Space vehicles apply action and reaction forces to blast off by using rockets to thrust down toward the ground. In reaction, the space vehicle is... View Article
An Adiabatic process is characterized by an increase in entropy if the process is irreversible and no change in entropy if they are reversible.... View Article
Destructive interference occurs when the maxima of the waves are 180 degrees out of phase. The amplitude of the resulting wave is zero. Read... View Article
Yes, we can have a neagtive emf. The negative sign implies that the electromotive force induced will be induced in order to oppose the cause.... View Article
Energy in a coil is stored in the form of magnetic energy. Assuming we have an electrical circuit containing a power source and a solenoid of... View Article
The moelcules at higher temperature have more energy and vibrate faster allowing sound waves to travel more quickly. The speed of sound at room... View Article
The centre of mass of a uniform rod is at the centre of the rod. Even the centre of gravity of a uniform rod also lies at the centre of the rod.... View Article
Freezing point depression refers to the lowering of the freezing point of solvents upon the addition of solutes. The depression in the freezing... View Article
Gibbs free energy is the energy associated with the chemical reaction that can do useful work. The Gibbs free energy equals the enthalpy minus... View Article
Electric susceptibility is the quantitative measure of the extent to which an electric field applied to a dielectric material causes polarization.... View Article
Equations of motion, in physics, are defined as equations that describe the behaviour of a physical system in terms of its motion as a function... View Article
The spacing between two bright fringes in the interference pattern produced by two-slit is given by the following formula: In the above... View Article
A wave is periodic disturbance in the medium through which it propagates. A water wave creates a periodic disturbance in water, similarly A... View Article
Absolute potential energy is defined as the amount of work that needs to be done to bring an object to its current location from a point of... View Article
