire is the movement of a magnet up and down in proximity to the wire because the magnetic field would induce a current in accordance with Faraday's law of electromagnetic induction.

3. The claim which is best supported by the student’s investigation is that an electric current in the insulated wire produces a magnetic field and as such it would attract the steel paperclips.

4. In accordance with Coulombs law, the student should label the x-axis of the graph of the amount of electrical force between two charged particles as the distance between particles, which is measured in meters (m).
