Hypothesis: The amount of oxygen produced will increase consistently with the light intensity.

Do the results in the data below support the hypothesis?

No; levels of oxygen increased and then began to level off despite increasing light intensity.

All celestial objects are attracted to each other by gravity. Asteroids A and B are 5 meters apart. Asteroids C and D are also 5 meters apart. If asteroids A and B both have a mass of 5 kilograms and asteroids C and D both have a mass of 7 kilograms, between which set of asteroids is the gravitational attraction the greatest?

Between asteroids C and D, because gravitational attraction is greatest with increased mass.

The atmosphere can affect the precision of telescopes. Scientists conducted experiments to determine the precision of different telescopes. Precision was determined by how similar the measurements were to each other at each location. The more similar the measurements were for a certain distance or altitude across the trials, the more precise the telescope was.

The first table shows the effect on telescope precision based on distance from a major city. The second table shows the effect of altitude on telescope precision.



THE EFFECT OF DISTANCE FROM A MAJOR CITY ON TELESCOPE PRECISION [TABLE 1]


THE EFFECT OF ALTITUDE ON TELESCOPE PRECISION [TABLE 2]

Based on the data in the two tables, where would be the most precise location to build a telescope?

A. A telescope built 0.8 km from a major city and 27.4 m above sea level will be the most precise.

B. A telescope built 60.5 km from a major city and 27.4 m above sea level will be the most precise.

C. A telescope built 0.8 km from a major city and 1645.9 m above sea level will be the most precise.

D. A telescope built 60.5 km from a major city and 1645.9 m above sea level will be the most precise.

D. A telescope built 60.5km from a major city and 1645.9m above sea level will be the most precise.

The atmosphere surrounding Earth helps to maintain the various climates found around the world and keep Earth from becoming extremely cold all over. How does the atmosphere help to keep Earth insulated and warm?

A. The atmosphere creates heat as Earth moves through space, helping to insulate Earth.

B. The atmosphere traps the heat generated by Earth's core and helps maintain Earth's climate.

C. The atmosphere helps spread the warmth from the water near the equator to other parts of the Earth's climate.

D. The atmosphere helps trap heat energy from the Sun and energy radiated from Earth to maintain the climate.


D. The atmosphere helps trap heat energy from the Sun and energy radiated from Earth to maintain the climate.

The energy from sunlight is transmitted as electromagnetic waves, such as ultraviolet light and visible light. Explain the difference between ultraviolet light and visible light.


Visible light has longer wavelengths than ultraviolet light.

Paul’s class investigated the effects of friction on the motion of a toy car. Using ramps with different surfaces, students determined the amount of time, in seconds (s), for the toy cars to reach the bottom of each ramp. All variables were controlled except the tested variable (independent variable). One group of students concluded that toy cars on a sandpaper surface are fastest.

Which of the following statements BEST evaluates the group's conclusion?

A. The results support the conclusion.

B. More data need to be added to the conclusion.

C. The conclusion is valid for the data recorded.

D. The results fail to support the conclusion.

D. The results fail to support the conclusion.

Crawford's teacher tells him that all objects exert gravitational forces on one another and these forces depend on the distance between the two objects. Crawford wants to know why, if this is true, he cannot slide the books on his desk toward himself without reaching out and touching them, but the Earth can move objects without making contact in this way. Which statement offers the best explanation for Crawford's question?


A. The force that Crawford exerts is more than the force of friction on that object.

B. The force of Crawford's gravity is directly related to his mass, which is much less than Earth's.

C. Earth is much closer to the objects it moves than Crawford is to the objects he is trying to move

D. Crawford's gravitational force on the books is cancelled by the book's equal and opposite gravitational force on him.

B. The force of Crawford's gravity is directly related to his mass, which is much less than Earth's.

As a distant star moves away from Earth, the light given off by the star has a measurably lower frequency.

What happens to the wavelength and energy of the waves of light when the frequency becomes lower?


The wavelength becomes longer, and the energy decreases.

The Keck Observatory is home to the largest Earth-based twin telescopes. The telescopes are located away from city lights, above the clouds where the atmosphere is clear, calm, and dry. In 1999, additional steps were taken to help the telescopes overcome any distortions caused by changes in the atmosphere by adding a laser sighting system. Now, the Keck telescopes can probe distant galaxies and capture images with more detail than even the Hubble space telescope. Scientists can now use the Keck telescopes to investigate many questions.

What is one question the Keck telescopes would NOT help scientists answer?

A. How do galaxies rotate?

B. What is the weather on Neptune?

C. What is the core of Saturn made of?

D. What other solar systems have planets?

C. What is the core of Saturn made of?
