Answer:
Magnitude and direction.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;

Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
Hence, in free fall, the magnitude and direction of velocity of the object changes.
Answer:
0.5 eV
Explanation:
= Initial potential energy = 
= Final potential energy
= Initial width
= Final width = 
Energy of an electron in a one-dimensional trap is given by

From the equation we get

So,

The ground state energy will be 0.5 eV

The startling answer is:
The bacteria ate the agar and reproduced (made more bacteria). There are so many of them now that you can see the blob of them.
