Consider a moon that orbits one of our most distant planets in an elliptical path. The distance that the moon covers each day is The same regardless of its distance from the sun. Greatest when the moon is closest to the planet. Greatest when the moon is furthest from the planet. The same regardless of its distance from the planet. 2. An airplane that flies at 100 km/h in a 100 km/h hurricane crosswind has a ground speed of 141 km/h. 0 km/h. 200 km/h 100 km/h. 3. How many GPS satellites are currently functioning in space? 24 25 28 4 17 4. Rocco is using a satellite phone from his porch. He calls in complaining that his service only works for a few minutes at a time and then drops out. What is the most likely problem? The customer has run out of minutes. The antenna is not properly attached. The customer does not have full view of the sky. The battery needs to be charged. The customer is not using the proper dialing pattern. 5. It takes Pluto a longer time to orbit the sun than the Earth does because Pluto Goes much slower. None of the above Has much further to go. Choices A and B are both correct. 6. A satellite describes an elliptical orbit about a planet. The satellite travels much faster when it is directly over a Large island. Large ocean. Great plain or plateau. None of the above choices affects its speed very much. High mountain range. 7. The fastest moving planet in a solar system is The planet nearest the sun. The planet farthest from the sun. Any planet, for they all move at the same speed The most massive planet. The smallest planet. 8. The circular path of a satellite orbiting the Earth is characterized by a constant Acceleration. All of these Speed. Radial distance. 9. How high up do the communication satellites that Sky use orbit at? 223000 miles 2230 miles 22300 miles 230 miles 10. Nigeria lauched its first satellites in 2001 2004 2003 2002 11. Which type of satellite is used to monitor atmospheric conditions communication observation reconnaissance weather 12. The Blue Streak satellites was lauched by which country France Australia Japan U.S.A 13. When was the first GPS satellite launched into space? 1979 1984 1884 1978 14. The radial velocity of an Earth satellite is its velocity Perpendicular to the surface of the Earth. Attributed to satellites moving in any direction. Parallel to the surface of the Earth. None of these 15. A lunar month is about 28 days. If the moon were farther from the Earth than it is now, the lunar month would be Difficult to predict without much more information. About 28 days. More than 28 days. Less than 28 days. 16. The Rohini satellites was launched in what year 1959 1989 1979 1969 17. Both Newton and Kepler considered forces on the planets. Kepler hypothesized the direction of the forces was Away from the sun Toward the sun. Along their directions of travel. Neither 18. A vertically oriented rocket that is somehow able to maintain a continuous upward velocity of 8 km/s will None of these Be unable to escape the Earth. Escape from the Earth. Eventually maintain a fixed orbit around the sun. 19. If a satellite's radial velocity is zero at all times, its orbit must be Parabolic. Elliptical. Geosynchronous. Circular. 20. A "weightless" astronaut in an orbiting shuttle is Beyond the pull of gravity. Shielded from the Earth's gravitational field. Pulled only by gravitation to the shuttle which cancels the Earth's gravitational pull. Like the shuttle, pulled by Earth's gravitation. 1 out of 20 Time is Up! Time's up
