Black holes are formed from the gravitational collapse of dying stars. They have immense gravity due to their extremely compact size, with some only a few hundred meters in diameter despite being very massive. Any object falling into a black hole would be ripped apart by the intense tidal forces it experiences as the side facing the black hole would be pulled much more strongly than the far side, eventually tearing the object into tiny pieces.

Education

Black Holes are cores of dying stars that have gravitationally collapsed even more then a neutron
star (a neutron star is somewhat stable because of the pressure created by the compressed
neutrons, which will counter the force of gravity). A black hole is basically infinitely small, but
its radius is usually defined as the radius from which light can escape. Even for very massive
stars this radius is small (we are talking a few hundred meters here compare to the 700,000km of
your Sun). If you would fall towards such an object, your biggest problem would be that you
need to deal with tidal forces. Explain why these tidal forces will cause all objects to be ripped
into tiny pieces.
Solution
The tidal forces will cause all objects to be ripped into tiny pieces. How ??
Let's take an example - suppose we are falling toward the black hole with our legs towards the
center. At the start, we will feel equal gravitational force all over the body. As we approach the
center of black hole, the gravitational force on the legs will intensify and the gravitational force
on the head will not be that high, this will generate a tidal gravitational force. These tidal forces
get more and more intense as we get closer to the center, and eventually they will rip us apart.
This is same as the moon tugs harder at the side of the Earth closest to it, causing the tide to rise
up towards it, the black hole pulls harder at our feet than it does on our head.
Same will happen with any object falling into the black hole.

Beyond aesthetics, what functional differences are there for running GNS3 as root versus running GNS3 as a non-root user? FUNCTIONAL DIFFERENCES FOR GNS3 NOT DB2. Solution During a root installation, subdirectories and files for the DB2 database product are created in a directory of the root users choosing unlike root users, non root users cannot choose where DB2 database products are installed.Nonroot installations are always placed in the $HOME/sqllib directory where $HOME represents the non root users home directory.The layout of the subdirectories within the sqllib directory of a non root is similar to that of a root installation For root installations, multiple instances can be created.Instance ownership is associated with the user id under which the instance was created Non root installations can have only one DB2 instance.The non root installation directory contains all of the DB2 database product files and instance files with no soft links. The following table summerizes the differences between root installations and non root installations user can select instalation directory .

Beside the typical DBMS, what are some of the different data sources that an Internet application may need to access for data? Can a database be an integrator of these different data sources? Solution There are two types of data sources: Database Data Sources A database is a grouping of tables in a database management system. You must identify databases to the applications that access them. You can distribute databases across a network and involve various servers and database management systems. A database data source identifies the database information that the software needs to connect to a database. Logic Machine Data Sources A logic machine is the machine on which batch applications and master business functions run. You must identify logic machines using a data source definition. The data source definition must include the network information about the machine, such as a server name - HP9000, for example. When mapping logic objects for distributed processing, the software uses the machine data source (distributed processing data source) as the target location for processing logic objects. .

Based on the information in “Atom: Clash of the Titans”, please answer the following questions: 1. Why was it so important that the scientists investigating the atom be young and unattached to existing scientific thinking? 2. What connection did Bohr discover between atoms and light? 3. Why did Einstein hate Bohr’s ideas - quantum mechanics, electrons jumping and releasing light - about the atom? Solution 1) The scientists investigating the atom should be young as was then the young scientist Albert Einstein. His harsh arrogance led him barely any employment, thereby because of his undemanding job he had a lot of time to have deep thoughts. And that was the era wherin he worked on to prove the existence of atom. Though it was Boltzman who started work on this topic but due to his health conditions and alegations on him being irrelegious materialist lead to him comitting suicide. And the scientists should be unattached to existing scientific thinking as was scientist Neil Bohr who was fearless in his thinking and was ready to abandon common sense and human intution to find an explanation. 2)Bohr\'s connection between atoms and light was as follows-quantum jumps Light is emitted when an electron jumps from a higher orbit to a lower orbit and is absorbed when jumps from lower to higher orbit. In order to overcome the limitations of Bohr model and to develop a general model for atoms.The 2 developments contibuted a lot - 3)As the bohr idea of new atom and quantum jumps were not so traditional neither they matched classical science theories thus the old school people strongly opposed it. And Albert Einstein was one of them as he wanted to save the world of order and wanted to preserve the common sense. .

