If a 50 kg object is at a location 25,600 km from Earth’s center, what is the gravitational force exerted by the object on Earth? In what direction does that force act?

Approximately toward the center of the object.

Step-by-step explanation:

Look up the gravitational constant and the mass of the earth:

.

.

Convert the unit of distance to standard units:

.

Consider two spherical objects with mass and . Let denote the distance between the centers of the two objects. By Newton's Law of Universal Gravitation, the size of the gravitational force between these two objects would be:

.

Thus, the size of the gravitational force between this object and the earth would be:

.

Since gravitational force is attractive, the object in this question would attract the earth through the gravitational force. Thus, this force would point towards the center of this object.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

this is not the answer this is just a question. is this middle school math?
