I would think the answer would be c
Explanation:
Physical quantities are usually designated as either vector or scalar quantities.
There are several fundamental quantities know out there that makes definition of the world possible. Derived quantities are obtained from these fundamental quantities.
- A vector quantity expresses a quantity that shows both magnitude and direction.
- With a vector, you know the amount or quantity of measurement taken and the directional attribute.
- A scalar quantity is a quantity that shows magnitude but no direction.
- For example velocity is a vector and speed is a scalar. If a body moves at 10m/s due east, that is a vector.

Answer:
the one above the surface of earth
Explanation:
earth has gravity the ball of the moon would float away
Answer:
d. A projectile with a horizontal component of motion will have a constant horizontal velocity.
f. The horizontal velocity of a projectile is unaffected by the vertical velocity; these two components of motion are independent of each other.
g. The horizontal displacement of a projectile is dependent upon the time of flight and the initial horizontal velocity.
h. The final horizontal velocity of a projectile is always equal to the initial horizontal velocity.
Explanation:
When we are dealing with parabolic motion, the x-component of the velocity remains the same (hence, in the case of the horizontal component, the acceleration will always be zero), <u>while the y-component always change because it is affected by the acceleration due gravity that acts verticaly.</u>
On the other hand, the horizontal displacement 
of the projectile is mathematically expressed as:
Where:
is the projectile's horizontal component of the initial velocity
is the time the parabolic motion lasts
This means <u>the projectile's horizontal displacement is directly proportional to the horizontal component of the initial velocity and the total time the projectile describes the parabolic motion</u>.
Of course, all of this considerations are assuming this is an ideal parabolic path and there is no air resistance.
