The device that can be used for precise measurement of wavelength is a Michelson Interferometer.
A Michelson interferometer uses the interference of light waves to measure very small distances, including wavelengths, with high accuracy.
An alkyl group is formed by removing a hydrogen atom from an alkane, and since the hydrogen atom is removed with one bonding electron, the resulting group has an unpaired electron, making it a radical.
Fluorine, being the smallest halogen, has the weakest intermolecular forces and therefore the lowest boiling point.
The statement "The mechanical energy spent by the external agency is converted into electrical energy stored in the coil" relates to Lenz's law.
Resistivity after cutting a wire in half:
Resistivity 𝜌 is a material property, independent of shape, size, or length.
When a wire is cut, resistance changes, but resistivity remains the same.
The diameter of an atom is in the order of 0.2 nanometers (nm), or 200 picometers (pm), which is equivalent to 2 x 10^-10 meters.
A fatty acid is a carboxylic acid with a long aliphatic chain.
Phthalic acid has a benzene ring structure, which is not characteristic of fatty acids
The muscle type that is NOT found in the human body is Cartilage muscle.
While cartilage is a strong connective tissue, it is not considered a muscle tissue
The three main muscle types are:
Avogadro's number represents the specific quantity of particles (atoms, molecules, ions, or electrons) contained in one mole of a substance.
It's a large constant value approximately equal to 6.022 x 10^23.
COVID-19 is a viral disease caused by the SARS-CoV-2 virus.
It primarily affects the respiratory system, leading to symptoms like cough, fever, shortness of breath, and in severe cases, pneumonia.
