Final Exam Review 1

What is the relationship between the force of gravity and distance between the satellite and Earth?

• The force of gravity increases as the satellite moves farther away from Earth.

• The force of gravity decreases as the satellite moves farther away from Earth.

• The force of gravity stays the same as the satellite moves farther away from Earth.

• The force of gravity changes randomly as the satellite moves farther away from Earth.

Predict what the force of gravity acting on the satellite would be if the satellite is 1,000 km from Earth.

• 400 N

• 3,000 N

• 200,000 N

• 1,000,000 N

While floating in outer space you throw a ball and measure its velocity at 21 m/s. You track the ball for the next month as it travels through empty space in a straight line. What would the velocity of the ball be on day 3 of its journey?

• More than 21 m/s

• 21 m/s

• 0 m/s

• Atomic radius increases

• Atomic radius decreases

• Atomic radius stays the same

• Atomic radius changes randomly

Why has the model of the atom changed over time?

• The structure of the atom has changed over time.

• Early scientists lied to the public about what the atom looked like.

• Improvements in scientific technology have led to new discoveries improving scientists understanding of the structure of the atom.

• Atoms have grown over time which has made them easier to study.

The Hubble Space Telescope is named after a famous American astronomer named Edwin Hubble. Hubble discovered that the speed that galaxies were moving away from Earth is directly proportional to the distance of the galaxy from Earth. Galaxies farther away from Earth were moving away faster. What is the name of this key phenomenon that Hubble discovered?

• Blueshift

• Cosmic Microwave Background Radiation

• Universal Law of Gravitation

• Redshift
