Astrology makes much of the position of the planets at the moment of one’s birth. The only known force a planet exerts on Earth is gravitational.
Calculate the gravitational force exerted on a baby of mass 4.20 kg by a doctor with a mass of 100 kg if they are separated by a distance of 0.200 m.
Calculate the gravitational force exerted on a baby of mass 4.20 kg by the planet Jupiter. Use a value of kg for the mass of Jupiter and use a value of m for the separation between the planet and the baby.
Find the mass of the Sun. Use a value of km for the average distance between the centers of Earth and the Sun.
Find the orbital velocity of Earth’s solar system about the center of the Milky Way. Use a value of ly for the distance between the center of mass of Earth’s solar system and that of the Milky Way, solar masses for the mass of the Milky Way, and kg for the mass of the Sun.
