Let's go through each question one by one to understand the concepts involved:

Which of the following is a physical quantity that has both magnitude and direction?
A vector is a physical quantity that has both magnitude (size) and direction. Vectors are used to represent quantities such as displacement, velocity, and force. In contrast, a scalar is a quantity that only has magnitude and no direction, such as temperature and mass. The correct answer is:
A) Vector

Which of the following pairs include a vector quantity and a scalar quantity?
In physics, vector quantities have both magnitude and direction, while scalar quantities only have magnitude. Let's look at each option:

A) Work - Pressure: Both work and pressure are scalar quantities.
B) Power - Distance: Both power and distance are scalar quantities.
C) Force - Potential Energy: Force is a vector quantity because it has direction, while potential energy is a scalar quantity.
D) Velocity - Acceleration: Both velocity and acceleration are vector quantities.

The correct answer is:
C) Force - Potential Energy

The splitting of vectors into two components is called
When you break a vector into two or more vectors that are along the axes of a coordinate system, this process is called resolution of vectors . It is a technique used to simplify vector analysis by breaking a vector into its horizontal and vertical components. The correct answer is:
C) Resolution of vectors


These questions are fundamental to understanding vector and scalar quantities, which are essential concepts in physics, particularly when analyzing forces and motion.
