The gravitational attraction between two objects would increase if both masses are –

increased, and the distance between them is decreased.

increased, and the distance between them is increased.

decreased, and the distance between them is decreased.

decreased, and the distance between them is increased.

Which would best model how the gravity of Earth affects the orbit of the Moon?

Swinging a yo-yo around in a circle

A tennis ball being hit by a tennis racket

Pulling down on a cord to raise window blinds

The diagram shows the Earth and Moon system in the solar system. What is the effect of Earth’s gravity on the Moon?

It causes the Moon to travel around the Earth.

It causes the Moon to experience day and night.

It's causes the Moon to change its shape.

It causes the Moon to spin on its own axis.

What is the primary difference in the main purpose of satellites and space probes?

Satellites orbit Earth for observation and communication, while space probes explore distant celestial bodies.

Satellites are for space exploration, while space probes are for Earth observation.

Satellites gather data from within our solar system, while space probes travel beyond it.

Satellites are robotic, while space probes are crewed.

Which of the following is a primary function of satellites?

Providing real-time data for Earth observation and communication.

Exploring distant planets and moons.

Exploring and analyzing the composition of asteroids.

Traveling beyond our solar system.

What is a key characteristic of space probes compared to satellites?

They are designed for targeted missions to specific celestial bodies far from Earth.

They remain in orbit around Earth for continuous monitoring.

They are mainly used for communication on Earth.

They are always crewed by astronauts.

What type of data are space probes typically equipped to collect?

Analysis of the atmosphere and surface of distant celestial bodies.

Real-time weather patterns on Earth.

Natural disaster observations on Earth.

Monitoring of Earth's communication networks.

Many telescopes have been launched into orbit around Earth or sent out into deep space. What is an advantage of using these telescopes rather than an Earth-based telescope to gather images?

The image resolution is higher because the Earth's atmosphere does no interfere with the image.

Space telescopes are always smaller and more compact than those on Earth.

It is easier for scientists to make adjustments to an orbiting telescope than one on Earth.

Orbiting telescopes usually last longer due to being in the cold of deep space.

Why is it challenging for two protons to fuse together?

They have the same positive charge and repel each other

They are too far apart in space

They have opposite charges and attract too strongly

Elements that are heavier than hydrogen and helium are formed through the process of nucleosynthesis, which takes place

when a larger star becomes a white dwarf.

around the edges of a black hole.

Main sequence stars are responsible for the formation of many elements. Which of the following best describes the process that forms these elements?

Isotopes of hydrogen fuse to form helium, releasing energy.

Energy is consumed to break heavy elements into hydrogen and helium.

Reactive molecules combine with oxygen in a combustion reaction.

Subatomic particles are drawn together by gravity, causing radioactive decay.

The diagram shows the change in the emission spectrum of a distant galaxy over time when observed from Earth.

The galaxy is moving towards Earth.

The galaxy is moving away from Earth.

A few years ago, three stars all appeared to be of a similar red color when viewed from Earth. The diagram shows the three stars, their present relative positions, and their color.

The stars are moving away from Earth.

The stars are moving closer to Earth.

The size of the stars decrease over time.

The size of the stars increases over time.

A researcher collects information on two different galaxies. Which finding supports the theory that the universe began with a period of rapid expansion?

The distance between galaxies is increasing over time.

The number of stars in each galaxy is similar.

The shapes of the galaxies are different.

There are planets in each galaxy along with stars.

The diagram shows the spectral lines of an element and how the element appears from Earth in Galaxies X, Y, and Z. Which Galaxy is moving the fastest?

They are all moving at the same speed.

What two elements make up most of the universe and how does this support the theory of universal expansion?

Hydrogen and Helium - the are easy to make

Hydrogen and Oxygen - they are needed to make water

Carbon and Oxygen - they are needed for photosynthesis

Hydrogen and Oxygen - they are complex and so is the univeres

Where is microwave background radiation found in the universe and what how does it support the expansion of the universe theory?

Everywhere because the universe started as energy in the center that spread outward in all directions

In one location because the universe started in one location

No where because all of the energy was converted to matter

Randomly because the process of fusion happens randomly throughout the universe

How are individual light waves represented by the students in Group A during the demonstration?

Each student represents a peak of a light wave.

Each student represents a different color of light.

Each student represents a light particle.

Each student represents a different frequency.

In the first demonstration, what do the students representing light waves demonstrate when they walk forward at a constant speed?

A normal wave with evenly spaced peaks.

A redshifted wave with increased wavelength.

A blueshifted wave with decreased wavelength.
