This turbulence is caused by inertia Questions 1) The observations of the behavior of water inside the container (turbulence) conform to Newton’s law of inertia. While moving with the container, water inside the glass also moves at the same speed. When an abrupt stop or left or right hand turn is made, the speed of the water inside the container is suddenly changed and water resists this change of motion (Nardo, Don, and Ashlee 16). 2) While the container is accelerated towards the left, water moves in the same direction of acceleration and resists the forces that compel it to stop. 3) Another similar example to this experiment is when one is driving a car. The body of the driver will be moving at a speed that is equal to the speed of the car. When the driver makes a sudden stop, his body will continue moving at the speed and he will resist the sudden change of speed. Therefore, the driver’s body will experience inertia, which is the reluctance to sudden change of motion or speed The washers with the larger mass and weight pull the washers on the other side of the pulley. The lighter washers move up the pulley while the heavier washers move down the pulley.

Both ends of the string are attached to two chairs that are separated ten meters away from each other. The balloon is inflated with air and placed next to one end of a chair. Observation: On releasing the balloon, it moves instantaneously in the opposite direction while it pools the straw towards the other end of the chair. This observation can be used to explain Newton’s third law of motion that states that for every action there is an equal and opposite reaction. 1. Explanation of observation: The air that was filled inside the balloon was under pressure. When the balloon is released, the air shoots out of the balloon in an opposite direction. The force exerted by the air that moves out of the balloon has another equal and opposite force (the balloon) that causes the balloon to move in the opposite d ...Download file to see next pagesRead More

RealClimate.org. http://www.realclimate.org/index.php/archives/2005/01/is-climate-modelling-science/) According to the new scientist magazine, climatic models are true. They all point to the argument that the world is warming. And this is being caused by human activities. If the model predictions are neglected, more sever consequences will be experienced. The article points out that serious scrutiny needs to be done to help in formulating better models instead of discrediting them. (Pearce, (2007, May 16) According to the Intergovernmental Panel on Climate Change (IPCC Working Group 1, 2008); the models can be used to predict accurately climatic changes....

This kind of movement serves to waste time that could effectively be used in the production of additional products (Qi, Boyer, & Zhao 2009, p.698). This is one reason why the company can only meet a limited number of orders in a single week. The reorganization of the operations plant can present the PD aquarium company with an opportunity to register a higher level of production in a remarkably shorter period (Yinan, Xiande, & Chwen 2011, p.374).

When Iridium was developing there was space for room for product development since there were minimal developments in the phone industry. In the early and mid-1990s, cell phone companies lacked the required infrastructure to offer products for their customers. Due to rapid expansion of the industry at the time many companies lacked the capacity to offer services to customers. Users were unable to make calls comfortably. There were many difficulties facing the cell phone industry at the time. Due to such limitations in cell phone technologies, the satellite phone was the best...
