Q1. How can you define the Difference between a slope and a Gradient
Ans. 
A slope is the steepness of a surface while a gradient is the rate of change of a variable.
• Slope refers to the angle of inclination of a surface, while gradient refers to the change in elevation or value of a variable over a distance.

• Slope is measured in degrees or percentage, while gradient is measured in units of the variable per unit of distance.

• For example, the slope of a hill is 30 degrees, while the gradient of t...read more
