Core Assumptions and Statements The theory suggests that the mass media could influence a very large group of people directly and uniformly by ‘shooting’ or ‘injecting’ them with appropriate messages designed to trigger a desired response.

direct paths to radar inside the forest. The human is modeled using PEC ellipsoids‚ created based on the Boulic model as described in Section 2. The forest is modeled using identical trunks of 3 meters height and 11 cm radius which are distributed uniformly inside the 40£40m2 region. PEC is assumed for the trunk material properties as well as the ground. A trunk density of 3.8% (#/m2) is assumed‚ which amounts to 35 trunks within the half power beamwidth of the antenna‚ with average closest neighbor

m/s/s/)(5s)2 = 100m – 50m = 50 m 5. A car whose initial speed is 30 m/s slows uniformly to 10 m/s in 5 seconds. a) Determine the acceleration of the car. v = vi+at = 10m/s = 30 m/s + a(5s) => 10-30 = 5a => = (-10m/s)/(5s) = -4 m/s/s 6. A dog runs down his driveway with an initial speed of 5 m/s for 8 s‚ then uniformly increases his speed to 10 m/s in 5 s. a) What was his acceleration during the 2nd part of the motion? b) How long is the driveway? v = vi+at = 10m/s = 5 m/s + a(5s)

He wrote couple of treatise about mathematics and astronomy. Some of them were lost. His most famous works Aryabhatiya completed in 499 CE and the Arya-Siddhanta. Aryabhatiya consists of 108 verses‚ in which Aryabhata wrote about the mathematics and astronomy at the age of 23

frictionless motion. A known mass is attached to an air-cart on an air-track apparatus. Attached by string‚ the air-cart is pulled by the known mass when hung over a pulley. A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment‚ enabling the system of masses to move without an applied force or a frictional force. This experiment will measure the motion of an
