Two dogs pull on ropes attached to a post. Dog A exerts a force of 270 N horizontally and dog B exerts a force of 300 N. If the angle between the ropes is 60 deg find the magnitude of the resultant force and the angle it makes with Rover's rope.

To find the magnitude of the resultant force and the angle it makes with Dog A's rope, we can use vector addition. Here's the step-by-step solution:

Given:

  • Force by Dog A, FA=270 NF_A = 270 \text{ N}FA​=270 N
  • Force by Dog B, FB=300 NF_B = 300 \text{ N}FB​=300 N
  • Angle between the ropes, θ=60∘\theta = 60^\circθ=60∘

Step 1: Calculate the components of the forces

Assume Dog A's force is along the x-axis, and Dog B's force makes an angle of θ\thetaθ with Dog A's force.

The components of Dog A's force: FAx=FA=270 NF_{Ax} = F_A = 270 \text{ N}FAx​=FA​=270 N FAy=0 NF_{Ay} = 0 \text{ N}FAy​=0 N

The components of Dog B's force: FBx=FBcos⁡θ=300cos⁡60∘=300×0.5=150 NF_{Bx} = F_B \cos \theta = 300 \cos 60^\circ = 300 \times 0.5 = 150 \text{ N}FBx​=FB​cosθ=300cos60∘=300×0.5=150 N

Preparing the Children Today for Tomorrow Parents strive to have their children academically competitive. Their goal is to send their children to good schools as well as to choose extracurricular activities that improve their children's skills and abilities. Children learn what is important through their school year. The question then becomes what should parents consider in choosing the best education for their children? When should the process begin? The answer is, from the time of birth, how ever, the schools become part of the process, when children begin preschools and kinder garten. This is when parents pick a school that parallel their educational beliefs. A joint effort between parents, students, and the schools is established. Success will be based on how well the "team" works. Parents need to look for a school that will be a "second home" for their children. These are some important factors that should be considered. It is very important that students have good reading comprehension, writing and speaking skills. In today's world, students who develop skill in two or more languages will find further studies easier. English is considered the business language of today and is important for students who plan to attend university in English speaking countries. Mandarin is becoming more important as China begins to move into world economy. French and German are necessary for many students are now looking at oppor tunities in Europe. Students who develop more than one language have an advantage over competitors applying for college place ment. However one cannot develop a second language unless one develops his or her first language. Studies show that children between the ages of two and six best acquire a second language parallel to their own. Therefore, starting students in school offering dual language instruction programmes have an advantage. If a dual language programmes isn't available, or is too expensive, parents may need to look at different ways to get the needed language instruction. Language acquisition needs to be active. A good school will begin with oral language at the earliest opportunity to develop speaking confidence and to set grammatical structures. When a child learn two languages in parallel, vocabulary and grammatical structures are easier to acquire. The earlier a second language is learned, the less problem a child will have with improper word use. The more active in each language students become the more proficient and confident they will be. Taken from The Jakarta Post, 2007 33. What language should you study if you want to continue your study in Europe?

There are two crucial points on the topic of education and training of future educational psychologists. They are: the space and context of the school/educational psychologist’s performance; and the psychology undergraduate course curriculum. On the first point, it is understood and defended that there is a big difference between being an educational psychologist on the staff of a school, and acting as a school psychologist in a private office outside the institution. Even though the profession is defined by education (degree) and the purpose of the work (responding to school’s demands), it is understood that the local/position in which the professional stands makes a big difference in the role of its actions. Consequently, different elements are required in the process of the individual’s education/training, such as: knowledge about educational policies, organization and laws; training to deal with institution dynamic and continued education, etc. On the second point, it is defended that the school environment and the whole structure that delimits this space should be considered when choosing disciplines and the method of knowledge construction for undergraduate curricula design, thereby expanding the professional’s insight into other knowledge fields, such as education and politics, among others. About the curriculum related to the performance of educational psychologists outside (as consultants or autonomous professionals) and inside the school (as part of the teacher/functionary board), a discussion is proposed between the professional practice and the reflections enabled by the application of the Network of Meanings concept, which may show, among others, connections between elements. The paragraph preceding the text would likely concern with (A) psychological elements in education. (B) important points of education and training. (C) the work of educational psychologists. (D) educational policies for psychologists in developing their carrier. (E) previous discussion on educational and training of future educational psychologists

Magazine A magazine is a periodical containing a variety of articles and general illustration of an entertaining or an instructive nature. Magazines are designed to be of interest either to the general public or groups of people with specialized subject matters. The essential difference between the magazine and the newspaper is a physical one: the magazine is smaller in size and often bound in pamphlet form. Magazine production involves teamwork. This means that many people have to work together to produce the magazine you have in your hand. But one key person is the magazine editor. If someone has a manuscript he wants to publish, he will send or submit it to the editor of the magazine he likes. The magazine editor, usually the editorin -chief, will read it and make recommendation so that the manuscript can be published. Another task of a magazine editor is to consider whether the article will be part of series. Will it have photographs or illustration? will it be in full color, two or three colors, or black and white? Once the decision is made, the work of an illustrator or photographer begins. Preparing manuscripts for the magazine is hard work to do. After everything is all right, they are sent to the typesetters. When the galleys (or typeset text) come back, they must be carefully read. This is the job of a proofreader to find out whether or not there are mistakes in typesetting. Corrections are made if there are mistakes. 14. What is a proofreader's Job? a. to check the returned galleys b. to accept or refuse a manuscript c. to send a manuscript to the typesetter d. to assign illustrators and photographers
