16) What are the two types of current? What is different about the flow of electrons? (think of our class demonstration) 17) What phenomena is responsible for how generators and motors work? 18) Light, electromagnetic wave, photons, radiation, all refer to the same phenomena and are synonyms 19) A changing magnetic field creates an electric field and a changing electric field creates a magnetic field 20) What phenomena is responsible for how motors and generators work and who discovered it? 21) What is an element\'s Atomic number tell you? 22) Matter is mostly empty space 23) Can electricity flow in an open circuit? 24) The unit of Power is Watts (say what!). The unit of Energy is Joules usually denoted by a J 25) What are the different ways that light interacts with matter? 26) What is the speed of light in miles per second? 27)Light is both a particle and a wave. Light is also massless (I forgot to say in class)! Solution 16) Direct current DC : electrons flow in single direction Alternating current AC : electrons flow in 2 directions 17) Electromagnetic induction 18) Electromagnetic radiation (spectrum) 19) Electromagnetic field 20) Electromagnetic induction, Michael Faraday discovered this 21) Atomic number gives number of protons present in the nucleus of the element and this decides the position in periodic table. 22) Yes, 99.999 % of an atom consists of empty space the rest of 0.01% consists of nucleus, protons, electrons etc 23) Yes it does flow, but it very much feeble and limited.

lectromagnetism Concept : Theory to Applications | Superb Explanation ! | 2024 As we know at the microscopic level there are some charges and these charges have the force of attraction between them. Here electromagnetism is a force that governs the behavior of electrically charged particles. It is a branch of science that deals with the interaction between an electric field and a magnetic field and the way they interact with matter and each other. Table of Content : (Electromagnetism Concept) What is electromagnetism? How does electromagnetism work? What are the applications of electromagnetism? What are the disadvantages of electromagnetism? FAQ : (Electromagnetism Concept) what is a real-life application of electromagnetism? what is the definition of electromagnetism? who originated the branch of electricity generally described as electromagnetism? who came up with the idea of classical electromagnetism? What is electromagnetism? 1 . (Electromagnetism Concept) Electromagnetism is the study of electric charges and the magnetic field they produce. As we know electric charges are of two types positive and negative. So these electric charges create an electric field around them similarly moving charges generate magnetic fields and the interaction between this electric and magnetic field gives rise to electromagnetism. How does electromagnetism work? 2 . (Electromagnetism Concept) The behavior of electromagnetism is described by Maxwell. He has derived some equations, these equations mathematically describe how electric and magnetic filled interact and propagate through space. According to Maxwell’s equation changing the electric field-induced magnetic field and changing the magnetic field-induced electric field both create a self-sustaining cycle of electromagnetic waves. What are the applications of electromagnetism? 3 . (Electromagnetism Concept) Electromagnetism finds various applications across various fields, it has great potential in revolutionizing technology and shaping modern civilization. Some of the real-life applications of electromagnetism are given below:- Electromagnetic induction:-By inducing electric current in a conductor through a changing magnetic field electromagnetic induction enables the generation of electricity on a large scale. With the help of this phenomenon, electricity can be produced in a huge amount. Electromagnetic waves:– Electromagnetic waves are of various types and the propagation of electromagnetic waves such as radio waves, microwave and light waves form the basis of modern communication systems from radio broadcasting to wireless internet electromagnetic waves facilitate long-distance communication and information exchange. Electromagnetic devices:- Electromagnetic devices including electric motors, Magnetic resonance imaging, and electromagnet work on the principle of electromagnetism. Electric motors convert electrical and More !

Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. What causes the electric and the mgnetic field in the air? Solution Let see how we can truly understand what EMwaves are. Electromagnetic waves are a form through which energy is transmitted. These waves are made up of electric and magnetic fields. They can travel through a medium (such as air) as well as through vacuum. Thus, we can imagine EM waves as packets of energy. Light is an EM wave. Light is made up of oscillating electric and magnetic fields. However, light itself also acts as a particle (wave-particle duality). Thus there is no other particle or medium required to cause the fields. Thus, no component of air causes the electric and magnetic fields in EM waves. Rather EM themselves are particles (so to say) causing the oscillating electric and magnetic fields, irrespective of medium. .

