This chart lists four examples of two objects that are in contact. A 3-column table with 4 rows. The first column has entries Example 1, Example 2, Example 3, Example 4. The second column labeled Object 1 has entries fire, a metal at 80 degrees Celsius, the cool ocean, a tool with a lot of thermal energy. The third column labeled Object 2 has entries air, a metal at 12 degrees Celsius, the warm air, a material with little thermal energy. Which statement accurately describes the flow of heat in each example? Heat will flow from Object 1 to Object 2 in examples 2 and 4, and heat will flow from Object 2 to Object 1 in examples 1 and 3. Heat will flow from Object 1 to Object 2 in examples 1 and 3, and heat will flow from Object 2 to Object 1 in examples 2 and 4. Heat will flow from Object 1 to Object 2 in Example 3, and heat will flow from Object 2 to Object 1 in examples 1, 2, and 4.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
