Basis for Cue Cards

Hi Folks! I had planned to finish these before the October hols! Sorry too much on. This is as far as I’ve got and I’ll update it a.s.a.p.
If you update it let me know. I’ll put the answers into a table of 2 columns so that if you fold down the middle they can be cue cards.

Going through past paper questions here is a list of the SQA recommended perfect answers
TypeYrQ No.
Trad20014 ba (OR F) is directly proportional to -x
Usual now to use -y rather than -x
Trad20015 aii(Electrostatic potential at a point) is the work done per unit charge moveing the charge from infinity to the point
Trad200111 aelectric field
vibrates in all directions in unpolarised light
vibrates in one plane only in polaried light
Trad20023 civelocity required by a body to escape earth gravitational field by reaching infinity
Trad20025 aidiffraction pattern produced by electon beam
Trad200210 ciiwavelength has incerased therfore the source is moving away from the observer
Trad20063 aiForce exerted on 1 kg (of mass) placed in the field
Trad200611 c (Path length) in oil depends on angle of incidence or thickness ∴different colours are seen due to interference
Trad20098 bOne tesla is the magnetic induction of a magnetic field in which a conductor of length one metre, carrying a current of one ampere (perpendicular) to the field is acted on by a force of one newton.
Trad20099 aiDivision of amplitude is when some of the light reflects from the top of the air wedge and some is transmitted/refracted into the air. OR Some of the light is reflected from a surface of a new material/medium and some of the light is transmitted/refracted into the new material/medium.
Trad200910 aA stationary wave is caused by interference effects between the incident and reflected sound.
Trad200910 bThe antinodes of the pattern are areas of maximum displacement/amplitude/disturbance The nodes of the pattern are areas of minimum/zero displacement/amplitude/disturbance
Trad20104 aTotal angular momentum before (an event) = total angular momentum after (an event) in the absence of external torques
Trad20106 biiE-field is zero inside a hollow conductor. E-field has inverse square dependence outside the conductor.
Trad201011 aunpolarised light => Electric field vector oscillates or vibrates in all planes polarised light => Electric field vector oscillates or vibrates in one plane
Trad20143 aiThe (minimum) velocity/speed that a mass must have to escape the gravitational field (of a planet).
Trad20144 aiThe unbalanced force/ acceleration is proportional to the displacement of the object and act in the opposite direction.
Rev20144 aiiThe distance from the centre of a black hole at which not even light can escape. or The distance from the centre of a black hole to the event horizon.
Trad20145 diElectron orbits a nucleus / proton , Angular momentum quantised or Certain allowed orbits / discrete energy level
Rev20146 aiiPhotoelectric effect or Compton scattering Collision and transfer of energy
Rev20146 diElectron orbits a nucleus / proton (1) Angular momentum quantised (1) or Certain allowed orbits / discrete energy level
Rev20148 aThe unbalanced force/ acceleration is proportional to the displacement of the object and act in the opposite direction.
Trad201411c Wavelengths in the middle of the visible spectrum not reflected or destructively interfere. Red and blue reflected / combined to (form purple).
Trad201413 aii The brightness would gradually reduce from a maximum at 0 degrees to no intensity at 90 degrees. It would then gradually increase in intensity from 90 degrees to 180 where it would again be at a maximum
Rev20151 cThe speed of the mass will be less. Second mark for correct justification. eg: Flywheel has greater moment of inertia  Flywheel will be more difficult to start moving  Smaller acceleration of flywheel  More energy required to achieve same angular velocity.
Rev20152 aMassive objects curve spacetime Other objects follow a curved path through this (distorted) spacetime
Rev20152 cTime passes more slowly at lower altitudes (in a gravitational field).
Lower gravitational field strength at higher altitude.
Trad20153 biiiPotential is work done (per unit mass) moving from infinity to that point. or Infinity defined as zero potential. Work will be done by the field on the mass. or A negative amount of work will be done to move an object from infinity to any point. or WD by gravity in moving to that point or Force acts in opposite direction to r.
Rev20155 aiiiDifficult scale to read/information from diagram can only be read to 1 s.f.
Rev20156 aiForce acting on (acceleration of) object is directly proportional to and in the opposite direction to its displacement. (from equilibrium)
Rev20157 aiil reduced (or f increased) for X-rays or >E transferred
D x reduced for X-rays
since D x D p ³ h/4 p
D p increases
Rev20157 bsince DEDt³ h/4 p
Borrowing energy for a short period of time allows particles to escape
Rev20158 aiTwo sets of coherent waves are necessary (for an interference pattern) or (Interference patterns can be produced by) Division of wavefront.
Rev20159 aiForce acts on particle at right angles to the direction of its velocity/motion or a central force on particle.
Rev20159 b(Component of) velocity at right angles to field/ v sin θ, results in circular motion/central force. (Component of) velocity parallel to field/ v cosθ is constant/no unbalance force (in this direction).
Trad20159 biMagnetic fields/induction are equal in magnitude (½) and opposite in direction
Rev201510 aiForce exerted per (unit) charge is constant at any point in the field
Rev201510 aivAny suitable answer eg  Systematic uncertainty in measuring d or V  Alignment of metre stick  The flame has a finite thickness so cannot get exactly to the zero point.  Factors causing field to be non-uniform.  A p.d. across the resistor for all readings.  Poor calibration of instruments measuring V or d.
Rev201510 bDeflection is less. E is less. Force/acceleration is less
Rev201512 biiiRate of change of current/magnetic field is at its maximum
Trad20165 aiFrames of reference that are accelerating (with respect to an inertial frame)
Trad20165 aiiIt is impossible to tell the difference between the effects of gravity and acceleration.
Trad20168 aiiThe precise position of a particle/ system and its momentum cannot both be known at the same instant. OR If the uncertainty in the energy of the
particle is reduced, the minimum
uncertainty in the lifetime of the
particle will increase (or vice-versa).
