PLEASE MARK AS A BRAINLISTTTTTTT

Answer 2

Answer:

Scaler Quantities:

The physical quantities which are completely specified by their magnitude or size alone are called scalar quantities. Examples: Length, mass, volume, work, energy and power. A Stella can be completely described by a number and a unit. For example, the mass of a man is 65 kg and the distance of my college is 20 km from my residence.

Vector Quantities:

The physical quantities which have both magnitude as well as direction are called vector quantities. Examples: Velocity, momentum, electric field, magnetic field, angular momentum, torque and impulse. A vector quantity is completely specified by the direction along with the magnitude and unit. For example, the velocity of my car is 50 kilometre per hour towards west direction.
