Heat and work are forms of energy that are in motion. They exist only when there is a change in the state of system and surroundings. In other... View Article
Reactions that have negative delta G release free energy and are known as an exergonic reaction. A negative ∆G indicates that the reactants, or... View Article
We know that the speed of sound in air is 343 m/s, and from the given question we know that the frequency of the sound wave is 1 Hz. Employing... View Article
Normally, two types of stresses are induced in a shaft. They are: 1) Torsional stresses due to the transmission of torque and, 2) Bending... View Article
Light intensity or luminous intensity in physics is the amount of light falling on a surface over any given square foot or square meter. Light... View Article
PCM stands for Pulse Code Modulation. It is the process of converting analog signal into a digital signal using three basic functions which are... View Article
The Gibbs free energy can either increase or decrease when the temperature increases. This condition depends on the change in the entropy. The... View Article
It is false to assume that there is no gravity in space, in fact, a small amount of gravity is found everywhere in space. After all, gravity is... View Article
Elements such as helium and hydrogen that have small nuclei release plenty of energy when they fuse together. When the fusion process involves... View Article
Electrostatics has proven useful in many areas. Some of these applications are listed below: Robert Van de Graaff first built the Van de... View Article
The magnetic field inside the solenoid is proportional to the applied current and the number of turns per unit length. There is no dependence on... View Article
Maxwell predicted that magnetic and electric fields travel in the form of waves and these waves move at the speed of light. This led Maxwell to... View Article
The three main principles of the kinetic theory are: No energy is gained or lost during the collision between molecules. Molecules take up a... View Article
The heat as it flows brings along some entropy which must be disposed of before the cycle can start. To get rid of the entropy, every heat engine... View Article
The gas laws apply only to ideal gases. Ideal gases are gases whose behaviour is interpretable. Some characteristics of ideal gases are: They... View Article
Capacitors in a DC circuit gradually charge until the charging voltage of the capacitor becomes equal to the supply voltage. The capacitor... View Article
Superposition theorem states that the response across any element in a linear bilateral network having more than one source is the sum of the... View Article
The direction of the conventional current is from the positive terminal to the negative terminal. The actual flow of current is due to the... View Article
The molecular orbitals of the molecule depend on the total number of the atomic orbitals that make them. Let us consider the example of the... View Article
