FSA Review 6th grade topics Horvath

An engineering student is gathering data on the motion of a model car traveling down a ramp. If energy is conserved, the potential energy of the car at the top of the ramp should equal the kinetic energy at the bottom of the ramp. After the first trial, the student calculates that the kinetic energy at the bottom of the ramp is less than the potential energy at the top of the ramp. Which of the following best explains this difference?

• The student did not include the effect of friction in his calculation.
• The student accidently accelerated the car at the top of the ramp.
• The measured height of the ramp was less than the actual height.
• The car gained a small amount of mass at it moved down the ramp.

As a person exercises, the carbon dioxide level in the blood increases. Which of the following systems are signaled by the nervous system to respond to this increase in carbon dioxide?

• digestive and immune systems
• immune and respiratory systems
• circulatory and excretory systems
• respiratory and circulatory systems

Which of the following statements is true when comparing societal laws to scientific laws?

• Scientific laws are valid all over the world, while societal laws differ from region to region.
• Both scientific laws and societal laws are accepted after qualified professionals vote on them.
• Both scientific laws and societal laws are accompanied by severe legal consequences for breaking them.
• Societal laws are based on numerous experiments, while scientific laws are accepted only by the votes of well-known scientists.

Two oppositely charged objects are separated by a small distance. The objects are then moved three times farther apart from each other. Which of the following statements best describes what happens to the electrical force between the objects?

• The force of attraction increases.
• The force of attraction decreases.
• The force of attraction stays the same.
• The force of attraction becomes a force of repulsion.

Much of the Florida landscape is built upon limestone. Frequent rains seep down and erode the limestone as the rainwater travels to underground caverns or aquifers. Which of the following landforms could be created as a result of this process?

• A delta would form as the limestone sediment is carried by aquifers.
• A swamp would be created as the rain water combines with the water in the aquifer.
• Sinkholes would form as a result of the collapse of the surface layer in an underground cavern.
• Stalagmites would be created as the water dripped down from the cavern ceiling and formed a mound.

Two students are standing next to each other on a level field. One of the students throws a tennis ball forward toward a line that is 2.0 meters (m) away. At the same time, the second student throws a bowling ball in the same direction. Both balls take the same time to travel the 2.0 m. When both balls are thrown, only the student that throws the bowling ball feels a noticeable push backwards. Which of the following statements best explains why only the second student feels a noticeable push backwards?

• The bowling ball exerts a much larger reaction force due to its larger mass.
• The bowling ball undergoes a much larger acceleration due to its larger mass.
• The bowling ball converts more inertia into kinetic energy due to its larger mass.
• The bowling ball requires more force to overcome gravity due to its larger mass.

The rainforest is hot, humid, and has frequent rainfall. In what way do the atmosphere and the hydrosphere contribute to this type of climate?

• The hydrosphere sends water to the clouds through the process of transpiration, fueling the water cycle.
• The Sun’s rays are trapped by the atmosphere, keeping temperatures and humidity high for most of the year.
• The Sun supplies energy for the evaporation and transpiration of water, causing frequent rainfall and hot, humid temperatures.
• The rainforest is in close proximity to the equator, allowing the hydrosphere to release frequent rainfall, fueling the water cycle.

The rainforest is in close proximity to the equator, allowing the hydrosphere to release frequent rainfall, fueling the water cycle.

• The gravitational force would increase.
• The gravitational force would decrease.
• The gravitational force would be unchanged.
• The gravitational force would cause higher tides.
