What is the origin of Youngs modulus in metals and ceramics- Why is th.docx
What is the origin of Young s modulus in metals and ceramics? Why is the modulus of ceramics generally higher than metals?
Solution
Ceramics usually have a combination of stronger bonds called ionic (occurs between a metal and nonmetal and involves the attraction of opposite charges when electrons are transferred from the metal to the nonmetal); and covalent (occurs between two nonmetals and involves sharing of atoms). The strength of an ionic bond depends on the size of the charge on each ion and on the radius of each ion.
The greater the number of electrons being shared, is the greater the force of attraction, or the stronger the covalent bond.

Solution
Translation is the communication of the meaning of a source-language text by means of an equivalent target-language text.[1] Whereas interpreting undoubtedly antedates writing, translation began only after the appearance of written literature; there exist partial translations of the Sumerian Epic of Gilgamesh (ca. 2000 BCE) into Southwest Asian languages of the second millennium BCE.[2] Translators always risk inappropriate spill-over of source-language idiom and usage into the target-language translation. On the other hand, spill-overs have imported useful source-language calques and loanwords that have enriched the target languages. Indeed, translators have helped substantially to shape the languages into which they have translated

What is the source of elements in the universe that are more massive than helium but less massive than iron? What is the source of elements in the universe that are more massive than iron?
Solution
The source of elements in the universe that are more massive than helium but less massive than iron is \' Fusion process going on inside a massive star\'.
But all of the post-iron elements in the universe are formed in \' supernova explosions\' themselves. So much energy is released during a supernova explosion that the freed energy and copious free neutrons streaming from the collapsing core drive massive fusion reactions, long past the formation of iron.

What is the final value of x after performing the following operations (1).docx
What is the final value of x after performing the following operations? (C++)
int x = 21;
double y = 6;
double z = 14;
y = x / z;
x = 5.5 * y;
Solution
Answer: D.8
Explanation:
in line 1, x value is 21
in line 2, y value is 6
in line 3, z value is 14;
int lint 4, y = x /z will give 1.5 o y value become 1.5 at line 4
in line 5, x = 5.5 * y means
x = 5.5 * 1.5
x = 8.25
But here x is int variable, so only numeric value will assign to x. so x value is 8.

What is the difference between disk partitioning and formatting-Soluti.docx
What is the difference between disk partitioning and formatting?
Solution
Disk partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that a different file system can be used on each partition.
formatting is the process of preparing a data storage device such as a harddisk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems.
Partitioning creates logically grouped piece of memory and prepare disks for formatting. The operation allows to create logical disks. Meaning that you can have disks C, D and so on. Formatting using partitioned piece of disk to createaddress table for files to be stored.

What is the difference between interfaced system and integrated system.docx
What is the difference between interfaced system and integrated system in healthcare?
Solution
Interface acts like a bridge to shara information between the programs stll they came from two different vendors or they use two different programming constructs.An interface is having particular file format to move from among them
Integration means it works as a whole to get the result.instead of of sharing the information between them.
The usage of integration or interfaces for the health care system depends up on its usage and already existing software which is in the hands of different people in the health care system.
The interfaces are to meet the work flow of the various groups of people where as integration is usefull for overall display of the health care system such look and feel is great in this perspective. And then flexibility is more

What is the magnetic field at point Q (20cm to the left of I1, 10cm to the right of I2)? (Use positive sign, if the magnetic field points into the page, and negative sign if it points out of the page.)
?? 12 80 60 50 s40 30 20 10 0 10 20 30 40 50 60 70 80 90 x (cm)
Solution
at point P
Bnet = B1 + B2
= mue*I1/(2*pi*d1) + mue*I2/(2*pi*d2)
= 4*pi*10^-7*19.5/(2*pi*0.6) + 4*pi*10^-7*21.7/(2*pi*0.3)
= 2.10*10^-5 T (into the page)
at point Q
Bnet = B1 - B2
= mue*I1/(2*pi*d1) - mue*I2/(2*pi*d2)
= 4*pi*10^-7*19.5/(2*pi*0.2) - 4*pi*10^-7*21.7/(2*pi*0.1)
= -2.39*10^-5 T (out of the page)

