Answer 1

${\huge{\pink{\underline{\underline{\red{\mathbb{\bigstar{\pink{ᎯᏁᏕᏯᎬᏒ}}}}}}}}}$

The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

Answer 2

It has both magnitude and direction, hence, it's a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
