0.58, 0.58, 0.58

Explanation:

Given vector, a = (7.9, 7.9, 7.9)

Unit Vector, $\overline{a} = \frac{a}{|a|}$

The magnitude $|a| = \sqrt{(7.9)^{2} + (7.9)^{2} + (7.9)^{2}}$

$|a| = \sqrt{62.41 +62.41 +62.41}$

$|a| = \sqrt{187.23}$

|a| = 13.68

$\overline{a} = \frac{(7.9, 7.9, 7.9)}{\sqrt{187.23}}$

$\overline{a} = (0.58, 0.58, 0.58)$

The unit vector is (0.58, 0.58, 0.58)

Explanation:

Gravitational force keeps it attracted to the Earth, and centripetal force keeps it moving in a circle. ... Explain how Newton's third law and his law of universal gravitation are connected. His third law states that every force has an equal opposite force attracted to it, and that force is caused by gravity.
