EXAM QUESTIONS AND CORRECT VERIFIED ANSWERS/ ALREADY GRADED A+ PSC 1121
FINAL EXAM PREP (MOST RECENT!!), with the strongest emphasis placed on Apply
fundamental principles of physics to solve complex, multi-step problems, Critically evaluate
physical models and their limitations in novel scenarios and Integrate knowledge across
subdisciplines to explain natural phenomena. Every item follows the wording style and level of
reasoning you meet in the real paper, and each one is paired with a clear rationale so the correct
choice is never a guess. Work through the set at your own pace, mark the questions that slow you
down, then come back to them until the reasoning feels automatic. Learners who revise this way
walk into the exam room recognising the pattern behind the questions instead of meeting them for
the first time. Keep going - steady, honest practice is what turns a difficult paper into a comfortable
pass.

,Q1 APPLY FUNDAMENTAL PRINCIPLES OF PHYSICS TO SOLVE COMPLEX, MULTI-STEP
PROBLEMS
In a double-slit experiment, electrons of kinetic energy E produce an interference
pattern with fringe spacing y. If the electron energy is increased to 4E, what is the
new fringe spacing?
A. y/2 CORRECT
B. y/4
C. 2y
D. 4y
RATIONALE: Fringe spacing is inversely proportional to momentum (y 1/p). Since p = (2mE),
doubling energy quadruples momentum, so p doubles and y halves.
Q2 APPLY FUNDAMENTAL PRINCIPLES OF PHYSICS TO SOLVE COMPLEX, MULTI-STEP
PROBLEMS
A star's spectral line is observed at 656.5 nm, while the laboratory wavelength is
656.3 nm. What is the star's radial velocity and direction?
A. 91.4 km/s, receding CORRECT
B. 91.4 km/s, approaching
C. 45.7 km/s, receding
D. 45.7 km/s, approaching
RATIONALE: Using / = v/c, = 0.2 nm, = 656.3 nm, so v = 0.2/656.3 × 3×10^5 km/s 91.4 km/s.
Redshift means receding.

,Q3 APPLY FUNDAMENTAL PRINCIPLES OF PHYSICS TO SOLVE COMPLEX, MULTI-STEP
PROBLEMS
A Carnot engine operates between 600 K and 300 K. If it absorbs 1000 J per cycle,
how much work is done per cycle?
A. 500 J CORRECT
B. 750 J
C. 250 J
D. 1000 J
RATIONALE: Carnot efficiency = 1 - T_c/T_h = 0.5. Work = efficiency × heat absorbed = 0.5 ×
1000 J = 500 J.
Q4 APPLY FUNDAMENTAL PRINCIPLES OF PHYSICS TO SOLVE COMPLEX, MULTI-STEP
PROBLEMS
A charged particle moves in a uniform magnetic field perpendicular to its velocity.
If the field strength is doubled, what happens to the radius of its circular path?
A. It is halved CORRECT
B. It is doubled
C. It remains the same
D. It quadruples
RATIONALE: The cyclotron radius r = mv/(qB). Doubling B reduces r by half, assuming constant
speed.

, Q5 APPLY FUNDAMENTAL PRINCIPLES OF PHYSICS TO SOLVE COMPLEX, MULTI-STEP
PROBLEMS
Calculate the binding energy per nucleon for helium-4 (mass = 4.002603 u). Given:
proton mass = 1.007276 u, neutron mass = 1.008665 u, 1 u = 931.5 MeV/c².
A. 7.07 MeV CORRECT
B. 6.81 MeV
C. 28.3 MeV
D. 1.02 MeV
RATIONALE: Mass defect = (2×1.007276 + 2×1.008665) - 4.002603 = 0.030379 u. Energy =
0.030379 × 931.5 = 28.3 MeV. Per nucleon = 28.3/4 = 7.07 MeV.
Q6 APPLY FUNDAMENTAL PRINCIPLES OF PHYSICS TO SOLVE COMPLEX, MULTI-STEP
PROBLEMS
A spaceship moves at 0.8c relative to Earth. If the crew measures a time interval of
6 hours, what duration passes on Earth?
A. 10 hours CORRECT
B. 7.5 hours
C. 3.6 hours
D. 6 hours
RATIONALE: Time dilation: t = t, with = 1/(1-0.8²) = 1/0.6 = 1.667. So Earth time = 6 × 1.667 =
10 hours.
