Physics Review Game:Waves, Gravitation, and (some) Circular Motion Mr. Vannucci and Mr. Henry hosting
1. We know by now that the Earth has a mass of 6 x 1024 kg. We’ve observed that the Sun is at a distance of 1.5 x 1011 meters away, and that the force of the Earth on the Sun is 3.6 x 1022Newtons. Using this information, what is the mass of the Sun?
2. Nicole and Joe have a string between them that is 2.3 m long. Nicole counts the pulses she feels for 4 seconds, and it’s 15. What is the speed of the wave in this string?
3. From the previous problem, what is the frequency of that wave pulse in the string?
4. Add the following two waves together:A λ0.4 1.0-0.7 1.0
5. What wave would destructively cancel the wave below?:A λ0.6 1.0X Y
6. What wave would constructively increase the wave below by 1.5 times?A λ-0.8 1.0X Y
7. What wave would destructively cancel the wave below?:A λ0.6 1.0X Y
9. True/False: “Nodes like the mountains, Antinotes like the plains.”
10. A satellite of mass 600 kg is in orbit around the Earth has a tangential velocity of 7000 m/s. If the radius of its orbit is 8,250,000 meters;a) What is the circumference of this orbit?b) What is the centripetal force keeping this satellite in orbit?c) What is the period of orbit of this satellite in hours?
11. A satellite of mass 600 kg is in orbit around the Earth has a tangential velocity of 7000 m/s. If the radius of its orbit is 8,250,000 meters;d) How many revolutions does this satellite complete in a day?
12. Using the arrangement on the board, find the mass of the object that is balancing the meterstick.
Bonus. Your group will be given a string or a slinky. Your task is to measure the speed of a wave in that string/slinky. You must be sure to include:a. How far the two people areb. A drawing of your setupc. All the data that you collectedd. The calculation that you made