Describe how meiotic and mitotic nondisjunctions occur and their pos.pdf

ezycolours78

Describe how meiotic and mitotic nondisjunctions occur and their possible phenotypic consequences Solution 1. Meiotic non disjunction basiclly happens in meiosis II. Ovulated eggs become arrested in metaphase II until fertilization triggers the second meiotic division. Similar to the segregation events of mitosis, the pairs of sister chromatids resulting from the separation of bivalents in meiosis I are further separated in anaphase of meiosis II. As a consequence, different phenotypes will be observeed: In oocytes, one sister chromatid is segregated into the second polar body, while the other stays inside the egg. During spermatogenesis, each meiotic division is symmetric such that each primary spermatocyte gives rise to 2 secondary spermatocytes after meiosis I, and eventually 4 spermatids after meiosis II. 2. Mitotic non-disjunction occurs in the mitosis. In mitosis, each chromosome consists of two sister chromatids held together at the centromere. In the anaphase of mitosis, sister chromatids separate and migrate to opposite cell poles before the cell divides. Nondisjunction during mitosis leads to one daughter receiving both sister chromatids of the affected chromosome while the other gets none. As a consequence, Mitotic nondisjunction results in somatic mosaicism, since only daughter cells originating from the cell where the nondisjunction event has occurred will have an abnormal number of chromosomes..

An epic bribe scandal at Petrobras, a major oil company controlled b.pdf

ezycolours78

An epic bribe scandal at Petrobras, a major oil company controlled by the Brazilian government, that broke out in 2015 shocked the economic and political system of Brazil. Put simply, the company insiders, outside suppliers and contractors, and politicians colluded and stole billions of dollars from the company via kickbacks, bid riggings, overcharging for construction projects, and the like. The Petrobras scandal led to a sharp drop of the company share price, laying off thousands of workers, and tilting the national economy toward recession. The scandal also seriously tarnished the image of Brazil as a promising emerging market. Discuss in detail what happened at Petrobras and then investigate how the company’s governance and the country’s political culture may have contributed to the scandal. At least 6 sentences: 1 point Grammar and punctuation: 1 point Paragraph with transition sentences: 2 points Appropriate and relevant content with explanation: 4 points Solution Operation carwash was a widespread money-laundering scheme in a state owned enterprise in Brazil called Petrobras that was exposed in 2014. This scandal involved Petrobras top management and high-ranking officials from the Brazilian federal government. A brief summary of the scandal: Paulo Roberto Costa who was the chief of Petrobras refinery from 2004 to 2014 unfairly used his relationships with six of large construction firms in Brazil. These firms were awarded contracts from Costa’s division and they overvalued these contracts by 3%. Petrobras employees turned a blind eye when evaluating bids to these contracts. The overvaluation thus created excess capital for the company. The excel capital was siphoned off in three ways- the officials from construction company pocketed some amount of excess funds, and rewarded their partners inside Petrobras. Some of the funds were also diverted to ruling political parties in terms of gifts, donations etc. The total value of bribes involved in this scandal is approximated somewhere between 3Bn to 5.3Bn USD. Contribution of company’s governance model into scandal: Contribution of country’s political culture into scandal.

