Technology is an improved route to an unimproved target. Technology is associated with innovation. It has definitely changed our lives for the better. Looking back in time‚ we realize that how much our lives have changed due to the fruits of technology.It has provided us with freedom and less consumption of time and resources. One the most effective pieces of technology is the mobile phone‚and nowadays being equivalent to a civilization. Due to technology changes‚ the dependency upon technology has

3. Recent technological developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands

ago today I was going to watching Kurt referee his very first high school basketball game. I was so excited and so proud of him. I had no clue three years ago how much reffing would become a part of our life. Reffing is life in our household. Honestly‚ reffing takes up about 9 months of our life. From November-March is basketball season. May-July are camps where he is away on the weekends. October is when he has all the clinics and scrimmages. Basically he is off April‚ August and September

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

interesting.The top part of her thumb has been cut of and a small hinge of skin is left out which fascinates her.She uses the simile ’A flap like hat’ for comparison and this creates a picture in the minds of the readers.It is just a small incident from our daily life‚ but Plath exaggerates and puts her imagination into it. She considers the thumb to be a pilgrim and says that the Indian’s axed the scalp and blood rolls on the carpet and she steps on it.The blood keeps on flowing even though she applies pressure

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

You throw the ball. You catch the ball‚" said a well-respected baseball manager by the name of Casey Stengel. Mr. Stengel was a baseball man‚ not a mathematician nor a physicist. Physics and mathematics can be applied to the game of baseball on every pitch‚ and on every swing of the bat. To understand the physics of the game‚ it is first necessary to look at the center of the game‚ the ball. Section 1.09 of the Official Baseball Rules states that the ball must weigh between 5 ounces and 5 ¼
