Physics assignment - Essay Example The air opposing the spinning ball causes different air friction at different sides of the ball depending upon the direction of rotation. Due to differing air action on two sides the ball curves towards one side, if a ball is rotating anti-clockwise, the air on its right side causes more impedance because of the ball surface moving against the wind, than on its left side. This is moving in the direction of the wind hence causing the ball to curve towards left. Ball A will travel longer in the air. It happens because the smoothness of the ball causes the air to curve around its surface without creating a lot of resistance during its motion, thus the air drag is low, where as ball B will travel shorter in the air. This is due to the rough surface of the ball that will act as small pockets to the air that is curving around the ball, hence causing air friction on it. This will reduce the energy of ball B greatly. The ball B hence, will travel a shorter distance compared to the Ball A. The S waves travel perpendicular to the direction of the vibration, where as the P waves travel in a direction parallel to the oscillations of the particles. The P waves travel with twice the speed of S waves. The P waves travel in forms of compression and rarefaction zones whereas the S waves travel in form of ripples. The P waves starts forming much earlier than the S

Census Koreans in LA - Research Proposal Example This population continues to enlarge since the historic immigration into Bunker Hill two decades in the wake of the 20th century (Theme 98). Bunker Hill is in present-day Los Angeles. Then, this region was designated for non-whites and ethnic minorities were allowed to reside during the first two decades of the century. Earliest Korean immigrants into the US had domestic and casual jobs, which involved hard labor in manufacturing and other operating plants. The Korean community migrated into geographical territory covering the region from Vermont Streets and Normandie. This area is the present-day Korea Town, California. By the 1950s, Los Angeles received the second wave of ethnic Korean immigrants from the Korean War. This population combined with the descendants of the first-wave immigration influx of the 1900s and the demographics began to soar amid rising birth rates and continued intermarriage interaction with other races. Most of the Korean population worked as truck drivers, waiters, and domestic workers for most of the 20th century (Gives 87). Present demographic statistics indicates that Korean Americans living in California account for 18.5 % of the entire ethnic Korean demographic in the United States (Min 67). Los Angeles County is home to over half a million ethnic Korean – demographic includes intermarried and those of interracial
