A moon of mass m orbits around a non-rotating planet of mass M with orbital angular velocity . The moon also rotates about its own axis with angular velocity .
1. A moon of mass \(m\) orbits around a non-rotating planet of mass \(M\) with orbital angular velocity \(\Omega\). The moon also rotates about its own axis with angular velocity \(\omega\). The axis of rotation of the moon is perpendicular to the plane of the orbit. Let \(I\) be the moment of inertia of the moon about its own axis. You can assume \(m<<M\)so that the center ofmass of the system is at the center of the planet.(a) What is...

After landing on the planet, you set off, walking always straight ahead, and find yourself returning to your spacecraft from the opposite side after completing a lap of 26.0 km. You hold a hammer and a falcon feather at a height of 1.76 m, release them, and observe that they fall together to the surface in 29.7 s. Determine the mass of the planet. Part 1...

23. A spacecraft is in orbit around the Earth, where if feels a gravitational force of magnitude F. At that moment, it is located a distance L away from the center of the Earth. Later, the spacecraft leaves orbit and travels away from the Earth to visit an asteroid which is passing by. When it reaches the asteroid, it is a distance 40L away from the center of the Earth.

1 points SPreCalc7112.065.MI. My Notes Ask Your Teacher The planets move around the sun in elliptical orbits with the sun at one focus. The point in the orbit at which the planet is closest to the sun is called perihelion, and the point at which it is farthest is called aphelion. These points are the vertices of the orbit. A planet's distance from the sun is 207,000,000 km at perihelion and 249,000,000 km at aphelion. Find an equation for the...

A gray-body fly with long wings is subjected to a test cross. The F1 progeny of this test cross: Will only be of two phenotypes if the test cross fly is homozygous for both traits. Will only be of two phenotypes if the gray-bodied/long-winged fly is homozygous for both traits. Will be of four genotypes if the gray-bodies/long-winged fly is heterozygous for both traits. Will be of four genotypes if the test-cross fly is heterozygous for both traits. None of...
