1. The time period of a simple pendulum is T = 2π √ (l/g) => T α √l or T α 1/√g T α √ (l/g) Using these relations. We may conclude => The graph between T2 and l is a straight line. => The graph between T and l is a parabola. => The Read more about Tips & Tricks of SHM[…]
Puzzle 1: Which letter replaces the question mark?Answer: F Explanation: Working in rows, from top to bottom, the sum of the numerical values of the letters in each row starts at 12, and increases by 2 as you go down each row.

Rule (I): Differentiation of a constant function is zero i.e., d/dx (c) = 0 Rule (II): Let f(x) be a differentiable function and let c be a constant. Then c.f(x) is also differentiable such that , This is the derivative of a constant times a function is the constant times the derivative of the function.

Concentrations of the solution can be expressed as 1. Molarity: No: of moles of solute present in one liter solution. Units: mol L¯¹ Ex: 0.5 M ethanol means 0.5 moles of ethanol dissolved in one liter. 2. Mass percentage (w/w) = Ex: a solution of 20% salt in water by mass means: 20g of salt + Read more about Concentrations of the Solution[…]

⇒ Generally matter expands on heating and contracts on cooling. In case of water, it expands on heating if its temperature is greater than 4°C. In the range 0°C to 4°C, water contracts on heating and expands on cooling, i.e. g is negative. This behaviour of water in the range from 0°C to 4°C is Read more about Anomalous Expansion of Water[…]

If y = f(x), then dy/dx the derivative of y with respect to x, is itself, in general or function of x and can be differentiated again. To fix up the idea, we shall call dy/dx as the first order derivative of y with respect to x and the derivative of dy/dx w.r.t. x as Read more about Higher Order Derivatives[…]
