Stability refers to the ability of a system to return to a steady state after being disturbed.
Stability is crucial in various fields such as engineering, economics, and ecology.
In engineering, stability is important for structures to withstand external forces without collapsing.
In economics, stable markets are characterized by consistent prices and low volatility.
In ecology, stable ecosystems have balanced populations ...
Electrolytic capacitors store higher amount of energy.
Electrolytic capacitors have higher energy storage capacity compared to other types of capacitors.
They are commonly used in power supply circuits and audio amplifiers.
Examples of electrolytic capacitors include aluminum electrolytic capacitors and tantalum capacitors.
Molecules are held together in crystals by intermolecular forces.
Intermolecular forces, such as hydrogen bonding, electrostatic interactions, and van der Waals forces, hold molecules together in crystals.
These forces are responsible for the regular arrangement of molecules in a crystal lattice.
Examples of crystals held together by intermolecular forces include salt (sodium chloride) and quartz.
The strength and type of ...
C-O bond length is minimum in carbonyl compounds.
Carbonyl compounds have a double bond between carbon and oxygen.

I was interviewed in May 2021.
The minimum temperature of any substance that we could reach and use for practical purposes is absolute zero, which is -273.15 degrees Celsius or 0 Kelvin.
The minimum temperature is known as absolute zero.
It is the lowest possible temperature that can be reached.
At absolute zero, all molecular motion ceases.
Practical applications include cryogenics and superconductivity.
Examples of practical uses are in medical imaging

Wind tunnels are used to study the effects of air on objects. Materials and their properties play a crucial role in wind tunnel experiments.
Wind tunnels are used to simulate the flow of air around objects, allowing scientists to study aerodynamics.
Different materials have different properties that can affect the results of wind tunnel experiments.
Materials with low drag coefficients, such as smooth metals, are often us...
Modes of vibrations of beans refer to the different ways in which beans can oscillate or vibrate.
Beans can vibrate in different modes depending on their shape, size, and material properties.
Some common modes of vibrations in beans include bending, twisting, and radial vibrations.
The mode of vibration affects the frequency, amplitude, and pattern of the bean's oscillation.
Understanding the modes of vibrations in beans c...

There are three laws of thermodynamics. Each law has specific applications. dB Amp is not related to thermodynamics.
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed.
The second law of thermodynamics states that the entropy of an isolated system always increases over time.
The third law of thermodynamics states...
Spark plug ignites fuel-air mixture in IC engines. DTSI improves combustion efficiency. 2-stroke and 4-stroke engines differ in number of strokes per cycle.
Spark plug ignites the fuel-air mixture in the combustion chamber
DTSI (Digital Twin Spark Ignition) is a technology used to improve combustion efficiency by using two spark plugs
2-stroke engines complete one power stroke in two strokes of the piston, while 4-stroke ...
Humidity ratio is measured using two types of instruments: psychrometers and hygrometers.
Psychrometers measure humidity ratio by comparing the readings of two thermometers: a dry-bulb and a wet-bulb thermometer.
Hygrometers measure humidity ratio using various principles such as electrical resistance, capacitance, or condensation.
A 1 ton refrigerator refers to the cooling capacity of the refrigerator, which is equivalen...
