What is the law that relates pressure and temperature?
Gay-Lussac’s law
It states that when a gas is heated, the gas particles have greater kinetic energy, leading to more frequent collisions with the walls, which increases pressure.
What is the law that relates volume and temperature?
Charles’ law
It states that when a gas is heated, the gas particles have greater kinetic energy, causing them to collide with the walls more often, thus increasing volume.
What is the law that relates volume and pressure?
Boyle’s law
It states that when a gas is compressed, the volume decreases, resulting in more frequent collisions with the walls, which increases pressure.
What should you include when talking about EM radiation?
The word wave.
What is the purpose of a diode?
It only conducts in one direction.
What must you mention when talking about shielding?
Penetration.
What does a non-ohmic conductor mean?
It does not obey ohm’s law.
What are detectors of EM radiation?
Part of spectrum, Detector, Application
Examples include:
* Radio - Aerial - Communication
* Microwave - Microwave diode - Mobile phone Communication
* Infrared - CCD - TV remote lasers
* Visible - CCD - Endoscopy
* Ultraviolet - CCD - Source of vitamin D
* X-ray - CCD - Detecting broken bones
* Gamma - Geiger-Muller tube connected to counter - Medical tracer
What must you mention for balanced force explanations?
Both the equality of the forces and their opposite directions.
Do you use scientific notation or prefixes?
Scientific notation.
What does a count rate measure, background activity or background radiation?
Background activity.
What is AC electron flow?
Back and forth.
What are two words often used in force diagrams?
Thrust and weight.
What can you mention when talking about making something faster?
Making it more aerodynamic, streamlining it, possibly adding wheels.
Are voltage dividers in series or parallel?
Series.
When do you account for background radiation?
When given the count rate from an experiment.
What is a moon?
A natural satellite that orbits a planet or dwarf planet.
How do you identify errors in a table?
Finding the pattern and using that to find the outlier.
