- A massive black hole is believed to exist at the center of our galaxy (and most other spiral galaxies). Since the 1990s, astronomers have been tracking the motions of several dozen stars in rapid motion around the center. Their motions give a clue to the size of this black hole. a. One of these stars is believed to be in an approximately circular orbit with a radius of about 1.50 103 AU and a period of approximately 30 yr. Use these numbers to determine the mass of the black hole around which this star is orbiting, b. What is the speed of this star, and how does it compare with the speed of the Earth in its orbit? How does it compare with the speed of light?arrow_forwardAstronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.1011 solar masses. A star orbiting on the galaxy's periphery is about 6.0104 light years from its center. (a) What should the orbital period of that star be? (b) If its period is 6.0107 instead, what is the mass of the galaxy? Such calculations are used to imply the existence of "dark matter" in the universe and have indicated, for example, the existence of very massive black holes at the centers of some galaxies.arrow_forwardAstronomical observatrions of our Milky Way galaxy indicate that it has a mass of about 8.01011 solar masses.

(a) M (b) m (c) the density of the planet (d) R (e) the acceleration due to gravity on that planetarrow_forwardWhen Sedna was discovered in 2003, it was the most distant object known to orbit the Sun. Currently, it is moving toward the inner solar system. Its period is 10,500 years. Its perihelion distance is 75 AU. a. What is its semimajor axis in astronomical units? b. What is its aphelion distance?arrow_forwardTidal friction is slowing the rotation of the Earth. As a result, the orbit of the Moon is increasing in radius at a rate of approximately 4 cm/year. Assuming this to be a constant rate, how many years will pass before the radius of the Moon's orbit increases by 3.84106 m (1%)?arrow_forward
- In your own words, describe the difference between the terms gravitational force and gravitational field.arrow_forwardReview. A student proposes to study the gravitational force by suspending two 100.0-kg spherical objects at the lower ends of tables from the ceiling of a tall cathedral and measuring the deflection of the cables from the vertical. The 45.00-m-long cables are attached to the ceiling 1.000 m apart. The first object is suspended, and its position is carefully measured. The second object is suspended, and the two objects attract each other gravitationally. By what distance has the first objet I moved horizontally from its initial position due to the gravitational attraction to the other object? Suggestion: Keep in mind that this distance will be very small and make appropriate approximations.arrow_forwardA 42-inch Smart TV of mass 2.5 x 101 kg experiences a gravitational force when on the Earth's surface. A physicist estimates that Earth has a mass of 5.972 x 1024 kg and a diamete of 1.2742 x 10* km. а. State: i. The equation used to represent Newton's law of gravitation, and ii. The equation for the gravitational field strength, g, experienced by an object on the Earth's surface. b. By considering (i) and (ii), calculate the gravitational field strength g, for the TV at Earth's surface. The TV is moved further away from Earth's surface to a distance twice the radius of Earth. Will the effect of the gravitation field strength be the same on the TV? Explain your answer. с. d. Geostationary satellites are used in television transmission. A geostationary satellite of mass 4.45 x 103kg is used to transmi television programming to the TV on Earth. i. State the orbital period of the satellite. ii. Calculate the angular velocity of the satellite. iii. Calculate the distance between the center…arrow_forward
