This is a kind of electroscope student made in science class to study charges. Student Procedure: ~Tear off two pieces of tape, each 4 inches (10 cm) long. ~Press each piece firmly on the work table leaving one end of each tape piece sticking up as a handle. ~Quickly pull the tapes from the table and stick one piece on the arm of a straw in one film canister, and the other piece on the arm of a straw in the other film canister. ~Move the canisters so the two pieces of tape are face to face, about 6 inches apart. ~Slowly move the canisters closer together. This is a photograph of what occurred as the canisters were moved toward each other. Which of these conclusions is NOT accurate. A) The pieces of tape have like charges. B) The charged pieces of tape exert a force on each other. C) Because the pieces of tape have like charges they will repel each other. D) The closer the canisters get, the less likely the pieces of tape will repel.

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.
