Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of birth. The only known force a planet exerts on Earth is gravitational.
(a) Calculate the magnitude of the gravitational force exerted on a 3.70-kg baby by a 100-kg father 0.221 m away at birth (assisting so he is close). N(b) Calculate the magnitude of the force on the baby due to Jupiter if it is at its closest to the Earth, some 6.29 1011 m away, showing it to be comparable to that of the father. The mass of Jupiter is about 1.90 1027 kg. Other objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.) N
(a) Find the magnitude of the gravitational force (in N) between a planet with mass 6.25 x 1044 kg and its moon, with mass 2.80 x 1042 kg, if the average distance between
their centers is 2.60 x 10 m.
(b) What is the moon's acceleration (in m/s) toward the planet? (Enter the magnitude.)
m/s2
(c) What is the planet's acceleration (in m/s) toward the moon? (Enter the magnitude.)
m/s2
In March 1999 the Mars Global Surveyor (GS) entered its final orbit about Mars, sending
data back to Earth. Assume a circular orbit with a period of 1.18 × 10² minutes and
orbital speed of 3.40 × 10³ m/s. The mass of the GS is 930 kg and the radius of Mars is
3.43 x 10°km.
(a) Calculate the distance between Mars surface and GS.
(b) Calculate the mass of Mars and weight of the GS on Mars surface.
(c) Calculate the total mechanical energy of the GS in this orbit.

- For many years, astronomer Percival Lowell searched for a Planet X that might explain some of the perturbations observed in the orbit of Uranus. These perturbations were later explained when the masses of the outer planets and planetoids, particularly Neptune, became better measured (Voyager 2). At the time, however, Lowell had proposed the existence of a Planet X that orbited the Sun with a mean distance of 43 AU. With what period would this Planet X orbit the Sun?arrow_forwardThe gravitational force exerted on an astronaut on the Earths surface is 650 N directed downward. When she is in the space station in orbit around the Earth, is the gravitational force on her (a) larger, (b) exactly the same, (c) smaller, (d) nearly but not exactly zero, or (e) exactly zero?arrow_forward(a) Find the magnitude of the gravitational force between a planet with mass 7.50 1024 kg and its moon, with mass 2.70 1022 kg, if the average distance between their centers is 2.80 108 m. (b) What is the acceleration of the moon towards the planet? (c) What is the acceleration of the planet towards the moon?arrow_forward
- How far from the center of the Sun would the net gravitational force of Earth and the Sun on a spaceship be zero?arrow_forwardIn the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (m1m2) . While all scientific conjectures must be experimentally verified, can you provided arguments as to why this must be? (You may wish to consider simple examples in which any other form would lead to contradictory results.)arrow_forwardA 200-kg object and a 500-kg object are separated by 4.00 m. (a) Find the net gravitational force exerted by these objects on a 50.0-kg object placed midway between them. (b) At what position (other than an infinitely remote one) can the 50.0-kg object be placed so as to experience a net force of zero from the other two objects?arrow_forward
- The mass of a particle is 15 kg. (a) What is its weight on Earth? (b) What is its weight on the Moon? (c) What is its mass on the Moon? (d) What is its weight in outer space far from any celestial body? (e) What is its mass at this point?arrow_forwardThe Sun has a mass of approximately 1.99 1030 kg. a. Given that the Earth is on average about 1.50 1011 m from the Sun, what is the magnitude of the Suns gravitational field at this distance? b. Sketch the magnitude of the gravitational field due to the Sun as a function of distance from the Sun. Indicate the Earths position on your graph. Assume the radius of the Sun is 7.00 108 m and begin the graph there. c. Given that the mass of the Earth is 5.97 1024 kg, what is the magnitude of the gravitational force on the Earth due to the Sun?arrow_forwardMiniature black holes. Left over from the big-bang beginning of the universe, tiny black holes might still wander through the universe. If one with a mass of 2 × 1011 kg (and a radius of only 4 × 10-16 m) reached Earth, at what distance from your head would its gravitational pull on you match that of Earth's? Assume free-fall acceleration ag=9.83 m/s2.arrow_forward
