Radioactivity

Posted on 25/01/2018 by myrank

Radioactivity An atom is made up of three fundamental subatomic particles protons, neutrons and electrons. Out of these three particles, protons and neutrons located at the centre of the atom as a hard and dense part known as nucleus. The rest of the part of atom contains negatively charged particles called as electron which balance out the Read more about Radioactivity[…]

Differentiation by Substitution Methods

Posted on 25/01/2018 by myrank

Differentiation by Substitution Methods Substitution is useful to reduce the function into simple form. For problems involving inverse trigonometric functions, first try for a suitable substitution to simplify it and then differentiate it. If no such substitution is found, then differentiate directly. Some standard substitutions are given below. S.No Expressions Substitutions 1 x = atanθ Read more about Differentiation by Substitution Methods[…]

Derivative of a Function (Chain Rule) and Composite Function Derivative of a Function (Chain Rule): If y is a differentiable function of t and t is a differentiable function of x i.e., y = f(t) and t = g(x) then . Similarly, if y = f(u ), where u = g(v) and v = h(x) then Read more about Derivative of a Function (Chain Rule) and Composite Function[…]

Conditional Probability

Conditional Probability The probability of B under the assumption that A takes place. It is denoted by P(B/A) and is called the conditional probability of B given that A takes place Sometimes the probability of a given event depends on the occurrence or non-occurrence of some other event. Suppose A and B are two events in a Read more about Conditional Probability[…]

Photo Electric Effect

Posted on 21/01/201821/01/2018 by myrank

Photo Electric Effect Photoelectric effect or photoelectric emission is a phenomenon where electrons are ejected from the surface of a metal upon shining light on it. Energy which is contained within the light of incidence is getting absorbed by electron particles within the metal which escape the metallic surface given enough energy. The photoelectric effect Read more about Photo Electric Effect[…]

Limitations of Ohm’s Law

Posted on 20/01/201820/01/2018 by myrank

Limitations of Ohm’s Law In the year 1820 a French physicist, Andre Ampere made many discoveries on the nature of electricity. While a German physicist, Georg Ohm showed that the flow of an electric current through a wire depended on its ‘resistance’ and the potential difference between its ends. Ohm’s law is not a fundamental Read more about Limitations of Ohm’s Law[…]
