Question

The orbit of Halley's Comet can be modeled by the polar equation:

1.07 1.97cos

where distances are measured in astronomical units (AU), and the sun is at the origin. Using Kepler's second law, where is the comet moving fastest? Slowest?

    A. The Sun travels in a circular orbit at a velocity of 220 km/second at a distance of 8.0 kiloparsecs from the center of the Galaxy (note that these numbers are slightly different from those in your book). Calculate the number of years it takes the Sun to complete an orbit (i.e., the circumference of a circle with an 8.0 kiloparsec radius) around the center of the Galaxy. (There are 3.1 x 1013 kilometers/parsec and 3.2 x 107 seconds/year.) B....

    PLEASE HELP TO ANSWER THIS LAB ACTIVITY Activity 3: Kepler's Second Law: Objects in elliptical orbits sweep oul equal areas in'equal times. This implies that the orbital speed of a planet around the sun is not uniform - it moves farthest away (known as APHELION). In this section we will calculate the difference in this fastest at the point closest to the sun (known as the PERIHELION) and slowest at the point speed using Pluto as an example. Pluto's orbit...

    Now M is the sum of the two masses in units of the solar mass .e. the mass of our Sun), while a is still in AU and P in years. An important application of Newton's generalization of Kepler's third law is being able to dete mine mass of a central body based on the motion of a satellite around that body. If the satellite is much less massive than the body it's orbiting, then M is essentially equal to...

I need to know each steps reasons. 5) (Kepler's Problem) Suppose that a particle is moving in three dimensions under the influence of the force k F=- where k is a positive constant. (a) Find the torque acting on the particle with respect to the origin. Is angular momentum conserved? Show that the magnitude of the angular momentum is given by l = mr2ė. (b) Using Newton's second law, show that the momentum of the particle is...

    Question 7 (0.5 points) What causes the Moon to move about 12° across the sky from one night to the next (at the same time of night, of course)? O Because the Earth is turning on its axis. O Because the Moon is moving in its orbit. The Sun has also moved 15° across the sky and gravitationally pulls the Moon with it. The celestial sphere the Moon is attached to has moved 15°. O It is an optical illusion....

    Can someone help me with this question and show all work 1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...

    I would really appreciate it if someone can help me with the whole question. thank you. You may be familiar with Newton's Second Law of Motion, SF = mā. In English, this equation says: The sum, or net, (S) of the forces (F) acting upon an object equals (=) the mass (m) of the object multiplied by the object's acceleration (ā). Even if you are familiar with this famous equation, did you notice the arrows above F and a before?...
