Which type of satellite is used for sending messages from one place to another Communication observation weather reconnaissance2. A lunar month is about 28 days. If the moon were farther from the Earth than it is now, the lunar month would be More than 28 days. Less than 28 days. About 28 days. Difficult to predict without much more information.3. A woman on the surface of the Earth has a mass of 50 kilograms and a weight of 490 newtons. If the woman were floating freely inside a space habitat far away from Earth, she would have Less weight and the same mass. Less weight and more mass. More weight and less mass. None of these Less weight and less mass.4. A lunar month is about 28 days. If the moon were closer to the Earth than it is now, the lunar month would be None of the above More than 28 days. Less than 28 days. Unchanged at 28 days5. An Earth satellite is in an elliptical orbit. The satellite travels fastest when it is It travels at constant speed everywhere in orbit. None of the above Nearest the Earth. Farthest from the Earth.6. 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. Neither7. Which satellites to Sky uplink their services to? None of the above Astra 2F Astra 2E All of the above8. The fastest moving planet in a solar system is The planet nearest the sun. The planet farthest from the sun. The most massive planet. The smallest planet. Any planet, for they all move at the same speed9. A satellite near the Earth makes a full circle in about an hour and a half. How long would a satellite located as far away as the moon take to orbit the Earth? More information about the satellite is needed. Less than an hour and a half The same hour and a half None of these About 28 days10. The Blue Streak satellites was lauched by which country France Australia Japan U.S.A11. Planets would crash into the sun if it weren't for The inverse-square law. The fact that they are beyond the main gravitation of the sun. Their relatively small masses. Their tangential velocities. Their vast distances from the sun.12. Where is the GPS satellite Navstar operation located? California New York Wyoming Colorado13. How high up do the communication satellites that Sky use orbit at? 230 miles 2230 miles 223000 miles 22300 miles14. A satellite describes an elliptical orbit about a planet. The satellite travels much faster when it is directly over a Great plain or plateau. Large island. High mountain range. Large ocean. None of the above choices affects its speed very much.15. The speeds of the planets about the sun depend on Their distances from the sun. None of the above are correct. Their periods of rotation. The masses of the planets.16. 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 planet. 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.17. What did Bradford Parkinson receive as an award or his impacton the GPS satellite project? A Charles Stark Draper Prize A Chocolate Bar A Medal A Nobel Piece Prize18. The Asterik satellites was lauched by which country U.S.A Japan Australia France19. An Earth satellite is simply a projectile Approaching the Earth from outer space Floating motionless in space near the Earth. Freely falling around the Earth. None of the above20. 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 antenna is not properly attached. The customer is not using the proper dialing pattern. The customer does not have full view of the sky. The customer has run out of minutes. The battery needs to be charged.21 out of 20Time is Up!
