1)Air temperature in a desert can reach56.0C (about133F).What is the speed of sound (in m/s) in air at that temperature? ______m/s

MY NOTES The two rigid objects shown in the figure below have the same mass, radius, and angular speed. If the same braking torque is applied to each, which takes longer to stop? more information is needed OA OB XA torque is applied to a long thin rod making it rotate with an angular acceleration of 3.65 rad/s about an axis through its center and perpendicular to its length (see figure (a) below). If the same torque is now applied to make the rod rotate about an axis about one end perpendicular to its length (see figure (b) below), determine the new angular acceleration of the rod. axis axis (a) ( b ) rad/s2 Supporting Materials Physical ConstantsImagine two circular plates; one is solid and the other has a hole cut out of the center. Both plates have the same radius, same thickness, and same mass. The same force F is applied tangential to the edge of each plate in such a way that the plates rotate about an axis passing through the center and perpendicular to the surface of the plates. Which one of the following statements is true regarding the angular acceleration? The solid plate will have the greater angular acceleration. Both plates will rotate with the same angular acceleration. The plate with the hole will have the greater angular acceleration. Which of the following statements helps to explain the question asked above? (Select all that apply.) Because both plates have the same mass, they will have the same moment of inertia. Angular acceleration is directly proportional to the moment of inertia. The plate with the hole has its mass distributed further out from the axis of rotation, which will increase its moment of inertia. Angular acceleration is inversely proportional to the moment of inertia. Both plates will be subjected to the same torque. X Consider the dependence of angular acceleration on torque and moment of inertia. Su
