Las lÃneas de fuerza de un campo elÃ©ctrico representan: a) las trayectorias a lo largo de las cuales no hay que realizar trabajo para mover una carga b) series de puntos equipotenciales c) la direcciÃ³n de las aceleraciones que tendrÃ¡n cargas positivas bien pequeÃ±as colocadas en distintas regiones del campo elÃ©ctrico d) la ubicaciÃ³n en el espacio de las cargas elÃ©ctricas Solution here, A more useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force Rather than draw countless vector arrows in the space surrounding a source charge, it is more useful to draw a pattern of several lines that extend between infinity and the source charge. so, The lines of force of an electric field represent c) the direction of the accelerations that will have very small positive charges placed in different regions of the electric field .

Resumen sobre las formas de calcular el campo eléctrico y los ejercicios asignados explicados paso por paso y con sus gráficos Adicional a las láminas de contenido su trabajo debe contener presentación y conclusión. Una vez que hayas resuelto los problemas de la tarea 3 debes realizar un video expositivo sobre uno de ejercicios 1. Una varilla delgada no conductora se dobla en forma de arco de circunferencia de radio “a” y sustiende un ángulo q en el centro del círculo. A lo largo de toda su longitud se distribuye uniformemente una carga total “q”. Encontrar la intensidad del campo eléctrico en el centro de circulo en función de : a , q , q. 2. Calcular la magnitud del campo eléctrico en el centro de un anillo de radio R cargado con densidad lineal l, al cual se le ha quitado un octavo de su perímetro. 3. Una carga está distribuida uniformemente en un cilindro macizo infinitamente largo de radio R. Demuestre que E a la distancia r del eje del cilindro (r < R) está dada por E = (r r / eO ) m r Siendo r la densidad de carga volumétrica ( C / m3 ) ¿Cuál será el resultado para puntos donde r > R? 4. Una esfera conductora descargada de radio R1 , tiene una cavidad central de radio R2 , en cuyo centro hay una carga puntual q. a) Encontrar la carga sobre las superficies interna y externa del conductor.

Jupiterâ€™s moon Io was discovered to have high concentrations of sulfur oxides in its atmosphere. This, in combination with research into sulfur oxides relating to pollution on Earth, has led to renewed interest in sulfur oxide compounds. One compound discovered on Io was the blue disulfur trioxide. Write the chemical formula for this compound. Express your answer as a chemical formula. Solution given disulfur trioxide it means that there are 2 Sulfur (S) atoms and there are 3 Oxygen (O) atoms so the chemical formula is S 2 O 3 .

java REQUIRES try/catch to be used with file operations. Do you understand the purpose of try/catch blocks and how/why they are used? Solution java REQUIRES try/catch to be used with file operations. Do you understand the purpose of try/catch blocks and how/why they are used? purpose of try catch operations: 1)try catch blocks are used in exception handling these are used to catch the exceptions that are found during compilations 2)java requires try catch blocks in file operations because the these file operations are situated in java.io.*; 3)so here these file operations throws filenot found exceptions try { FileReader fr=new FileReader(\"......txt\"); } catch { system.out.println(\"error in data\"); } .

Java Programming Solution Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers \"write once, run anywhere\" meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. Java is one of the most popular programming languages in use, particularly for client-server web applications Example: .

Java Programming. How do you go about debugging your code? What is the trickiest bug you have, and how did you end up fixing it? Solution what is debugging? Debugging allows you to run a program interactively while watching the source code and the variables during the execution. Debugging in Eclipse:- 1. Setting Breakpoints 2. Starting the Debugger 3. Controlling the program execution 4. Breakpoints view and deactivating breakpoints 5. Evaluating variables in the debugger 6. Changing variable assignments in the debugger 7. Controlling the display of the variables with Detail Formatter We need to look after these to debugg. It is in Eclipse .

Jack is sitting on a plank of uniform wood of length L that his dad and mom, Jason, Jun, are holding. Jack is sitting 1/4 of the length of the plank of wood away from his father. If the mass of the plank of wood is M, Jack\'s mass is m, and the plank of wood and Jack are in static equilibrium. a. What is the force F 1 provide Jason? b. What is the force F 2 provided by Jun? Solution Suppose Jason is on left side and Jun is on right side to tha Jack. Weights of Jack and plank areare mg and Mg Now, taking moment about Jun\'s end F1 *L = Mg*(L/2) + mg * (3/4)*L So, F1= (2Mg + 3mg)/4 And F2 = mg + Mg - F1 F2=( 2Mg+ mg)/4 .

Janicex Co. is growing quickly. Dividends are expected to grow at a rate of 20 percent for the next three years, with the growth rate falling off to a constant 5 percent thereafter. If the required return is 14 percent and the company just paid a dividend of $2.50, what is the current share price? Solution GIVEN D 0 = $2.5 g = 20% Ke= 14 % D 1 = D0 * (1+g) = 2.50 ( 1 + 0.20) = 3 D2 = D1 * (1+g) = 3 * (1+0.20) = 3.6 D3 = D2*(1+g) = 3.6* (1+0.20) = 4.32 Growth rate after 3 years, falling off to a constant rate = 5 % D4 = D3 * (1+g) = 4.32 * (1 + 0.05) = 4.536 current share price = D4 / (Ke - g) = $ 4.536 / (0.14 - 0.05) = $ 50.4 .

Which of the following potential errors in performance appraisals has Laura committed? Forced-choice Leniency Central tendency Alternation bias Recency Solution Leniency She doesnâ€™t evaluate any bodyâ€™s work critically then she has to rate someone good and some one bad along with average in order to maintain the normalcy in performance. In this case she rate everyone average thus maintain the average of the performance. .

java! what is the advantage of byte based files over character based file? Solution Advantages of byte based files over character based files: a.) thisbyte based class is not used directly,but when it is used,then binary data is expected in the end and it consists of many subclasses. b.) bytes can be easily converted to characters using encoding because of wrapper and the process of encoding is done with the help of constructors. c.) byte based files can be more efficient when it comes to reading binary files like images and sounds. d.) byte based files interact with the system to serve special purposes while the character based files do not as the character based files cannot manipulate binary data,character based files can only manipulate sequence of characters for storing. .

Kumar Innovation Co had the following line item on its 12/31/2014 Balance Sheet 12/31/2014 Accounts Payable $10,000 Kumar\'s Statement of Cash Flows had the following line item: 2014 Change in accounts payable $4,000 Assume that the company madeno acquisitions or divestitiures and that all operations are in the home country. How much Accounts Payable did Kumar have on 12/31/2013? Solution Answer: Change in Accounts payble of $4,000 is a positive figure, so added in the cash flow statement. And as a rule increse in Accounts payble are added in cashflow statement. Account payble as on 12/31/2014 = Account payble as on 12/31/2013 + Increse in Accounts payble => $10,000 = Account payble as on 12/31/2013 + $4000 => Accounts payble as on 12/31/2013 = $10,000 - $4,000 = $ 6,000 (Ans) .
