Diffraction effects are observed when electromagnetic radiation impinges on periodic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0. 15–0. 4 nm which correspond in the electromagnetic spectrum with the …
Radiotherapy intervention has a important and critical axial rotation in the intervention of cancerous diseases. Different types of techniques were used for this intent. In past, conventional radiation therapy technique was used. But it did non efficaciously used for intervention of tumours located in sensitive …
The time and temperature change of the reaction are graphed to identify the hanged in enthalpy and entropy that took place as the melted substance solidifies. Using the data we can then predict the change in free energy, GAG . Keyword’s: Entropy, Enthalpy, Free energy, …
Scientist around the world studies the stars and planets to learn more about the past or to learn how that and our planets are alike. But then there are other scientist who got even deeper and learn what created the planets and stars these scientist …

As a result of the current global warming issues and the ever growing scarcity of our current energy resources we may be forced to resort to nuclear energy. The Department of Energy has already given its support to energy companies who have decided to construct …
Statement of the research: We consider steady laminar and fully developed fluid motion in the annulus of two circular pipes with longitudinal fins attached to the outer surface of the inner pipe. The fins are straight, non porous and uniformly distributed around the region with …
A pure substance: • contains atoms of only one kind. • It has fixed physical and chemical properties like boiling point, melting point, valency, density • contains only one chemical identity, e. g. one element or one compound. • cannot be separated into 2 or more substances …
Stock Repurchase Repurchase of stock can be viewed in each of the following way: investment, financing, shareholder distribution and control issue. Repurchase of stock can be a way to use firm’s excess debt capacity. By doing so, firm can lower the cost of equity financing. …
Setting up the paradigm. How do we know there is a God? If anything exists there is a God because you cannot create something from nothing. There had to be an initial force to set the universe into motion. Einstein refers to this force as …
Atoms are the smallest entities which resemble the properties of an element and cannot be broken down into smaller parts. Molecules are formed when two or more atoms are combined. This formation can happen in a variety of ways. When two oxygen atoms join O2 …

Magnitude
In physics, magnitude is described in simple words as 'distance or quantity'. It shows the direction or size that is absolute or relative in which an object moves in the sense of motion. It is used to describe the size or extent of something. Generally, in physics, magnitude relates to distance or quantity.
Equilibrium
equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
