1. i) • Antenna radiation pattern or antenna pattern is defined as “a mathematical function or a graphical representation of the radiation properties of the antenna as a function of space coordinates.” • The radiation pattern is determined in the far-field region and is represented as a function of the directional coordinates. • Radiation properties include power flux density‚ radiation intensity‚ field strength‚ directivity phase or polarization [pic]

A wide range of punctuation is used‚ including speech marks‚ apostrophes‚ brackets and ellipses‚ to create clarity and sometimes for effect (AF6). There are some effective vocabulary choices (’murky’‚ ’rasped’) (AF7) which add to the impact of the narrative. Although children were given a starting point for their narratives‚ and some support

* Water has a higher relative density (800 times higher than air) and is a viscous medium to move through. * The body of a fish is of a streamlined shape to move quickly in water. * The streamlined shape of a fish: * a) is long ellipse tapering to a point (shaped like a torpedo) in the direction of the flow of water. * b) reduces the drag (a drag is water resistance caused by friction between moving water and the body of the fish). * The general adaptive features

includes the Earth and all the other objects that orbit the Sun. Historically‚ galaxies have been categorized according to their apparent shape (usually referred to as their visual morphology). A common form is the elliptical galaxy‚ which has an ellipse-shaped light profile. Spiral galaxies are disk-shaped assemblages with curving‚ dusty arms. Galaxies with irregular or unusual shapes are known as peculiar galaxies‚ and typically result from disruption by the gravitational pull of neighboring galaxies

Scientific Revolution: The scientific revolution refers to the period of historical changes in thought & belief‚ as well as proposed universal laws. This period brought ideas not only on the motion of the spheres‚ but on the influence of God on daily life and nature theorized by philosophers such as Nicholas Copernicus and Isaac Newton. The Author‚ Its Work: Nicolaus Copernicus‚ On the Revolutions; the Heliocentric Model. Nicolaus Copernicus proposed the idea that the sun was stationary object centered
