    III. Using an incorrectly calibrated probe in an experiment.
    1. AI and III
    2. BI, II and III
    3. CII and III
    4. DI and II
    5. EI
    6. FII
    7. GIII
  2. 2Which statements about uncertainties are true?

    I. Every measurement has an uncertainty.
    II. Uncertainties are expressions of random error.
    III. Uncertainties are always expressed as positive values.
    1. AI and II
    2. BI and III
    3. CII and III
    4. DI, II and III
    5. EI
    6. FII
    7. GIII
  3. 3What is the uncertainty in a measurement taken on an electronic balance that reads mass (in grams) to two decimal places?
    1. A+/- 0.5 g
    2. B+/- 0.05 g
    3. C+/- 0.005 g
    4. D+/- 0.1 g
    5. E+/- 0.01 g
    6. F+/- 0.001 g
  4. 4If a scale reading is quoted as 23.75 ± 0.05 g, which value could not be possible for this reading?
    1. A23.72 g
    2. B23.69 g
    3. C23.80 g
    4. D23.78 g
  5. 5Find z if:
    x = (2.0 +/- 0.2) cm
    y = (3.0 +/- 0.6) cm
    z = x - 2y = [blank_start](-4.0 +/- 0.9)[blank_end] cm

    Hint: answer will resemble this format: (#.# +/- #.##) units
    1. A(-4.0 +/- 0.9)
  6. 6Which of the following units can be used to measure speed?
    1. Am/s
    2. Bms^-1
    3. Ckm/hr
    4. Dms
    5. Em/s*s
  7. 7If w = (4.52 +/- 0.02) cm and x = (2.0 +/- 0.2) cm, find z if z = wx

    z = [blank_start](9.0 +/- 0.9)[blank_end] cm^2

    Hint: Answer will be in this format: (#.# +/- #.#) units
    1. A(9.0 +/- 0.9)
  8. 8If x = (2.0 +/- 0.2) cm and y = (3.0 +/- 0.6) s, find z if z = x/y.

    z = [blank_start](0.7 +/- 0.2)[blank_end] cm/s

    Hint: Answer will be in this format: (#.# +/- #.#) units
    1. A(0.7 +/- 0.2)
  9. 9Which of the following are vectors?
    1. ASpeed
    2. BTime
    3. CVelocity
    4. DDistance
    5. EDisplacement
    6. FAcceleration
  10. 10Take the equation 2x = (g - y) / 2 and solve for g.

    Hint: For your answer, put a space between every character, so 7a+ 3b will look like 7 x + 3 b.

    g = [blank_start]4 x + y[blank_end]
    1. A4 x + y
