✴Define Vector.
✴Define Velocity.​

Answer 1

Answer:

Vectors are used in science to describe anything that has both a direction and a magnitude. They are usually drawn as pointed arrows, the length of which represents the vector's magnitude. ... The billiard ball's momentum is also a vectorial quantity, because momentum is equal to mass times velocity.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. ... Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

Answer 2

Answer:

1) A vector is any vehicle, often a virus or a plasmid that is used to ferry a desired DNA sequence into a host cell as part of a molecular cloning procedure. Depending on the purpose of the cloning procedure, the vector may assist in multiplying, isolating, or expressing the foreign DNA insert.

Explanation:

2) Velocity is the speed at which something moves in a particular direction. the velocities at which the stars orbit.