Both these questions go together Solution When we bring a magnet near a metal, the metal enters a magnetic field, all of the electrons inside the metal \"line up,\" causing a temporary magnetic alignment that is attracted to the magnet . That alignment dissipates once the magnetic field is removed and therefore, the only way for a metal to be repelled by a magnet is if it\'s first magnetized to the opposite pole. so if the metal is magnetised and the a magnet with the same pole is brought near it will repel Note:- its easy to magnetise a iron piece just rub the magnet over the metal in one direction many, many times. By rubbing a magnet over your metal continuously, you are aligning the electrons in the metal in a certain way, toward a certain polarity. The more that you do this, the longer the effect will last, taking more time for the electrons to return to their random or unpolarized state. so the answer to the question is 1) c 2) d .

Boston Scientific faced the challenge of balancing openness and sharing with security and the need for restricting access to information. How did the use of technology allow the company to achieve both objectives at the same time? What kind of cultural changes were required for this to be possible? Are these more important than the technology- related issues? Develop a few examples to justify your answer. Solution The use of technology will definately allow the company to achieve both objectives at the same time. It explained in below given points . 1. With in the company we can apply the access rights on users level. We can identify the various group of users, and according to the need of users group, we can apply various access rights to each users groups. 2. Let take an example of social networking websites, lets suppose we have two users group in the company named A and B, where A have customer interfacing, so for user group A , we can enable the use of social networking websites, to communicate and make good relationship with customers. 3. Same can be done with company related emails also. We can sent the company related emails with digital signature. Here in this case the authentic user who having access rights can access the emails signed with digital signature. Technology related issues are more important t han the cultural changes, In terms of cultural changes, we can change the setting arrangements within the organization, so that users or the employess with same access rights sit together, and employess with less access rights sit together in other places. Because if both type of employess sit together then it can happen than authentic information gets leaked. .

Based on the information in “Atom: Clash of the Titans”, please answer the following questions: 16. Why did Heisenberg want to destroy Schrödinger’s wave equation?What happened when he tried to call out Schrödinger in public? 17. Almost the entire scientific community had turned on Bohr and Heisenberg, saying that their “matrix mechanics” model of the atom was wrong. Why did they refuse to give up their ideas and admit they were wrong? please use correct sentences Solution 16. Heisenberg stated that the position and the velocity of particle / wave cannot be found at some point in space simultaneously. On the contrary Schrödinger wave equation gives the position of an atom and with defined quantum aspects of a system. However in the end these 2 theories went hand in hand. 17. Using this matrix mechanics which has superseded the Bohr\'s model, Heisenberg predicted that the electrons might not be revolving in orbits. The mathematics used to describe the model were unknown and uncertain to the scientific community. They refused to agree with the discrete energy states concept Nevertheless this was also complementing the Schrödinger’s wave equation which was widely accepted during that period of time. .

6. What are the differences between objects and abstract data types Solution Differences between Objects and Abstract data types: ______________________________________________ Objects: Object is an instance of a class and it has states and behaviours of class. Abstract data type: It is a data type of abstract and it hides the representation of class, and it is typically implemented as a class and each instance of Abstract data type is usually an object of that class. Objects and Abstract data types are not the same. But these are not different with each other. Objects are a kind of Abstract data types. An Abstract data type is an interface.But objects are instance of a class, with its own copy of any non-static variables. Abstract data type is a collection of methods but in case of objects it is not an interface.It is an representation of a class with new operator. A class can have one or more Abstract data types in the same way class can have one or more objects also. To understand you with clear for Example, Collection interface is Abstract data type, ArrayList is a class and you can make ArrayList object with new operator. .
