Two masses are in space far away from any star or planet. Mass 1 is 6 x 103 kg and mass 2 is 30 kg. The magnitude of the gravitational force between is .9 Newtons. If mass 2 is orbiting in a circular orbit around mass 1, what is its period of orbit in seconds? Assume mass 1 is not moving at all.
Two masses are in space far away from any star or planet. Mass 1 is 3 x 105 kg and mass 2 is 14 kg. The magnitude of the gravitational force between is 1.6 Newtons. If mass 2 is orbiting in a circular orbit around mass 1, what is its period of orbit in seconds? Assume mass 1 is not moving at all.
7. Planet A and planet B orbit around the same star. Planet A is thre times as far away from the star as planet B is. We can write the previous statement as a ratio: TA/TB 3, where r stands for the planet's distance to the star. What is the ratio of the period of planet A around the star to the period of planet B? In other words, labeling period as T, what is TA/TB? Give your answer with...
1. Which object (planet or star) takes a greater amount of time to complete one orbit? Explain. a. If the extrasolar planet is orbiting counterclockwise, what direction does the star orbit, clockwise or counterclockwise? b. Which letter, A, B, or C indicates the center of mass of the system? c. At a certain instant of time, how does the direction the extrasolar planet is orbiting compare to the direction the star is orbiting? d. In Figure...
The drawing shows three particles far away from any other objects and located on a straight line. The masses of these particles are m_4 = 363 kg, and m_c = 154 kg. Fend the magnitude and direction of the net gravitational force acting on each of the three particles (let the direction to the right be positive) particle A N particle A N particle A N A space traveler weighs 560 N on earth, what will the traveler weigh on...
A planet of mass m=2.95×1024 kg is orbiting in a circular path a star of mass M=1.75×1029 kg . The radius of the orbit is R=6.25×107 km . What is the orbital period (in Earth days) of the planet Tplanet ?
A large asteroid of mass 60900kg is at rest far away from any planets or stars. a smaller asteroid of mass 8.0 x 10^2 kg, is in circular orbit about the first at a distance of 366 meters as a result of their mutual gravitational attraction. What is the speed of the second asteroid? Now suppose that the first and second asteroids carry charges of +2.68c and -2.68c. How fast would the second asteroid have to be moving in order...
2. A new Earth-like planet is found orbiting a distant star with a circular orbit. The it takes 1.3 Earth years for the planet to make a full circle around it's star. The star has a radius 5 x 1011m. The altitude of the planet's orbit is 8 x 105 km. Find the mass of the star that the new planet is orbiting.
A large asteroid of mass 71700 kg71700 kg is at rest far away from any planets or stars. A much smaller asteroid, of mass 830 kg,830 kg, is in a circular orbit about the large asteroid at a distance of 256 m256 m as a result of their mutual gravitational attraction. What is the speed ?2v2 of the second asteroid? ?2 m/sm/s Now suppose that the first and second asteroids carry charges of +1.68 C+1.68 C and −1.68 C,−1.68 C,...
Problem 1 Planetary Orbits Consider the two-body problem for a planet-star system. The planet, of mass m, is initially in a circular orbit of radius r and angular speed w about the star, of mass M. (i) What is the gravitational potential energy of the system, U? What is the kinetic energy of the planet, K? What is the total energy of the system, E = K +U? (ii) The star suddenly loses half of its mass, M + M/2....
