Your friend tells you that if you double the distance of a spacecraft from the planet, the gravitational force is one half as strong. Do you think this is correct?

No. When the distance is doubled, the gravitational force is 1/4 times as strong, therefore, the correct answer is she is not correct

Explanation:

The gravitational force is given as follows;

Where;

m₁, and m₂ are the masses sharing the gravitational field

G = The universal gravitational constant

r = The distance between the centers of the two masses

Therefore, when the new distance, R = 2 × r, we get;

Therefore, when the distance is doubled, the gravitational force is one fourth as strong, therefore, she is not correct.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
