What Are the Three Branches of US Government

The United States has three branches of government: the executive, the legislative and the judicial. Each of these branches has a distinct and essential role in the function of the government, and they were established in Articles 1 (legislative), 2 (executive) and 3 (judicial) of the U.S. Constitution. The Executive Branch The executive branch consists of the president, vice president and 15 Cabinet-level departments such as State, Defense, Interior, Transportation, and Education. The primary power of the executive branch rests with the president, who chooses his vice president, and his Cabinet members who head the respective departments. A crucial function of the executive branch is to ensure that laws are carried out and enforced to facilitate such day-to-day responsibilities of the federal government as collecting taxes, safeguarding the homeland and representing the United States political and economic interests around the world. The President The president leads American people and the federal government. He or she also acts as the head of state, and as Commander in Chief of the United States Armed Forces. The president is responsible for formulating the nation’s foreign and domestic policy and for developing the annual federal operating budget with the approval of Congress. The president is freely elected by the people through the Electoral College system. The president serves a four-year term in office and can be elected no more than twice. The Vice President The vice president assists and advises the president, and must be ready at all times to assume the presidency in the event of the president’s death, resignation, or temporary incapacitation. The Vice President also serves as the President of the United States Senate, where he or she casts the deciding vote in the case of a tie. The vice president is elected along with the president as a â€Å"running mate† and can be elected and serve an unlimited number of four-year under multiple presidents. The Cabinet The President’s Cabinet serves as advisors to the president. They include the vice president, the heads of the 15 executive departments, and other high-ranking government officials. Each Cabinet member also holds a spot in the presidential line of succession. After the Vice President, Speaker of the House, and President pro tempore of the Senate, the line of succession continues with the Cabinet offices in the order in which the departments were created. With the exception of the vice president, Cabinet members are nominated by the president and must be approved by a simple majority of the Senate. The Legislative Branch The legislative branch consists of the Senate and the House of Representatives, collectively known as the Congress. There are 100 senators; each state has two. Each state has a different number of representatives, with the number determined by the states population, through a process known as apportionment. At present, there are 435 members of the House. The legislative branch, as a whole, is charged with passing the nations laws and allocating funds for the running of the federal government and providing assistance to the 50 U.S. states. The Judicial Branch The judicial branch consists of the United States Supreme Court and lower federal courts. Under the Supreme Courts constitutional jurisdiction, its primary function is to hear cases that challenge the constitutionality of legislation or require interpretation of that legislation. The U.S. Supreme Court has nine Justices, who are nominated by the president and must be confirmed by a simple majority vote of the Senate. Once appointed, Supreme Court justices serve until they retire, resign, die or are impeached. The lower federal courts also decide cases dealing with the constitutionality of laws, as well as cases involving the laws and treaties of the U.S. ambassadors and public ministers, disputes between two or more states, admiralty law, also known as maritime law, and bankruptcy cases. Decisions of the lower federal courts can be and often are appealed to the U.S. Supreme Court. Checks and Balances Why are there three separate and distinct branches of government, each with a different function? The framers of the Constitution did not wish to return to the totalitarian system of governance imposed on colonial America by the British government. To ensure that no single person or entity had a monopoly on power, the Founding Fathers designed and instituted a system of checks and balances. The presidents power is checked by the Congress, which can refuse to confirm his appointees, for example, and has the power to impeach or remove, a president. Congress may pass laws, but the president has the power to veto them (Congress, in turn, may override a veto). And the Supreme Court can rule on the constitutionality of a law, but Congress, with approval from two-thirds of the states, may amend the Constitution.

International Business Machines ( Ibm ) Case Study

International Business Machines (IBM) Case Study In 1990, IBM was the second most profitable company in the world. It recorded a net income of $6 billion on revenues of $69 billion. Even though IBM recorded such high revenues and the senior executives complacent because things seemed to be better there were uprising problems in the company (Applegate, Austin Collins, 2009). There were serious structural problems within the company. These structural problems caused the company’s earnings to drop. In between 1991- 1993 the earnings dropped continually. Some of the problems the company faced came from its blindness to hubris (Applegate, Austin Collins, 2009). The company also barely communicated with its customers. The company also got distracted by internal turf wars than market place battles. The PC group considered the rest of IBM outdated and wanted nothing to do with them. Over time the business matured and the PC group could not leverage the sales and global services strengths of the company (Applegate, Austin Collins, 2009). Executives ignored the growing problems in the organization; instead they focused on the deep levels of hierarchy. They also ignored the upcoming problems because they heavily relied on the large numbers of corporate staff. The leaders had large staffs and little direct involvement in writing their own reports. It displayed poor performance in the structure of the company.

