The gravitational force that earth exerts on an object is inversely proportional to the square of the distance between the center of the earth and the object. when bill is on the surface of earth, 4,000 miles from the center, the gravitational force is 600 newtons. what is the gravitational force (in newtons) that the earth exerts on him when he's standing on the moon, 240,000 miles from the center of the earth? express your answer as a fraction.

Step-by-step explanation:

Let d be the distance from Bill to the center of the Earth and f be the gravitational force that the Earth exerts on him. Since f is inversely proportional to , for some constant k. Since the force when Bill is on the surface of Earth is 600 Newtons, . Therefore, if we let x be the force that the Earth acts on Bill with when he is on the Moon,

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

the answer is c.
