The total acceleration of an object rotating with increasing angular speed is given by the vector sum of the radial acceleration component and the tangential acceleration component (choice b). As an object rotates, it experiences both radial acceleration towards the center of motion and tangential acceleration as the tangential velocity increases due to rising angular speed over time. The object's total acceleration is calculated as the vector sum of these two perpendicular components.

Answer is b and why?
10.5.3. As an object rotates, its angular speed increases with time. Complete the following
statement: The total acceleration of the object is given by a) the vector sum of the angular
velocity and the tangential acceleration component divided by the elapsed time. b) the vector
sum ofthe radial acceleration component and the tangential acceleration component. c) the
angular acceleration. d) the radial acceleration component. e) the tangential acceleration
component.
Solution
When an object rotates, it experiences radial acceleration(directed towards the center of motion).
Also, since the angular speed is increasing with time, so will the tangential velocity. Therefore,
the object will also be subjected to tangential acceleration which is directed tangentially.
therefore, the objecte is subjected to both radial and tangential acceleration.
Since they are directed perpendicular to each other, the total acceleration=vector sum of radial
and tangential acceleration

An unknown mixture of ions was treated with hydrochloric acid resulting in a white precipitate and a colorless solution. The precipitate did not change after addition of hot water but did disappear after addition of ammonium hydroxide. After acidification with nitric acid, the white precipitate reappeared. The colorless solution was treated with thioacetamide and hydrochloric acid resulting in the formation of a dark precipitate. The precipitate was treated with nitric acid resulting in a black precipitate and blue solution. The blue solution was treated with sulfuric acid and ammonium hydroxide without changing. After addition of sodium thiosulfate, a reddish-brown precipitate appeared. Determine which ions were present in the unknown mixture. Select all which apply.

Analyze the role cryptographic algorithms play and explain how these algorithms could be utilized in a way that would strengthen an organizationâ€™s existing plan. Solution Cryptographyâ€™s Role in the Enterprise Encrypting every piece of data in your organization keeps data protected from unauthorized access. Every organization has confidential data. It has to be protected such a way that only an authorized person could access it. Cryptographic algorithms strengthen an organizationâ€™s existing plan by providing below benefits. Confidentiality Encryption technique can guard the information and communication from unauthorized revelation and access of information. Authentication The cryptographic techniques such as MAC and digital signatures can protect information against spoofing and forgeries. Data Integrity The cryptographic hash functions are playing vital role in assuring the users about the data integrity. Non-repudiation The digital signature provides the non-repudiation service to guard against the dispute that may arise due to denial of passing message by the sender. .

Analyze and determine which sector, public or private, has greater insight on the potential of cyberattacks. Solution Private Sectors has a greater insight on the potential of cyberattacks The threat of hacking varies from one sector to another sector and it is difficult to measure it because intrusions often go undetected. Risk awareness is growing and reducing the risk is difficult because threats evolves constantly. Business possessing great quantities of personal data have a higher insight of potential risk Regulated and large corporations tends to be more douced on risks assocated with cyberattacks. However the extext of cyberattacks on private sector will always depends on the maturity of an organization, the cybersecurity implemented by organization and the holistic sexurity safegaurds .

Describe the term amphipathic Give an example of a non-amphipathic lipid. Solution a) An amphipathic molecule is the one which comprises of two parts : All the lipids molecules found are amphipathic in a cell membrane. b) Out of all the four compounds given in the question the one responsible for controling the development of sex organs and secondary sexual characteristic is the compound C. The name associated with this type of compound is ANDROGENS. Yes androgens will react with NaBH 4 and reduces 1-carbonyl group of 3-deoxy androgens to form aromatase inhibitors having a 19-hydroxy group. c) The compound A can be identified as local hormone. The name of the compound is ALPROSTADIL. These molecules are called local molecule these are produced by cells and to either neighboring cells(i.e. local to their neghbourhood ) or the same tupe of cells that are responsible for their production. These hormones are very quickly inactivated.These are large group of signalling molecules and are released during phisical activity like exercise and running. These hormones donot circulate within the blood thus are local to their production area. d) Compound B is a major component of biological membrane. Yes these compounds are hydrolysable due to the fact that they contain ester group. These compounds are hydrolusable because tehy contain funtional group ester. .

Analyze the types of informal and formal communication in organizations. Solution Formal Communication: A communication that is made in the proper channel and which is properly authorized is defined as a formal communication. In formal commication, the message that is conveyed will be recorded for future reference. The various types of formal communication in an organization as as follows: 1.Circulars 2. Notices put up on notice boards 3. Important annoucements 4. Formal E-Mail 5. Notifications from Immediate senior Informal Communication: Any communication that does not have an origin or an end is called as an informal communication. In other words a communication in which the sender and receiver are not definite is called as an informal communication. The various types of informal communication in an organization are as follows: 1. Gossips 2. Rumours 3. Organization secrets that gets communicated informally. 4. Information that is passed between departments without following the hierarchy of authorization .

Encapsulation process. Explain this process giving specific detail at each layer of the OSI Model. Be sure to explain the different PDUs at each stage and include the most significant fields for each pdu. (20 marks) Solution Its dvided into seven layers. Encapsulation happens seperately at different levels. Starting frm Application layer, application running on source device creates some kind of data.Then next comes Presentation layer where encryption gets added to the data. Then the session layer where session id is applied.Upto this point information is still one block of data. Next layer is transport layer where bock of data gets break down into segments and gets a port number. This segment is then passed to Network layer where source and destination IP address are appended and now the segment becomes packet.This packet is then passed to next level called Data link layer where destination MAC address and CRC is added.Now the resulting thing is Frame. The Frame then is sent to the physical device where it is translated into some kind of a signal, whether itâ€™s electrical, radio wave, light or other signal. This Frame then becomes some kind of a signal that represents a series of zeros and ones. This is why at the Physical layer we often call it Bits .

Elijah Murphy studied voice, opera, and Jewish liturgical music at the Southern Baptist Theological Seminary. After he graduated, he applied for a job as a cantor (i.e., professional singer who leads prayer services) at the Nashville Downtown Synagogue. The synagogue responded that he was not qualified for the position and refused to consider him for the job because he is not Jewish. A. Elijah has a prima facie case of disparate treatment discrimination against the synagogue and the synagogue has no defense. B. Elijah has a prima facie case of discrimination against the synagogue and the synagogue can successfully assert the ministerial exception to Title VII. C. Elijah does not have a prima facie case of discrimination, so it doesn\'t matter whether the synagogue can assert a defense. D. Elijah has a prima facie case of discrimination against the synagogue and the synagogue can successfully assert the business necessity defense. Solution B. Elijah has a prima facie case of discrimination against the synagogue and the synagogue can successfully assert the ministerial exception to Title VII. As Elijah was refused to consider for the job because he is not Jewish, therefore Elijah has a prima facie case of discrimination against the synagogue as he had studied voice, opera, and Jewish liturgical music at the Southern Baptist Theological Seminary and have skill level. Synagogue can successfully assert the ministerial exception to Title VII, as he responded that he was not qualified for the position and refused to consider him for the job because he is not Jewish. .