2.Distinguish between assigned and emergent leaders. Give an example.pdf

2.Distinguish between assigned and emergent leaders. Give an example of an instance in which you \"emerged\" as a leader. Explain how your communication might have facilitated your emergence as leader. Solution In most of the organisations today, there are broadly two types of leadership. One is the “Assigned leadership” and another one is “Emergent leadership”. The difference between the assigned and emergent leadership is that in the assigned leadership, a person is explicitly appointed to hold a particular position in the organisational structure. This is a more common and traditional form of leadership where at the time of recruiting itself, the candidates are conveyed by the human resource managers about the position they are being hired for such as team leader, area sales manager, vice president, etc. Where as in the emergent leadership, a person is not appointed, recruited or elected to a leadership role. Instead, the person himself or herself emerges as a leader of the team or group he or she is a part of, as a result of his or her interaction with the group over a period of time. The most successful companies of the world are focussed on the emergent form of leadership to add value to their organisations. The emergent leaders are usually the ones who have spent a lot of time with the organisation, have undergone multiple business cycles and knows the in and out functioning of the organisation. They are effective communicators and understand company process and policies better than most of the people in the company. Because of their superior domain knowledge and productive way of doing things, they emerge as leaders of their team. In one of the early assignments of my career, I was working as a direct sales representative in a leading public sector bank. I was tagged to a branch out of more than 1200 branches that the bank had in the country. Direct sales representatives (DSTs) are responsible to get more customers and more business for the bank by moving in the field all day and interacting with different types of prospective customers. These customers included both the retail and the corporate customers. During my two and a half years tenure with the bank, I was a consistent top performer in terms of the volume and value of the business generated by each direct sales representative per month. I had an excellent product knowledge on every banking product that the bank had to offer such as savings account, current account, fixed deposits, recurring deposits, third party insurance, home loans, car loans, business loans, debit and credit cards and all other assets and liabilities products. In a very short period of time, I emerged as the leader of the direct sales representative team by becoming a team leader of the DSTs of my branch and the regional head of all the direct sales representatives of our region (covering more than 15 branches) at the time of my exit from that particular bank. I believe, in my emergence as a leader, my effe.

ezycolours78

To complete the task, you need to fill in the missing code. I’ve included code to create an Iterator. An Iterator is an object that iterates over another object – in this case, a circular linked list. You can use the .next() method to advance the Iterator to the next item (the first time you call it, the iterator will travel to node at index 0). Using iterator’s .remove() removes the node the iterator is currently at. Say that we had a CircularLinkedList that looked like this: A ==> B ==> C ==> D ==> E ==> Calling .next() three times will advance the iterator to index 2. Calling .remove() once will remove the node at index 2. A ==> B ==> D ==> E ==> Calling .remove() once more will remove the node now at index 2. A ==> B ==> E ==> The Iterator methods handle wrapping around the CircularLinkedList. Be sure to create the iterator using l.iterator() and after you’ve added all the nodes to the list, where l is your CircularLinkedList Solution import java.util.Iterator; class CircularLinkedList implements Iterable { // Your variables // You can include a reference to a tail if you want Node head; int size; // BE SURE TO KEEP TRACK OF THE SIZE // implement this constructor public CircularLinkedList() { head=null; } // writing helper functions for add and remove, like the book did can help // but remember, the last element\'s next node will be the head! // attach a node to the end of the list // Be sure to handle the adding to an empty list // always returns true public boolean add(E e) { Node newNode=new Node(e); if(size==0){ head=newNode; } else{ Node last=getNode(size-1); last.next=newNode; } newNode.next=head; //last element node is set to head size++; return true; } // need to handle // out of bounds // empty list // adding to front // adding to middle // adding to \"end\" // REMEMBER TO INCREMENT THE SIZE public boolean add(int index, E e){ if(index>size) return false; Node tmp=new Node(e); if(index==0){ tmp.next=head; Node last=getNode(size-1); head=tmp; last.next=head; } else { Node curr=getNode(index-1); tmp.next=curr.next; curr.next=tmp; } size++; return true; } // I highly recommend using this helper method // Return Node found at the specified index // be sure to handle out of bounds cases private Node getNode(int index ) { Node prev=head; for(int i=0;isize) { e=null; } else if(index==0){ e = head.getElement(); Node last=getNode(size-1); head=head.next; last.next=head; size--; } else{ Node prev=getNode(index-1); Node curr=getNode(index); e=curr.getElement(); prev.next=curr.next; size--; } return e; } // Turns your list into a string // Useful for debugging public String toString(){ Node current = head; StringBuilder result = new StringBuilder(); if(size == 0){ return \"\"; } if(size == 1) { return head.getElement().toString(); } else{ do{ result.append(current.getElement()); result.append(\" ==> \"); current = current.next; } while(current != head); } return result.toString(); } public Iterator iterator() { return new ListIterator(); } /.
