What will be the appearance of a TLC plate if a solvent of too low polarity is used for development? If the solvent is of too low a polarity the components will not move enough, and again separation will not occur (Rf’s will be too small). Note that the spotting solvent is simply used as […]
What is better 50Hz or 60Hz?
What is better 50Hz or 60Hz? The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is simply that 60 Hz is 20% higher in frequency. Lower the frequency, speed of induction motor and generator will be lower. For example with 50 Hz, generator will be running at 3,000 RPM against 3,600 RPM with […]

What is electricity kid friendly definition?
What is electricity kid friendly definition? Electricity is the flow of tiny particles called electrons and protons. It can also mean the energy you get when electrons flow from place to place. Lightning is nothing but a large number of electrons flowing through air all at once, releasing a huge amount of energy. What is […]
Is breaking bonds positive or negative?
Is breaking bonds positive or negative? Generally, a positive change in enthalpy is required to break a bond, while a negative change in enthalpy is accompanied by the formation of a bond. In other words, breaking a bond is an endothermic process, while the formation of bonds is exothermic. How do you break bonds? It […]
What is considered high viscosity?
What is considered high viscosity? Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. Does water have a high viscosity? Viscosity describes a fluid’s […]
How do you make an electric motor spin faster?
Is Eigenstate an eigenfunction?
Is Eigenstate an eigenfunction? is that eigenstate is (physics) a dynamic quantum mechanical state whose wave function is an eigenvector that corresponds to a physical quantity while eigenfunction is (mathematics) a function \phi such that, for a given linear operator d , d\phi=\lambda\phi for some scalar \lambda (called an eigenvalue). How do you know if […]
What day has 12 hours of daylight?
What day has 12 hours of daylight? September Equinox Are days exactly 24 hours? On Earth, a solar day is around 24 hours. However, Earth’s orbit is elliptical, meaning it’s not a perfect circle. That means some solar days on Earth are a few minutes longer than 24 hours and some are a few minutes […]
What is the main function of the intervertebral discs?
What is the main function of the intervertebral discs? Functions of the Disc The primary function of the disc is to join the vertebrae and allow movement between them. The other functions are typical of the erect spine: a shock absorber; a load distributor; and a separator of the posterior facets to maintain the size […]
