100 (cm) is equal to this length.
What is 1 (m)?
100
Of the two rulers shown, this one gives the more precise measurement.
What is Ruler B?
100
The slope of this graph represents this physical property of the material.
What is density?
200
The number of significant figures in 105.02.
What is 5?
200
A density reported simply as “8.9” is missing this.
What are units of g/mL?
200
Without calculating, 35 mi/hr × 1.609 km/mi × 1 hr/3600 s ends with these units
What is 1000 (km/s)?
200
Measurements that are close to their accepted values are described by this word.
What is "accurate"?
200
The mathematical model relating density, mass, and volume.
m=ρ*V
300
Calculate 12.11+0.3+1.245 and report it correctly.
What is 13.7?
300
The axis of a graph that displays the independent variable that often has units of time (for motion graphs, at least).
What is the x-axis?
300
Convert 375 cm to meters.
What is 3.75 m?
300
Measurements that are consistently very close to one another are described by this word.
What is "precise"?
300
At zero displaced volume, the intercept represents this physical quantity.
What is initial mass of water?
400
Calculate 2.30×4.1 and report the answer with the correct significant figures.
What is 9.4?
400
A mass-vs-volume graph has these slope units.
What are (g/mL)?
400
Convert 72 (km/h) to (m/s).
What is 20 (m/s)?
400
Logger Pro reports σ=0.20. For our 95% convention, this is 2σ.
What is 0.4?
400
Water rises from 22.0 (mL) to 28.5 (mL) when an object is submerged. This is the object's volume. 
What is 6.5 (mL) or 6.5 (cm³)?
500
The value 1500 written in scientific notation so that it clearly has three significant figures is this.
What is 1.50×103?
500
A graph has mass in grams on the vertical axis and time in seconds on the horizontal axis. Its slope would have these units.
What are (g/s)?
500
750 nm written in meters using scientific notation is this value.
What is 7.50×10−7 (m)?
500
A measurement of 8.4±0.2 (cm) could reasonably include this value: 8.1, 8.5, or 8.8 (cm).
Response: What is 8.5 (cm)?
500
This is the denser of the two materials.
