Answer:
Scalar quantity
Vector quantity
Explanation:
A scalar quantity is a quantity that is fully described by magnitude alone. Examples include; mass, temperature etc
A vector quantity is described by both magnitude and direction. E.g force, weight etc
Explanation:
due to its shape st the bottom
The two satellites orbit around the same planet, so we can use Kepler's third law, which states that the ratio between the cube of the radius of the orbit and the orbital period is constant for the two satellites:

where

is the orbital radius of the first satellite

is the orbital radius of the second satellite

is the orbital period of the first satellite

is the orbital period of the second satellite
If we use the data of the problem and we re-arrange the equation, we can calculate the orbital period of the second satellite:
