0.6V - correct answerThe threshold voltage needed before a diode will conduct
1 Coulomb - correct answerThe amount of charge that passes in 1 second when the current is 1 ampere
1 eV in Joules - correct answer1.6x10(-19) Joules
1 Volt - correct answer1 joule of energy moving across 1 coulomb of charge through the component
1/R=1/R1+1/R2... - correct answerTotal resistance in a parallel circuit is
3fm - correct answerThe distance at which the maximum attractive value of the strong nuclear force
rapidly falls towards zero
Acceleration - correct answerChange in velocity per unit time.
Air bags - correct answerIncreases the impact time and the area over which the resultant force acts,
decreasing the pressure and force on the passanger.
Alpha Emission - correct answerEmission due to very large atoms, such as uranium, as the nuclei are too
big for the strong nuclear force to hold them together
Alternating Current looks like what on an oscilloscope - correct answerThis gives a repeating waveform
on the oscilloscope
Amplitude - correct answerThe maximum displacement of a vibrating particle. In a transverse wave this
is the height of the wave crest.
, Annihilation - correct answerThe process in which a particle and anti-particle pair meet and 2 photons
are produced
Antimatter - correct answerHas the same mass, with opposite charge and spins in the opposite direction
Antinode - correct answerFixed point on a stationary wave pattern where the amplitude is at its
maximum.
Baryon Number - correct answerBaryon = +1
Anti Baryon = -1
Mesons or Leptons = 0
Baryons - correct answerHadrons which contain 3 quarks, including protons and neutrons
Beta Emission - correct answerEmission due to neutron rich isotopes, so one neutron is changed into a
proton
Braking distance - correct answerThe distance travelled by the car in the time it takes to come to a stop
safely.
Brittle - correct answerA brittle material snaps without any noticeable yield.
Cancellation - correct answerWhen a crest meets a trough and the resultant displacement is zero.
Centre of mass - correct answerThe point on a object through which a single force on the body has no
turning effect.
Coherent - correct answerTwo sourrces of waves are coherent if they emit waves with a constant phase
difference (i.e they have the same frequency and wavelength)
