  Q1. A car accelerates uniformly from a velocity of 10 m/s to 30 m/s in 10 seconds. What is its acceleration? Hint: Use the formula for uniform acceleration:a=v−uta = \frac{v – u}{t}​ Step-by-Step Solution: Initial velocity: u=10 m/su = 10 \, \text{m/s} Final velocity: v=30 m/sv = 30 \, \text{m/s} Time: t=10 st = 10 \, \text{s}…

1. Introduction Coordinate Geometry is the branch of mathematics where we study the position of points on a plane using numbers called coordinates. The plane on which we locate points is called the Cartesian Plane or Coordinate Plane. 2. Cartesian System A Cartesian Plane consists of two mutually perpendicular lines: The point where these two…

Coordinate Geometry – Class 9 CBSE Mathematics 1. Introduction Coordinate geometry, also known as analytic geometry, studies the geometric properties of shapes using a coordinate system. It helps in locating points on a plane using coordinates. The plane is divided by two perpendicular lines: x-axis (horizontal) y-axis (vertical) Their intersection is called the origin (O),…

What is a Pie Chart? A Pie Chart is a circular graph that represents data as slices of a pie. Each slice shows a part of the whole, and the size of each slice is proportional to the quantity it represents. Key Features of a Pie Chart Steps to Create a Pie Chart Example Imagine…
