Waves and Light
Every color except for blue.
What are the methods of heat transfer? How do they transmit?
Conduction, convection, and radiation.
Conduction is through direct contact, convection is from a substance to another, and radiation is transmitted through waves.
What is needed to complete a circuit?
A wire that connects both positive and negative terminals.
What are magnetic fields visually represented by?
What color is white made by?
Every color.
What is specific heat capacity used for?
To find the amount of heat to raise the temperature of a substance.
What type of circuits are commonly used in homes and how are they connected?
Parallel circuits. Parallel circuits are always connected by two sets of common points, there are also a lot of paths for the current flow but only one source of voltage.
In what direction do magnetic fields point?
They move in the direction of the north pole.
Why are you not able to point a flashlight towards you and see light behind you?
Earth is round meaning that the light will have to bend. The flashlight needs to be very powerful to transfer light from afar.
What is specific latent heat used for?
To find the amount of heat that gets released during a change of state.
Why is it important to understand how electric fields work?
It is important because it allows us to know the force of a push or pull between charges.
What are magnetic fields created by?
Magnetic fields are created by charges in constant motion?
What is the Doppler effect?
It is when the pitch of an object changes from an observer's perspective.
What are the two possible things heat energy can do when added to a system?
Either increase the internal energy or external work is done if the system is left.
What does Ohm's law state in simple terms?
Ohm's law states that the voltage across a resistor is proportional to the current that moves through resistance.
What is an example of an object that creates magnetic fields?
Any type of magnet and/or a wire with electricity running through it.
What is sonic boom?
It is the sound that shock waves make when an object travels through air faster than the speed of sound.
Why does entropy naturally increase?
Heat energy will always flow so entropy means that it will go throughout everywhere.
What is the resistance of a circuit in which a current of 5 amperes flows through a resistor connected to 60 volts?
12 ohms.
What are some similarities between magnetic fields and electric fields?
Magnetic fields point in the direction of the north pole, electric fields move in the direction of the positive charges. Both have like poles that repel and unlike poles that attract.
