E12. Two 600-kg masses (1323 lb) are separated by a distance of 64 m. Using Newton’s law of gravitation, find the magnitude of the gravitational force exerted by one mass on the other.

You encounter a strange cosmic string in outer space.  The string extends along the x axis from x = 0 m to x = 4.6 x 104 m.  You are located at x = -5.4 x 104 m.  You experience a gravitational field equal to 9.6 x 10-6 N/kg at this location.  Assuming the string has a constant linear mass density, calculate this linear mass density, in units of 105kg/m.  Use G = 6.7 x 10-11 N m2/ kg2. (Please answer to the fourth decimal place - i.e 14.3225)

1. On a planet whose radius is 1.5 × 107 m, the acceleration due to gravity is 20 m/s². An astronaut with a mass of 60 kg is standing on its surface.

We all know the Earth exerts gravity on us, but other objects in the solar system also pull on us. In the following series of problems we will investigate how strong gravity is for a person standing on the surface of the Earth from various objects in the solar system. You can answer the following series of questions using Newton's Law of Gravity; use the units given and the Gravitational Constant, G = 6.67 ×10 -11 m 3 /kg/s 212: Some people claim that the location of Jupiter can have dramatic consequences on human events on Earth. For comparison to the last problem, what is the force of gravity due to a 100 kg person hugging a 60.0  kg ASTR 110 student. Assume the distance between the students is 0.3 meters.using the right formula: Fg = (G M1 M2 / d^2)

A 4.00 x 10^8 kg mass and 5.00 x 10^8 kg mass are separated by a distance of 2.0 km. What is the gravitational force of attraction between the masses?

Four small spheres each with a mass of m = 14 kg are attached to the corners of a square. The length of one side of the square is L = 8 meters. See figure below. Find the magnitude of the gravitational field due to these four point masses at the position P in the middle of the bottom leg of the square as shown. Use G = 6.673E-11 N m2/kg2.

You are completing a report for NASA on the mass and weight of various objects on different planets. What can you determine about the relationship between mass and gravity? What can you determine about the relationship between weight and gravity? Provide evidence to support your observations using the gravitational values below.Gravitational Values for Select Planets Mercury: 3.7 m/s ^ 2 Venus: 8.9 m/s ^ 2 Mars: 3.7 m/s ^ 2 Neptune: 11.0 m/s ^ 2

The gravitational force of attraction between any two point masses is attractive and the magnitude: Gm₂m₂ G = 6.67 x 10-11 N-m² kg² F= where G is the gravitation constant, m, and m₂ are the masses, and r is the distance between the masses. This is quite different from the force of gravity that we have been using, where weight = mg. 1. Acceleration due to gravity: a. Lett one mass be the Earth and the other mass m is let go just above the surface of the Earth. Calculate the value of the acceleration due to gravity using Newton's law of gravitation. The net effect of the Earth's gravity is the same as if the all the mass of the Earth were concentrated at its center. b. The F-22 Raptor fighter jet has a service ceiling of 12 miles or 20 km. Determine the acceleration due to gravity at this altitude. c. The International Space Station is in low Earth orbit at a height of 400 km above the surface of the Earth. Determine the acceleration due to gravity at this altitude. d. What is assumed…
