An electric field will be induced in an area where the magnetic field is changing with respect to time. This is:

• Faraday's Law

• Coloumb's Law

• Maxwell's Corollary

• Ohm's Law

How can an induced magnet be made stronger?

• adding more induction

• adding more primary coils

• adding more secondary coils

• there isn't a way to make it stronger

What is magnetic induction?

• an area surrounding a magnet in which a magnetic force acts on a moving charge

• branch of physics dealing with the interaction of electric and magnetic fields

• the creation of a magnet by bringing a magnet close to another non-magnetic material

• a piece of metal that has atoms aligned such that it attracts other pieces of metal

Which of the following characteristics are true about a parallel circuit?

1. 1. The current that goes through each resistor is the same.

1. 2. The drop in the voltage across each resistor is proportional to the resistance of that resistor.

2. 3. The current in the circuit is equal to the sum of the currents flowing in each part of the circuit.

• 1 only

• 1 and 3

• 3 only

• 1, 2 and 3

Which statement correctly describes the electric force, electric field, electric potential energy, and electric potential difference?

• the field and potential difference are intrinsic; force and potential energy require more than one charge

• the force and potential energy are intrinsic, field and potential difference require more than one charge

• the field and potential energy are intrinsic, force and potential difference require more than one charge

• the force and potential difference are intrinsic, field and potential energy require more than one charge

Which of the following is an example of charging by friction?

• bringing a charged rod in contact with the Earth

• rubbing your hair with a rubber balloon

• touching your friend after dragging your feet across the carpet

• bringing a charged comb next to a bowl of salt and pepper

A refrigerator lowers the temperature, or internal energy, of substances, which are largely isovolumetric. Which sentence best describes this process?

• The substance gives heat to the refrigerator and does not change volume in the process.

• The substance takes cold from the refrigerator and does not change volume in the process.

• The substance takes heat from the refrigerator and changes volume in the process.

• The substance gives heat to the refrigerator and changes volume in the process.
