Class 11 Maths NCERT Solutions Chapter 9: Sequences & Series Ex – 9.1 Question 1: Write the first five terms of the sequence whose nth term is an = n (n + 2). Ans: an = n(n +2) Substituting n = 1, 2, 3, 4 and 5, we obtain a1 = 1 (1 + 2) = 3, […]
Sexual reproduction is a fundamental biological process through which most living organisms produce offspring. Unlike asexual reproduction, which involves a single parent, sexual reproduction requires the fusion of male and female gametes. This process results in the creation of genetically diverse offspring, playing a critical role in the evolution and survival of species. In this

What is Equilibrium? Equilibrium is a state where opposing forces or processes are balanced, resulting in no net change over time. This fundamental concept appears in: Chemistry (reaction balance) Physics (mechanical stability) Economics (market prices) Biology (homeostasis) I. Chemical Equilibrium Dynamic Balance in Reactions When forward/reverse reaction rates equalize, concentrations stabilize: aA+bB⇌cC+dDaA+bB⇌cC+dD Key Characteristics: Rates: $Rate_{forward} = Rate_{reverse}$ Constant
Understanding mean median mode is essential for anyone studying mathematics, statistics, data science, economics, or social sciences. These three terms represent the measures of central tendency, which describe the center or average of a data set. Whether you’re analysing test scores, salaries, survey results, or experimental data, these tools help simplify and interpret numerical information
