Module 5
Speed that satisfies the condition that K > U (or equal) for an object on a planet.
What is escape velocity?
Constant current which, if maintained in two straight parallel conductors of infinite length of negligible circular cross section and placed one metre apart in a vacuum, would produce between these conductors a force equal to 2 × 10−7 newton per metre of length.
What was the definition of an ampere.
"The laws of physics remain constant in all inertial reference frames" and "The speed of light c is constant"
What are Einstein's 2 postulates of special relativity?
Photon emissions from a hydrogen atom due to electrons transitioning to the second energy shell.
What is the Balmer series?
Mr "No look parabola"
Who is Raul Siljeg?

ux=ucosø
uy=usinø
Incomplete flux linkage, resistive heat production and eddy currents
What are limitations of the ideal transformer model?

A 3 quark combo deal
What is a Baryon?
Mr "Slow Strider"
Who is Isaac Kari?
Kepler's 3 laws of planetary motion
What are:

?
The most important minus sign on your data sheet
What is Lenz's Law
The value of the gradient of a Kmax vs f graph for the photoelectric effect.
What is planks constant?
Scientists who fired electrons at a nickel target which scattered and produced an interference pattern, hence validating De Broglie's matter-wave hypothesis.
Who are Davisson & Germer?
Mr's "Music is more important than physics so we get to leave class early"
Who are Julian Eckermann and Cooper Hemmy?
If the magnitude of centripetal force on an object remains the same but the radius of its path is increased, what will be the resulting effect on its period?
What is an increase in period?
The path a charge takes relative to an electric field and the path is takes relative to a magnetic field.
E field path is parabolic due to constant acceleration in one direction, B field path is circular (or spiralled if v at an angle to B) due to constant centripetal acceleration.
Two equations on your formula sheet that provide evidence for the wave model of light.
What are Young's interference eqn and Malus' Law?
Two types of nucleosynthesis that occur in main-sequence stars and one type that occurs in post main-sequence stars.
What are the proton-proton chain, CNO cycle and the triple alhpa process?
Mr "Arabic Commenter"
Who is Mark Seliman?
The amount of work done on a 100 kg object undergoing uniform circular motion parallel to the earth's surface with a constant velocity of 20 m s-1 and at a radius of 0.5 m.
What is none?
3 key features of a simple DC motor.
What are the rotor (coils around iron core), stator (external B field), split ring commutator (reverse the circuit connection)
