A student measures the velocity of the water in a stream as 2.5 meters per second. The actual velocity of the water is 3.0 meters per second. What is the approximate percent deviation of the student's measurement?

• 0.50%

• 17%

• 20%

• 50%

A student measures the volume of water as 72 milliliters when the true volume is 75 milliliters. Which equation should be used to determine the student's percent deviation?

The diagram provided represents a solid object with a density of 3 grams per cubic centimeter. What is the mass of this object?

• 0.5 g

• 2 g

• 18 g

• 36 g

Science investigators initially use classification systems to

• extend their powers of observation

• make more accurate inferences

• organize their observations in a meaningful way

• make direct comparisons with standard units of measurement

A rock sample has a mass of 16 g and a volume of 8 cm³. When the rock is cut in half, what is the volume and density of each piece?

• 8 cm³ and 0.5 g/cm³

• 8 cm³ and 1.0 g/cm³

• 4 cm³ and 2.0 g/cm³

• 4 cm³ and 4.0 g/cm³

An example of a noncyclic change is the occurence of

• earthquakes

• ocean tides

• phases of the moon

• seasons of the year

A list of 3 observed relationships is shown below.

*Erosional rate = depositional rate

*Amount of insolation = amount of terrestrial radiation

*Rate of condensation = rate of evaporation

In which situation would each relationship exist?

• when a cyclic change occurs

• when a change of state occurs

• when dynamic equilibrium is reached

• when global warming ceases and global cooling beings

The diagrams represent four solid objects made of the same uniform material. The volumes of the sphere and the bar are not given.

What will occur when the sphere is heated?

• its mass will increase and its volume will remain the same

• its mass will decrease and its volume will remain the same

• its mass will remain the same and its volume will increase

• its mass will remain the same and its volume will decrease
