Which of the following is true about ruler? Tick all that applies.
Ruler is accurate up to one decimal unit
Ruler is more accurate than vernier caliper
Ruler is more accurate than a meterstick
Ruler is very convenient to use to materials ranging from 0.1-30 cm
TRUE or FALSE:
Vernier caliper is the same with micrometer caliper
True
False
What is the density of the material if the mass of a cylinder is 218.5 g and the volume is 24.654 cm^3? Express your answer following the least significant figure rule.
Answer: (a) g/cm^3
If the calculated density is 7.928 g/cm^3 from the measurements, what kind of metal is being used as sample specimen?
(a)
Calculate for the percent error if the computed density is 8.820 g/cm^3 and the accepted density os 8.9 g/cm^3. Express your answer to 2 significant figures.
Answer: (a) %
Which of the following best describes the difference between the measurements using ruler and vernier caliper?
Ruler's data: 8.2 g/cc
Vernier caliper: 8.91 g/cc
The percent difference of the two measurements is 8.30%.
The percent error of the two measurements is 8.30%.
The percent difference of the two measurements is 7.97%.
The percent error of the two measurements is 8.66%.
Check all that applies.
Vernier caliper can measure up to 3 decimal places of measurements.
Measurements from vernier caliper has lower percent error compared to measurements from ruler.
Measurement of masses using digital balance and triple beam balance affects the value of the percent error.
The percent error from the computed density using the ruler has greater accuracy compared to vernier caliper

Tick all that applies.
38.5 cc
38.5 cm^3
3.85 x 10^5 mm^3
3.85 x 10^-5 m^3
