Consitution of 1962 Background On 7 Oct 1958 the military assumed power in Pakistan under the leadership of general Ayub Khan who was the Commander in Chief at that time. The military abrogated the Constitution and the federal and provincial cabinets were abolished. The national and provincial assemblies were also abolished and martial law was imposed in Pakistan.Ayub Khan became the chief martial law administrator and in this way the 1st military govt came into existence in Pakistan. During

variable represents the length of the string and the dependent variable represents the period of one oscillation. The control variable is the mass of the pendulum. In this lab our goal was to see if we can prove if the acceleration due to gravity is 9.8m/s2. The R2 in this lab is closed to 9.8 m/s2 . The formula that we used in this lab is T=2πLg and then we solved for g=L(T2π)2. HYPOTHESIS: The gravity will be 9.81 m/s2 at sea level due to the acceleration. PROCEDURE: Materials: stopwatch‚ meter

Answer the following: Mimi Meowz is a large designer-clothing company that sells mainly to large retail department stores‚ as well as to smaller boutique shops. The company requires its salespeople to use notebook computers to enter orders from customers. This information is then transmitted to its warehouses‚ where orders are shipped on a first-come‚ first-served basis. Unfortunately‚ the stores are aware of this shipping policy and are extremely competitive about which one of them will offer a

Can Detour Protein Candy Bars make you look attractive? In our daily lives we are exposed to advertisements that can impact us negatively or positively. When we look at an advertisement we tend to look at what is being advertised but if we looked more closely‚ there is always a story that is trying to be told to us. Several advertisements can bring negative stories that can be sometimes sexist. Sexist ads portray women as objects in order to convince consumers to buy the

through which it swings. Another factor involved in the period of motion is‚ the acceleration due to gravity (g)‚ which on the earth is 9.8 m/s2. It follows then that a long pendulum has a greater period than a shorter pendulum. Before coming to lab‚ you should visit the following web site: http://www.myphysicslab.com/pendulum1.html This simulation shows a simple pendulum operating under gravity. For small oscillations the pendulum is linear‚ but it is non-linear for larger oscillations. You can

location of the elements in the diffraction grating that produced them. Conversely‚ if we know the structure of the grating‚ we can deduce properties about the incident light‚ in particular its wavelength. This will be our task‚ in this first optics lab exercise. The analysis of diffraction patterns is used extensively in the sciences to provide information about the microscopic structure of molecules‚ atoms‚ and nuclei. In addition to various forms of light (gamma rays‚ x-rays‚ visible light‚ infra-red
