Use this panoramic image to identify these 11 numbered structures. 12. 14.  17. 19. 21. 22. 23. 24. 25. 26. 27.

A tooth with pulpal necrosis typically shows which radiographic feature?

Internal resorption appears radiographically as:

Nelly Korda accelerates the club from the top of the backwing until impact with the ball with an acceleration of 30 rad/s2 for a period of 0.5s. Her radius of rotation is 1.1m. If you want to evaluate her performance by calculating the angular velocity of her club at impact, which equation would you use?

What are the units for angular momentum (H)? 

A 50k diver in a full layout position, with a total body radius of gyration with respect to their transverse principal axis equal to 0.45m, leaves a springboard with an agular velocity of 6rad/s. She tucks her knees into a radius of gyration of 0.25m. To calculate her angular momentum at takeoff, what formula would you use? 

You can increase your stability by: (Choose all that apply)

Which of the following represent appropriate units of measurement for tangential acceleration?

True or False. As compared to the trunk, hip, and ankle, the knee joint goes through the greatest range of angular motion during a typical gait cycle.
