What 2 planets have you chosen? For each destination planet, what are the orbital parameters, mean...
A resonance orbit is one in which planets have a fixed ratio of orbital periods. For example, for 2 planets with an orbital resonance of 3:1, the outer planet's orbital period would be 3 times that of the inner one. That is, the inner planet can complete 3 exact orbits whilst the outer one completes only one. This is a special type of orbital "locking". The two planets orbiting the nearby star are observed to be in a 2:1 resonance...
Two planets orbit in circular orbits around a star have speeds of 5v(planet A) and 2v(planet B). Express your answers in fractional form, simplified as much as possible. What is the ratio of the orbital radii of the planets? rB/rA = ___/___ What is the ratio of their periods? PB/PA = ___/____
How can Kepler’s law of planetary motion be applied to the case of geo-stationary satellite? What are the orbital parameters required to determine a satellite orbit? Name and explain them. Determine the maximum and minimum range in kilometer from an earth station to a geo-synchronous satellite. To what round trip propagation times do these correspond? Mention the effect of eclipse on the orbital motion of a satellite. Mention the effect of gravitational force due to sun and moon on the...
Suppose that you have a planet in a circular orbit about a star with the mass of the Sun. The orbital speed is 141 km/s. If you could increase the planet’s speed, what speed would you need to make it to escape the gravitational pull of its parent star?
1. Why is the orbital period of each planet not exactly proportional to the radius of its orbit? (Think Kepler's 3rd law). 2. When people say that Venus is the twin of Earth, what is the only characteristic that would validate that statement? 3. If you didn't want to disrupt your sleep cycle, what planet besides earth would you be happy living on? 4. What other terrestrial planet would have seasons similar to earth? 5. Explain the result of Venus'...
Let's say there is a mystery planet way out past Neptune. I'll give you two orbital parameters and you must calculate any others you think you need, then determine the orbital period of this "planet" in Earth years. Type your answer in once you think you have it. Good luck! e = 0.25 b = 5.71 x 1012 m
Part 8 of 8 - Analyze Tamsen and Vera imagine visiting another planet, planet X, whose gravitational acceleration, 9x, is different from that of Earth's. They envision a pendulum, whose period on Earth is 2.243 s, that is set in motion on planet X, and the period is measured to be 1.530 s. What is the ratio of gx/9Earth? Neglect any effects caused by air resistance. 9x ge If the average density of planet X is equal to Earth's average...
Each of the following diagrams shows a planet orbiting a star. Each diagram is labeled with the planet's mass (in Earth masses) and its average orbital distance (in AU). Assume that all four stars are identical. Use Kepler's third law to rank the planets from left to right based on their orbital periods, from longest to shortest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top of the other(s) to...
3) The next two questions pertain to the following situation. Star S has two planets, X and Y, that both orbit Sin uniform circular motion. Planet X of mass my = 2.7 x 1021 kg orbits star S in uniform circular motion at a distance rx = 2.8 * 1012 m and with speed vx = 9.7 x 104 m/s. The mass of star S is Ms and its radius is Rs = 2 x 10 m, as shown in...
need answer ASAP. Do not know how to caculate answers.
Q4. Because of your physics skills you have been selected to scout locations for the first movie to be shot or another planet. However while there an alien sneaks up behind you and hits you on the head. When you wake up you cannot remember what planet you are on, but you do have a table of gravitational acceleration on the different planets and a ball you can throw. Use...
