Q1. Which of these quantities is a vector?
  • A.  Speed
  • B.  Distance
  • C.  Displacement
  • D.  Kinetic energy
Show answer & explanation
✓ Answer: C. Displacement
Displacement has both magnitude and direction, making it a vector, unlike distance which is a scalar path length. Speed and kinetic energy are also scalars since they have no associated direction.
Q2. A wire of original length 2.00 m and cross-sectional area 1.5 x 10^-6 m^2 extends by 3.0 mm when a tensile force of 90 N is applied, within the elastic limit. What is the Young modulus of the material?
  • A.  2.7 x 10^7 Pa
  • B.  4.0 x 10^10 Pa
  • C.  6.0 x 10^7 Pa
  • D.  1.2 x 10^9 Pa
Show answer & explanation
✓ Answer: B. 4.0 x 10^10 Pa
Stress = F/A = 90/(1.5x10^-6) = 6.0x10^7 Pa. Strain = extension/length = 0.003/2.00 = 1.5x10^-3. Young modulus = stress/strain = 6.0x10^7/1.5x10^-3 = 4.0x10^10 Pa. Quoting stress or strain alone without dividing gives the wrong distractor values.
Q3. A student measures the terminal p.d. of a battery for several different currents and plots V against I, obtaining a straight line. How can EMF and internal resistance be found from this graph?
  • A.  EMF is the gradient and internal resistance is the y-intercept
  • B.  EMF is the y-intercept and internal resistance is the negative of the gradient
  • C.  EMF is the x-intercept and internal resistance is the gradient
  • D.  EMF is the area under the graph and internal resistance is the gradient
Show answer & explanation
✓ Answer: B. EMF is the y-intercept and internal resistance is the negative of the gradient
From V = ε − Ir, plotting V (y-axis) against I (x-axis) gives a straight line with y-intercept ε (when I = 0) and gradient −r, so internal resistance is the magnitude of the negative gradient.
