Is Colour change a physical or chemical property? Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is […]
Why do electrons have spin?
Why do electrons have spin? Because electrons of the same spin cancel each other out, the one unpaired electron in the atom will determine the spin. There is a high likelihood for either spin due to the large number of electrons, so when it went through the magnetic field it split into two beams. What […]
What transverse wave has the shortest wavelength?
What transverse wave has the shortest wavelength? violet light Are light waves transverse? Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse […]
Whats a rhizome look like?
Whats a rhizome look like? Technically, a rhizome is a stem that grows underground. It usually grows horizontally, just below the soil’s surface. This means a patch of what looks like several individual plants grouped near each other may actually all be shoots of the same plant, put up by the same rhizome. How do […]
What are the 5 different types of reactions?
What are the 5 different types of reactions? The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. What are 10 indicators of a chemical change? Bubbles of gas appear. Gas-producing reactions run to completion when the gas can leave the reaction mixture. A precipitate forms. A color change occurs. The […]
What is the ratio of calcium to fluoride ions?
What is the principle of DC generator *?
What is the principle of DC generator *? DC generator operates on the principle of the dynamically induced electromagnetic force. When a conductor is placed in a varying magnetic field, an electromotive force gets induced within the conductor. This induced e.m.f magnitude is measured using the equation of the electromotive force of a generator. What […]
What are the applications of soft and hard magnetic materials?
What are the applications of soft and hard magnetic materials? They are used in electrical rotating machine, electromagnet, electrical machine and transformer. It is used in communication equipment such as audio transformer, recording heads and magnetic modulators because of high initial permeability in feeble fields. They also possess low hysteresis and eddy current losses. Which […]
Do you really need noise Cancelling headphones?
Do you really need noise Cancelling headphones? Are noise-cancelling headphones worth it? Yes. If you wish to protect your hearing, reduce environmental distractions, and enjoy a better audio experience, then this technology will surprise you with its impactful results. Is Noise Cancelling safe? So, Is Noise-Canceling Safe? The short answer is, yes. Noise-canceling headphones, on […]
When can displacement be equal to distance?
When can displacement be equal to distance? Answer: When an object moves in a straight line in the fixed direction without coming back, it’s displacement and distance magnitude will always be equal. What is the symbol for hours and minutes? While the unit s , seconds is an SI standard, the symbols h for hours […]
