Some fusion reactors use an induction process in which thermal neutrons collide with deuterium particles that are essentially twice as massive (consisting of one proton and one neutron). Consider a scenario in which a neutron is traveling at 1500 m/s when it collides elastically with a deuterium particle that is initially at rest. Find the magnitude of the neutron's recoil velocity (in m/s).

An air hockey puck of mass 0.42 kg is traveling at 3.5 m/s in a direction 30o North of East when it encounters another puck of mass 0.36 kg traveling 40o North of West at 2.8 m/s. The pucks were recently handled by my children so now they are sticky and collide inelastically. Find the magnitude of their velocity (in m/s) after the collision.

      In a process for which we have to use discrete probabilities to describe if an activity was carried out correctly or not, which of the following statements determines the defect probability of the entire process? The product of the individual defect probabilities The highest value of the individual defect probabilities The smallest value of the individual defect probabilities This really depends on the process, as it is possible that one process is more robust than the other

Beta has an opportunity to automate some of the billing process so that customers can use a direct account deduction. Moving to an automated billing process is voluntary for customers and Beta does not know what percentage will move. There are currently 100,000 customers. The cost of the billing process as currently constituted is $40,000 of annual fixed cost and $0.20 per bill. Automating the billing will result in a total of $50,000 of annual fixed cost, which is to...
