Why we use collective model in nuclear physics?
When liquid drop and shell models fail to explain different phenomena like, electric quadrupole moment, magnetic dipole moment In addition to individual nucleons changing orbits to create excited states of the nucleus as described by the Shell Model, there are nuclear transitions that involve many (if not all) of the nucleons. Since these nucleons are acting together, their properties are called collective, and their transitions are described by a Collective Model of nuclear structure. High-mass nuclei have low-lying excited states that are described as vibrations or rotations of non spherical nuclei. Many of these collective properties are similar to those of a rotating or vibrating drop of liquid, and in its early development the Collective Model was called the Liquid-Drop Model. The first important application of the Liquid-Drop model was in the analysis of nuclear fission, in which a massive nucleus splits into two lower-mass fragments. The Liquid Drop Model calculates an energy barrier to fission as a sum of the repulsive Coulomb forces between the protons of the nucleus and the attractive surface tension of the skin of the "liquid drop" nucleus. If the barrier is low enough the nucleus might fission spontaneously. For higher barriers, it takes a nuclear reaction to induce fission. The figure above shows the energy levels of 238U. The quantum numbers, level spacings, and gamma ray transition probabilities identify these levels as rotational states of a non spherical nucleus. Nuclei showing collective properties are usually those with many valence nucleons, that is, those with proton or neutron numbers that are far from filled shells. As with the Shell Model, the Collective Model permits the calculation of spin-parity assignments and transition probabilities that are in good agreement with the measured properties of collective nuclei.
A drop of liquid precipitation that is 2 mm in diameter is?
rain
What does the word droplet mean?
A droplet is a very small drop of a liquid. It is typically used to describe tiny, spherical or nearly spherical particles of liquid. For example, raindrops are droplets of water falling from the sky, and when you put a drop of water on a surface,
If a liquid is thick and you drop an object in to it is the terminal velocity larger or smaller?
Smaller.
What property was discovered in millikans expirements?
the oil drop experiment postulated unit charges or electrons
The liquid drop model?
The mechanism of nuclear fission is best understood by noting that a massive nucleus behaves in many respects like a drop of liquid . According to this liquid drop model , the neutron absorbed by the 92U235 nucleus gives the nucleus extra energy (like heating a drop of water.
Does the pressure of a liquid depend on its density?
Density is an intrinsic property, and as such it does not depend on the size of the object. A drop of water will have a density of 1g/ml whether it is a big drop, or a very small drop.
What is saddle point in nuclear fission?
In the liquid drop model, excitation energy in a nucleus gives rides to modes of motion or oscillations. On a potential energy surface, the saddle point corresponds to the critical deformation of unstable equilibrium in the nucleus.
What is the uses of the liquid dropper?
it is used to drop very small amount of liquid.
What is the use of a liquid dropper?
it is used to drop very small amount of liquid.
What are the function of pipette in laboratory?
three main functions: to accurately measure a volume of a liquid to accurately measure the amount of volume of a liquid required to add into a another liquid for a specific results to apply a a liquid to another liquid drop by drop for maximum efficiency

Does the density of a liquid affect its droplet shape?
A drop is a drop.Example? A drop of water is exactly like a drop of melted lead.Answer?No.
What is the volume of a drop of oil?
The volume of one drop of anything is not a well defined quantity. However, remember that volume is an extensive property and not an intensive property. That is, it depends on the size of the sample (1 drop) and not the identity of the substance.
To change state from liquid to solid?
Drop the temperature.
What is the volume of a drop of liquid?
1/15th of one millilitre.
How many microliters are in one drop?
The size of a drop depends on the surface tension of the liquid (and gravity). A standard medicinal drop 50 microlitres.
