A satellite in orbit around the earth is at an altitude of 107 percent of the earth's radius. Rounding off our old friend "g" to ten meters per second squared, what is the acceleration due to earth's gravity at the satellite? Your answer should be in meters per second squared, but do not put the unit, just the number.
Earth's orbit is (on average) 1 Astronomical Unit from the Sun. For reference, 1 Astronomical Unit is about 93 million miles. Jupiter's orbit is about 5 Astronomical Units from the Sun. Suppose that the gravitational force between the Earth and the Sun is equal to 50,000 N (it's way more than that but we are just pretending here). If we move Earth to Jupiter's orbit, what will be the new value of the gravitational force between the Earth and the Sun? Remember to include units of force (Newtons or N) in your answer.
How many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale. Be creative!
Determine the distance h for which the spacecraft S will experience equal attractions from the earth and from the sun. Use Table D/2 of Appendix D as needed. Assume L = 210 000 km. Sun Earth Answer: h= i Not to scale (105) km
Let's assume that the planet was originally orbiting around something with the mass of our Sun (and thus the mass of the planet is negligible). Now we will examine the case where the planet orbits a star with 8 times the mass of our Sun, but we will say that the dates listed in the diagram above are still accurate for indicating the planet's position as it orbits the new star. What is ratio of the size of the semimajor axis of the planet in this case compared to the original (aka how many times larger {ratio greater than 1} or smaller {ratio less than 1} is the new semimajor axis than the old one)?
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.
PLEASE help me with the two questions. These are the only two I need help with and this is my last question until November. Please solve number #7 from the information in 6, and please solve question #9 from the information in number 8. THANK YOU PLEASE HELP!!
The unit of gravitational field strength g is newtons per kilogram. Explain how the unit of gravitational field strength relates to the unit of force.
Kepler's 3rd law is given as p2 = a3. If the orbital period of a space telescope at the second Sun-Earth Lagrange point (L2) is 1 year, is its orbit a violation of Kepler's 3rd law?
Please help me solve this problem. i got it wrong the first time. circle the answer please, thank you.
Many people mistakenly believe that the astronauts who orbit Earth are "above gravity." Earth's mass is 6×1024kg, and its radius is 6.38×106m(6380 kmkm). Use the inverse-square law to find a height above Earth's surface at that the force of gravity on a shuttle is about 96 %% that at Earth's surface.
Please answer part D and circle answer.
