11) Why do the planets move in fixed orbits around the Sun?

B) The gravitational pull of the Sun holds them in their orbits.

A) The magnetic pull of the Sun holds them in their orbits.

C) The nuclear force between the Sun and the planets holds them in their orbits.

D) The electrostatic force of attraction between the Sun and the planets holds them in their orbits.

The image shows the sequence of events describing the nebular origin of the solar system. Which statement describes the event at "D"?

B) The solar system is a cloud of dust and gas.

Consider the model of Kepler's 2nd Law seen here. Each colored wedge represents the same time interval. Kepler states that the area of each wedge must be equal. According to this, what conclusions can you draw about the movement of any planet?

A) An orbiting body travels faster as it gets closer to the central massive body.

B) An orbiting body travels along the perimeter of the segments at a constant velocity.

C) An orbiting body covers the same distance for each time interval because the speed changes.

D) The path of each planet around the sun is an ellipse because the sun is located at one focus.

the 1960s, Cosmic Microwave Background Radiation was discovered by the invention of radiotelescopes. This CMBR is now known to be

left over heat from the big bang

an unidentified response from alien life

25) The observed redshifts of galaxies are evidence for the Big Bang theory of the origin of the universe, because they indicate that

C) the galaxies are moving rapidly away in all directions.

A) the galaxies are still very hot.

B) the galaxies cannot be seen from the other side.

D) the galaxies turned red at the original moment of explosion.

in a popular song from 1970, the musical group Crosby, Stills, and Nash use the line, "We are stardust." Why is this statement true?

All elements, including those in our body, that are heavier than hydrogen are produced by fusion at the center of stars. Explosions of these stars then lead to the creation of planets and organisms.

A) The primary elements found in living organisms, H, N, O, and C, are constantly radiated through space from the sun.

B) The primary elements found in living organisms, H, N, O, and C, are constantly produced by sunlight in the earth's atmosphere.

All elements, including those in our body, that are heavier than hydrogen are produced by fission at the center of stars. Explosions of these stars then lead to the creation of planets and organisms.

28) According to the Big Bang theory of the origin of the universe, the universe has expanded from a hot dense state into a vast, cooler state. What would be considered scientific evidence supporting this theory?

B) Galaxies are moving away from each other.

A) Galaxies are moving toward each other.

C) Cosmic background X-ray radiation was detected in space.

D) The existence of common elements throughout the universe.

29) Which of these would be a good model to demonstrate the fact that the galaxies are moving apart as the universe is expanding?

C) The spots on a balloon move away as the balloon is inflated.

A) Dust particles move around in random directions

B) Pieces of paper scatter in random directions in the wind.

D) The balls on a pool table scatter when struck by the cue ball.

All BUT one statement is true regarding how stars produce the huge amount of energy they emit in the form of electromagnetic radiation. That is

C) Fusion in stars requires low velocity collisions of atoms.

A) Light elements fuse to form heavier elements.

B) The type of fusion that occurs is temperature dependent.

D) All stars derive their energy through the thermonuclear fusion.

36) Inside large stars, hydrogen is converted into helium. As this occurs some of the mass is converted into energy. this is known as

. B) a nuclear fission reaction.

D) an electromagnetic generator.

We know that there ARE elements more massive than iron and nickel. How might the evolution of stars contribute to the formation of these heavier elements?

C) Supernova explosions in the cores of massive stars provide the needed energy to form more massive elements.

A) Red giants combine the elements in all of their layers to produce heavier elements.

B) Nucleosynthesis requires a high-speed collisions and heavier elements form when two older stars collide.

D) Heavier elements are thought to be produced in stars that contain at least ten times as much matter as our Sun.

The image shows the sequence of events describing the nebular origin of the solar system. Which statement describes the event at "A"?

B) The solar system is a cloud of dust and gas

C) Contraction of the nebula into a spinning disk.

D) Condensation of dust into solid particles as the nebula cools.

In Figure 2 above, what is true about the AREA of areas A and B? (The two arrows marked “t” represent an equal amount of time.)

C) It depends on the eccentricity.
