State Flashcards
(14 cards)
State and use Flemings left hand rule to determine the force on a current carrying conductor at right angles to a magnetic field
Do it You know you want to ;) Motion - thuMMMb for Motion Field Current - FFFFirst for Field Current - seCCCond for Current
State and use faradays law of electromagnetic induction
(Formula book)
Induced emf is proportional to the rate of change of magnetic flux linkage
State and use lenz’s law
The direction of the induced emf is such as to cause effects to oppose the change producing it
State equation for total capacitance in parallel
Ctotal = C1 + C2 etc
State and use the equation for total capacitance in series
1/Ctotal = 1/C1 + 1/C2 etc
State the quantities conserved in nuclear decay
Charge, total no. neutrons and protons, total mass-energy, momentum, lepton number
State fundamental particle equation for beta minus decay
n -> p + (e-) + anti-neutrino
udd -> uud + (e-) + anti-neutrino
State fundamental particle equation for beta plus decay
p -> n + (e+) + neutrino
uud -> udd + (e+) + neutrino
State that electric fields are created by electric charges
Electric charges exert forces on each other
An electric field is a region of space where a stationary charge experience a force
State the group of particles that electrons and neutrinos belong to
Leptons
State Olbers paradox
A static, homogenous Infinitely old universe With and infinite number of stars Distributed in an infinitely large space Would be bright rather than dark
State Hubbles Law
The speed of recession of a galaxy is proportional to its distance from Earth/Observer
State the cosmological principle
Universe is isotopic (same in all directions)
Homogenous (evenly distributed)
State the area under the P.D against charge graph
Energy stored by the capacitor
