2nd Semester Final Exam Review

The chart shows the heat index, which uses the relationship between air temperature and relative humidity to predict how hot a day feels. For example, a day with an air temperature of 85°F will feel cooler

at 0% relative humidity. It will feel much hotter at 100% relative humidity.

Kerry is watching a softball game on a hot day. To her, the air temperature feels like it’s about 100°F.

However, she sees a bank thermometer that says it’s only 90°F. What is the most likely relative humidity at the game?

• 40%

• 60%

• 80%

• 100%

The stages of evolution of a star are determined by the mass of the star at the beginning of its life cycle. Which stage of evolution is the oldest form of a massive star?

• red giant

• supernova

• neutron star

• white dwarf

All stars start forming in the same manner. Some follow the life cycle of the Sun, while others turn into neutron stars or black holes. Which property determines the fate of a star as it develops?

• mass

• location

• luminosity

• temperature

An asteroid orbiting the Sun obeys Kepler’s laws of planetary motion. A diagram of the orbit is shown

below.

The asteroid moves in a counterclockwise motion around the Sun. Which option ranks the speeds of the asteroid at locations W through Z from fastest to slowest?

• Z > W > X > Y

• Y > X > W > Z

• X > Y > W >Z

• W > Y > Z > X

Both Earth and Jupiter follow elliptical orbits around the Sun. The orbit of Jupiter is farther from the Sun than the orbit of Earth.

How does this orbit affect the motion of Jupiter compared to Earth?

• Jupiter rotates more slowly on its axis.

• Jupiter revolves more slowly in its orbit.

• The plane of the orbit of Jupiter varies more over time.

• The tilt of the axis of Jupiter is more perpendicular to the plane of orbit.

A new planet is discovered orbiting a single star. The planet has one moon. According to Kepler’s first law, what do scientists know about the orbit of the planet around the star?

• The orbit is circular with the star at the center of the circle.

• The orbit is elliptical with the star at one focus of the ellipse.

• The planet takes 12 times longer to orbit the star than the moon takes to orbit the planet.

• The planet orbits the star in a direction opposite to the direction of the moon’s orbit of the planet.

Scientists measured the patterns of spectral lines given off by distant galaxies and concluded that almost all of these galaxies are moving away from Earth. What did the scientists observe directly?

• a shift toward longer wavelengths of light

• a shift toward shorter wavelengths of light

• the absence of wavelengths in the visible light range

• the compression of wavelengths in the visible light range
