Brittany heats up the air in a capped syringe by placing it in a beaker of hot water. As air inside the syringe is heated, which of the following can be expected to occur.

A) the plunger will move further out of the syringe

B) the syringe will take in additional air and increase pressure

C) the pressure of the air inside the syringe will remain the same.

D) the plunger will move deeper into the syringe

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.
