To be able to add and subtract vectors using geometric and vector addition. A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d_1 = 23.5 mat theta_1 = 25.5 degree from the tree then turned and traveled d_2 = 12.0 m at theta_2 = 137 degree. Meanwhile, the sister traveled d_3 = 18.5 m at an angle of theta_3 = -110 degree from the tree. The angles are given with respect to east with counterclockwise being defined as positive Using the parallelogram law to add these vectors geometrically, determine the displacement of the boy relative to the tree. Express your answers, separated by a comma, to three significant figures. Enter the angle measured counterclockwise from the positive x axis. Displacement from the boy to the girl Using the method of vector addition by components, determine the displacement from the boy to the girl. Express your answers, separated by a comma, to three significant figures. Enter the angle measured counterclockwise from the positive x axis.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
