5.You have a tricked out rocket for your trip to Mars. At the last minute, you decide to bring your XBox 360 and its 103 games. What happens to your rocket's possible acceleration? Select one:
a. As there is no gravity in space, the extra mass will make no change in the rocket's acceleration.
b. Mass is increased, so the rocket will accelerate faster.
c. Any change will depend on how close to the Earth's gravity pull the rocket is located.
d. Mass is increased, so the rocket will accelerate slower.
e. The rocket is cooler, so it will go faster.
9.How do comets differ from asteroids? Select one:
a. Only difference is in where they are located.
b. Asteroids are made of icy material. Comets are made of rocky material.
c. Both are made of rocky and icy material, but comets are larger in size than asteroids.
d. Asteroids are made of rocky material. Comets are made of icy material.
e. Both are made of rocky and icy material, but comets are smaller in size than asteroids.
17.The Big Dipper is select one: a. A visual group of stars that are not related.
b. A giant dipper in the sky.
c. A group of stars that were formed next to each other.
d. A group of stars that defines a stellar cluster.
24.What best explains the Solar System's rocky planets being closer to the Sun? Select one:
a. Rocks are heavy and settled to the center of the Solar System.
b. During the formation of the Solar System, Jupiter formed first, which then tended to prevent planet formation in the inner solar system, leaving only small rocks near the Sun.
c. During the formation of the Solar System, most of the material tended to collect far from the Sun because of the large centrifugal forces, which did not provide the necessary material to build large Jovian planets near the Sun, so only small rocky ones formed there.
d. During the formation of the Solar System, the heavier elements tended to sink nearer the Sun and, being rare, only provided enough material to build the relatively small rocky planets.
e. During the formation of the Solar System, the rocky planets formed near the Sun where, because of the high temperatures, only heavier elements were able to condense.
28.Which number is closest to the age of our Solar System? Select one:
a. 5 billion years
b. 1 billion years
c. 10,000 years
d. 1 million years
e. 5 million years
31.Which of the following does not describe a terrestrial planet? Select one:
a. high density
b. mostly rock and metals
c. solid surfaces
d. many moons
32.Other than Earth, which other Solar System object has liquid on the surface? Select one:
a. Jupiter
b. Titan
c. Venus
d. Mars
e. No other body has liquid on the surface, just ice.
33.You see a shooting star. What is it? Select one:
a. a meteor
b. a dead star
c. a meteorite
d. an atmospheric phenomena
e. an asteroid
35.What is the origin of asteroids? Select one:
a. Material ejected from the Sun during Coronal Mass Ejections.
b. Chunks of material expelled from massive volcanoes when the planets were first formed, when they were hotter.
c. Big Bang debris.
d. Leftover planetesimals that never accreted onto planets.
e. Shattered remains of collisions between planets.
Explanation / Answer
5.
Answer: d
Explanation: Rocket moves with a constant acceleration with appropriate mass. The Sudden increase of mass by adding of Xbox and its 103 games gives the slower acceleration. Increase of mass causes decrease of acceleration.
9.
Answer: d
Explanation: Asteroids are made of metals and rocky materials but comets are made ice materials. Asteroids are very nearer to the Sun while the comets are far away from the Sun. These reason comets maintain ice crystals with in it.
17.
Answer: b
Explanation: A Big Dipper is consolation of seven stars in the night sky. It is probably a giant dipper in the sky.
24.
Answer: e
Explanation: The rocky planets, which are nearer to the Sun absorbs high amount of temperature from the Sun. Due to the high temperatures, the elements were able to condense.