What is the final value of x after performing the following operations (1).docx
What is the final value of x after performing the following operations? (C++)
int x = 21;
double y = 6;
double z = 14;
y = x / z;
x = 5.5 * y;
Solution
Answer: D.8
Explanation:
in line 1, x value is 21
in line 2, y value is 6
in line 3, z value is 14;
int lint 4, y = x /z will give 1.5 o y value become 1.5 at line 4
in line 5, x = 5.5 * y means
x = 5.5 * 1.5
x = 8.25
But here x is int variable, so only numeric value will assign to x. so x value is 8.

What is the difference between disk partitioning and formatting-Soluti.docx
What is the difference between disk partitioning and formatting?
Solution
Disk partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that a different file system can be used on each partition.
formatting is the process of preparing a data storage device such as a harddisk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems.
Partitioning creates logically grouped piece of memory and prepare disks for formatting. The operation allows to create logical disks. Meaning that you can have disks C, D and so on. Formatting using partitioned piece of disk to createaddress table for files to be stored.

What is the difference in the TLS implementation that allows some expl.docx
What is the difference in the TLS implementation that allows some exploits to work with one version but not another?
Solution
Yes in TLS implementation the benefits are vary from one version to another version.
Here some of the differences between two versions of TLS.
Comparsion of TLS 1.1 to 1.0
--------------------------------
* In TLS 1.0 we have Initialization vecor (IV). Now this is replaced with explicit IV to protect
against Cipher block chaining attacks.
* Using mac alert to handle padding errors, when decryption failed against Cipher block chaining attacks.
*For protocol parmetres, IANA registries are defined.
* Closing premature..so session cannot be resume.

What is the difference between interfaced system and integrated system.docx
What is the difference between interfaced system and integrated system in healthcare?
Solution
Interface acts like a bridge to shara information between the programs stll they came from two different vendors or they use two different programming constructs.An interface is having particular file format to move from among them
Integration means it works as a whole to get the result.instead of of sharing the information between them.
The usage of integration or interfaces for the health care system depends up on its usage and already existing software which is in the hands of different people in the health care system.
The interfaces are to meet the work flow of the various groups of people where as integration is usefull for overall display of the health care system such look and feel is great in this perspective. And then flexibility is more

what is the difference between a single beam spectrophotometer and a d.docx
what is the difference between a single beam spectrophotometer and a double beam spectrophotometer?
Solution
Only one major difference is there, remaining all are almost same.
A single beam spectrophotometer uses a reference standard to standardize the instrument before note down the measurements.
A double beam spectrophotometer splits the beam of light into two different paths, one of which passes through the sample while the other passes through a reference standard.
Hope this helped you!

What is the difference between the formation of an ionic bond and form.docx
What is the difference between the formation of an ionic bond and formation of a covalent bond?
What is the difference between the formation of an ionic bond and formation of a covalent bond?
Solution
Covalent bond: Covalent bonding is a form chemical bonding formed between two non-metals that have similar electro negativity es. For stabilization they share their electrons from outer molecule with others.
Ex:Methane(CH4)
Ionic bond: An ionic bond is formed between metal and a non metal.Non metal will have (-ve ion) stronger than metal having(+ve ion) and can get electrons easily from metal. These two opposite ions attract each other and for ionic bond
Ex:Sodium chloride(NaCl)

what is the difference an organic and inorganic molecule
Solution
Compounds which are isolated directly or indirectly from living organisms are called organic compounds. Urea, sugar, oils, fats, proteins, vitamins are some example of organic compounds.
Compounds which are isolated from from non-living sources, such as rocks and minerals are called inorganic compounds. Common salt, marble, alum, zinc sulfate are some examples of inorganic compounds.
Modern definition of organic compounds: Compounds of carbon containing usually hydrogen and one and more than other elements such as oxygen, nitrogen, sulfphur, halogens, etc are called organic compounds.
