when is the Final physics Exam
the voltage across a conductor is directly proportional to the current at constant temperetaure (for Ohmic conductors)
what is Ohm's Law
a collision where the total kinetic energy of the system is conserved
what is an Elastic Collision
a surface that travels with a wave and is perpendicular to the direction of travel
what is a wavefront
the process of increasing the proportion (to 3%) of U-235 in a Uranium fuel.
what is fuel enrichment
The number of particles in a mole (6.02 x 1023 )
What is Avagadro constant
conservation of energy, the sum of all variations of potential difference in a closed loop is zero
What is Kirchoff Loop rule
the work done per unit mass in moving a mass from infinity to a point in space (always negative)
what is gravitational potential
having a constant phase relationship
What is Phase relationship
the closed-system that collects energy from the reacter to the water.
what is a heat exchanger
the probability that an individual nucleus will decay in a given time interval
What is the decay constant
circuit elements (sometimes sensors) to produce variable potential differences
What is a potential divider
kg⋅m2⋅s^−3
What are the base SI Units for Power
radian per second
what is Angular velocity
transfer of thermal energy through atomic vibrations
What is thermal conduction
numerically equivalent to magnetic field strength
what is magnetic flux density
circuit elements (sometimes sensors) to produce variable potential differences
what is a potential dividers
energy that a charge has due to its position in an electric field
electric potential energy
two sources are resolved if the principal maximum from one diffraction pattern is no closer than the first minimum of the first minimum of the other pattern.
What is the Rayleigh criterion
fraction of the total incoming solar radiation received by a planet that is reflected back out into space
What is albedo
Occurs when an electron in an atom of the absorbing material absorbs a photon. Energy of this photon must be identical to the difference between energy levels.
what is the absorption spectra