Impact of Jet free essay sample

The purpose of the impact of jet experiment is to design a system to determine the force generated by the impact of jet on a variety of target vanes. A formula is given to calculate the reaction force at the different vanes caused by the jet. At the end of the experiment, the data collected and results calculated will then be compared to theoretical values which are given. Students are expected to be able to come to a conclusion regarding the relationship between the reaction force produced at the target vanes and the angle where the shape of the vanes curve. 1. 1 INTRODUCTION There are many ways to produce mechanical work from fluid under pressure. One of the famous ways is to use the pressure to accelerate the fluid to a high velocity in a jet. Over the years, engineers have found many ways to utilize the force that can be produced by a jet of fluid on a surface diverting the flow. This helps us to understand how forces can affect the change of momentum flow in the jet. The theoretical jet force can be calculated from the principle of linear momentum. The density of water is 1kg/L. The results obtained are to be compared with the theoretical values. To produce mechanical work from fluid under pressure, we use the pressure to accelerate the fluid to a high velocity in a jet. The application of this principle can be seen surrounding us. For example, water turbines are used to generate power in our country. Another example is that the kinetic energy stored in a jet is used by the firemen to deliver water above the level in the nozzle to extinguish fires in tall buildings. And also, the pelton on wheel is used to make flour. 3. 0 APPARATUS i. HM150 impact of jet a) Loading weights b) Lever mechanism c) Deflector d) Nozzle e) Perspex vessel f) Drain connection g) Base plate. Inlet connection ii. Various deflector Plate Hemisphere Slope Cone iii. A set of weights iv. Stop watch 3. 1 PROCEDURES 1) A quick inspection is performed to ensure that the units is in proper operating condition. 2) A hose connection made and the unit is connected to the nearest power supply. 3) The discharge pipe is opened. 4) One of the deflectors (plate, hemisphere, slope or cone) is assembled. The three screws (3) on the cover (4) is loosen. The cover is removed together with the lever mechanism. 5) An appropriate deflector is fitted. The lock nut (2) on the rod is tightened. The cover is screwed back onto the vessel. Adjusting screw (5) is used to set pointer to zero (7). Any loading weights are not placed on measurement system when doing so. 7) The desired loading weight :0. 2N, 0. 3N, 1N, 2N, and 5N is applied. 8) The main clock is closed. 9) The pump is switched and the main cock is opened carefully until pointer is on zero again. 10) The drain cock is closed and the volumetric flow rate is determined by using stopwatch to establish time required for raising the level in the volumetric tank from 20 to 30 liters. 11) The pump is switched off and the drain is opened. In this experiment, hemisphere deflector has the lowest flow rate among the deflectors used. This indicates that hemisphere deflectors are the most efficient to be used in water turbines. The calculated forces for each deflector are different from the measured forces. The comparison between calculated force and measured force for each deflectors is stated in the table below : Example value :1 N Calculated force, Fth in N Measured force, F in N Plate 0. 67 1. 0 Hemisphere 0. 92 1. 0 Slope 2. 77 1. 0 Cone 1. 19 1. 0 To calculate the percentage of error: Percentage of error = Theoretically, the calculated force is supposed to be the same as the measured force. The percentage of error in this experiment ranged from 3% to 177%. The difference between the calculated force and measured force is due to some errors made throughout the experiment. For example, when setting the pointer, due to parallax error, the pointer may not be set to zero precisely. Next, when adjusting the main cock, error might be made. The main cock may not properly open thus causing the pointer not exactly at zero. Another possibility is that when measuring the water level raise from 10 L to 20 L, parallax error might occured. To improve the accuracy of this experiment,we may repeat the steps to get consistent values. In order to improve the errors, when setting the pointer, make sure the eye level is at the same level with the pointer to ensure it is set to zero accurately. Next, make sure the main cock is properly open by double checking it. Reading on volumetric tank should be on the water meniscus to avoid parallax error. We also must make sure the control valve is completely close before the pump is switched on in order to avoid intrusion of air into the pump. Entrapped air may reduce the exerted force of the jet. Conclusion In conclusion, the momentum equation is verified experimentally through this experiment. The calculated force is supposed to be the same as measured force. But in this experiment, the difference between the calculated force and the measured force may due to some errors made during the experiment. In this experiment, the hemisphere deflector has the lowest flow rate and takes longer time for the volumetric tank to rise from 10 L to 20 L compared to the other deflectors. Therefore hemisphere deflector is the most efficient to be used in water turbine.
