Defects in Rutherford’s model

Although Rutherford’s experiment proved that the, plum-pudding, model of an atom was not correct, yet it had following defect:

1.    According to classical theory of radiation, electrons being the charged particles should release or emit energy continuously, they should from a continuous the nucleus.

2.    If the electrons emit energy continuously, they should form a continuous spectrum but in fact, line spectrum was observed.

Although the scientists had objections on the atomic model pres

ented by Rutherford, yet it cultivated thought provoking ideas among them. They initiated the quest to answer the following questions:

1.    How can an atom collapse one why are atoms stable?

2.    Why does an atom give line spectrum?

Scientists considered there must be another model of atom.

It indicated that Rutherford’s model was not perfect.

International system of units

Measuring is not simply counting. For example, if we need milk or sugar, we must also understand how much quantity of milk or sugar we are talking about. Thus, there is a need of some standard quantities   for measuring\comparing unknown quantities. Once a standard is set for a quantity then it can be expressed in terms of that standard quantity. This standard quantity is called a unit.

       With the developments in the field of science and technology, the need for a commonly acceptable system of unit was seriously felt all over the world particularly to exchange scientific and technical information. The eleventh general conference on weight and measures held in Paris in 1960 adopted a word-wide system of measurements called international system of unit. The international system of unit is commonly referred as SI.

what is cell

 Cytoplasmic organelles are "little organs" that are suspended in the cytoplasm of the cell. Every single variety of organelle has a definite framework and a certain position in the perform of the cell. Examples of cytoplasmic organelles are mitochondrion, ribosomes, endoplasmic

 atomic mass atomic mass system

as we understand that the mass of an atom is as well tiny to be determined figured out virtually. nonetheless, particular tools enable us to identify figure out the proportion of the atomic masses of numerous aspects components to that of carbon_12 atoms. this ratio s referred to as the relative atomic mass of the element aspect. the relative family member atomic mass of an aspect is the ordinary mass of an atoms of that element aspect as compared with 1/12th (one_twelfth) the mass of an atom carbon_12 isotope (a component having various mass number however exact same atomic number). based upon carbon_12 standard, the mass of an atom of carbon is 12 as well as| 1/12th of it comes to be one. when we contrast atomic masses of various other aspects with carbon_12 atoms, they are revealed as relative atomic masses of those components. the device for relative atomic masses is called atomic mass device, with sign, amu,. one atomic mass unit is 1/12th the mass of one atom of carbon _ 12th. when this atomic mass device is shared in grams, it is:
1 amu= 1.66x10-24g.

in science when carrying our undertaking the experiment, it have to be a |managed experiment. the scientist need to contrast an experimental group with a centro handle group. the two groups are taken care of specifically alike except for the one particular variable currently being examined. for illustration in an experiment to |check the necessity of carbon dioxide for photosynthesis, one particular can contrast the control manage group a plant with freely offered carbon dioxide with an experimental group  a plant with no carbon dioxide obtainable. the necessity of carbon dioxide will be proved when photosynthesis takes place in the centro management group and does not take in the experimental group.

Mustard plants

Mustard plant {taxonomic name}: brassica campestral is planted in winter as well and also it generates
Seeds at the end of wintertime months. The plant body is utilized made use of as veggie as well and also its seeds are utilized made use of for extracting drawing our removing oil. The body organs of the body could be separated right into two teams on the basis of their features. Origin, stem, branches and and also fallen  are the vegetates body organs, which do not participate in the sex-related duplication of the plant. Floral are the reproductive components of the plant due to the fact that they participate in sex-related duplication and also generate fruits and also seeds.
