Julie sits on a swing. Her free-body diagram is shown. A free body diagram with 2 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 265 N. The second vector is pointing upward, labeled F Subscript N Baseline = 265 N. The vectors are the same length.

The net force on Julie is N

What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same? o a. resistance is directly related to length. ob. resistance is directly related to the square of the length. c. resistance is inversely related to the length. d. resistance is inversely related to the square of the length. reset next

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.

The ability to make things happen is also called a. heat b. force c. matter d. energy
