Space, Time, and Motion
The name for the energy required to change the state of a substance without changing the temperature
What is the Latent heat?
What is the standard definition for the unified mass unit?
(1/12) of the mass of a carbon-12 atom
This is the name for the time for one complete oscillation
What is period
In rigid body mechanics, this quantity is defined as the rotational analog of mass and depends on the distribution of mass relative to the axis of rotation.
What is the Moment of Inertia?
The acceleration of free fall of a small sphere of mass 0.005kg when close to the surface of Jupiter is 25m/s/s. The gravitational field strength at the surface of Jupiter is...
A. 0.0002N/kg B. 0.13N/kg C. 25N/kg D. 5000N/kg
C. 25N/kg
This law states that the total entropy of an isolated system can never decrease over time
What is the Second Law of Thermodynamics?
In the Photoelectric Effect, increasing the light intensity (while keeping the frequency constant) increases the:
What is the number of Photoelectrons emitted
This effect explains the shift in frequency of a wave for an observer moving relative to its source.
What is the Doppler Effect?
These are the six gases that contribute to the greenhouse effect.
Methane, water vapour, carbon dioxide, nitrous oxide, ozone, chlorofluorocarbons
This quantity, defined as the product of a body's moment of inertia and its angular velocity, remains constant in a closed system.
What is Angular Momentum?
For an ideal gas undergoing this type of process, no thermal energy is transferred between the system and its surroundings
What is an Adiabatic Process?
In a nuclear reactor, this component (often made of graphite or water) is used to slow down "fast" neutrons so they can successfully cause further fission.
What is a Moderator?
In the double-slit experiment, if the distance between the slits is halved, the fringe width will . . .
What is it is doubled
In this final stage for stars like our Sun, the core collapses and the outer layers are shed, leaving behind a hot, dense remnant.
What is a White Dwarf?
In a perfectly elastic collision what must be true?
The temperature scale that is used when doing calculations with the Ideal Gas law - PV=nRT
What is the Kelvin Scale
This standard chart plots stars according to their luminosity versus their surface temperature or spectral class.
What is the Hertzsprung-Russell (H-R) Diagram?
An beam of monochromatic light is incident on a plane air-glass interface at 30 degrees. The refractive index of the glass is 1.50. The angle of incidence for the reflected ray would be . . .
19.5 degrees
These waves are formed by the superposition of two traveling waves of the same frequency and amplitude moving in opposite directions, resulting in points of zero amplitude called nodes.
What are Standing Waves?
In special relativity, this phenomenon causes a moving clock to be measured as ticking more slowly than a stationary one.
What is Time Dilation?
Under what conditions do real gasses behave most like ideal gasses?
What is under high temperature and low pressure
The half-life of a radioactive isotope is 10 days. Calculate the fraction of a sample that remains after 25 days.
18.5%
A string fixed at both ends is vibrating at its third harmonic. This is the total number of nodes present on the string.
What is 4?
The nth harmonic on a string fixed at both ends has (n + 1) nodes. The third harmonic has three loops, meaning nodes at the ends plus two in between.
In this type of nuclear reaction, a heavy nucleus splits into two or more smaller nuclei, releasing a large amount of energy.
What is Nuclear Fission?
