1The curl vector and rotation of a solid body. In this part of the project we study a connection between the curl vector and rotations. Let B be a rigid body rotating about the z axis. The rotation can be described by the vector where a, is the angular speed of B, that is, the tangential speed of any point P in B divided by the distance d from the axis of rotation. Letアー〈z, y, z) be the position vector of P (a) By considering the angle θ in the figure, show that the velocity field of B is given by = w ×ア. [In the figure "bold face" notation is used for vectors.] (b) Show that t--wy→ + wz7. (c) Show that curl T-2 0

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
