In an effort to protect a rhino, volunteers are following its steps with air monitoring and ground cameras. the rhino starts on day 1 from ground camera a and walks for 1.5 km west along a straight line as seen from the air. the rhino then moves 0.7 km on a straight line in a direction of 15° east of north toward ground camera b. in this location the rhino may find water and food, therefore the animal stays for the night. on the second day, the rhino moves 2.5 km directly south as recorded from the air by the volunteers. in these two days of tracking how far and in which direction does the rhino travel from camera a?

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute

An electromagnet is a device in which moving electric chargers in a coil of wire create a magnet.whats one advantage of using electromagnetic in devices

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
