Science > Physics > Wave Motion > Wave Motion The motion that repeats itself after fixed intervals of time is called periodic motion. We know that oscillatory motion is a type of periodic motion. Oscillatory motion is defined as the to and fro motion of an object from its mean position. Examples: oscillation of simple […]
Science > Physics > Stationary Waves > Numerical Problems Vibration of String Set-03 In this article, we shall study to solve problems to calculate fundamental frequency of vibration of string and its higher frequencies. Example 01: A stretched wire of length one metre gives 3 beats per second with a tuning fork. If the length […]
Science > Physics > Stationary Waves > Numerical Problems Vibration of String Set-02 In this article, we shall study to solve problems to calculate fundamental frequency of vibration of string and its higher frequencies. Example 01: A stretched wire emits a fundamental note of 256 Hz. Keeping the stretching force constant and reducing the length […]
Science > Physics > Stationary Waves > Numerical Problems Vibration of String Set-01 In this article, we shall study to solve problems to calculate fundamental frequency of vibration of string and its higher frequencies. Important Formulae: For vibrating string pth overtone is (p + 1)th harmonic Frequency of qth harmonic = q x n Frequency […]
Science > Physics > Refraction of Light > Emission and Absorption Spectra A spectrum is a pattern which gives the wavelengths of radiation emitted (or absorbed) by a substance. The spectra in the visible region are divided into two groups. Emission spectra and absorption spectra. We use a spectrometer to study a spectrum. Light from […]
Science > Physics > Electromagnetic Induction > Numerical Problems on Electromagnetic Induction In this article, we shall learn to solve numerical problems to find e.m.f. induced, change in flux, and change in magnetic induction. Example 01: A circular coil having 1000 insulated turns each of area 1.274 m2 is kept in a uniform magnetic field […]
Science > Chemistry > Molecule and Molecular Mass > Calculation of Number of Moles and Molecules In this article, we shall solve problems to calculate number of moles and number of molecules and atoms present in given quantity of a substance. Example 01: 3.49 g of ammonia at STP occupies 4.48 dm3. Calculate molar mass […]
“Res ipsa loquitur” is a Latin phrase that means, “the thing speaks for itself” and pertains to obvious cases of negligence. Under the common law of negligence, the res ipsa loquitur doctrine indicates that a breach of a party’s duty of care may be inferred from the events that occurred. In other words, the negligence is so […]
Law > Medical Jurisprudence > Law and Medicine > Medical Negligence A tort is a residuary civil wrong. Duties in tort are fixed by the law and such duties are owed in rem or to the people at large generally. Such wrongs can be remedied by filing for unliquidated damages. Negligence is a tort. A […]
Law > Medical Jurisprudence > Law and Medicine > Right to Health in the Constitution Health is a vital indicator of human development and human development is the basic ingredient of economic and social development. According to the World Health Organization (WHO), health is a state of complete physical, mental and social well-being and not merely the […]
