31. II Your forehead can withstand a force of about 6.0 kN before BIO fracturing, while your cheekbone can withstand only about 3 kN. Suppose a 140 g baseball traveling at 30 m/s strikes your head and stops in 1.5 ms. a. What is the magnitude of the force that stops the baseball? b. What force does the baseball exert on your head? Explain. c. Are you in danger of a fracture if the ball hits you in the fore-...
what is a problem with using a spin lock instead of a mutex? a. small critical sections that are executed repeatedly by the same thread, can cause problems in the CPU itself due to centrifugal force b. if the critical section is large, CPU time can be wasted when two threads try to execute the critical section at the same time c. spin locks are always better than mutexes if you don’t need condition variables d. spin locks are not...
