Alex is asked to move two boxes of books in contact with each other and resting on a frictionless floor. He decides to move them at the same time by pushing on box A with a horizontal pushing force \vec{F}_p = (+8.20\hat{i})N. Here A has a mass $m_A = 15.1$ kg and B has a mass $m_B = 7.00$ kg. The contact force between the two boxes is \vec{F}_C and \vec{N} denotes the normal force. (a) What is the magnitude of the acceleration of the two boxes? m/s² (b) What is the magnitude of the force \vec{F}_C exerted on $m_B$ by $m_A$? N (c) If Alex were to push with the same magnitude of force $|\vec{F}_p|$ from the other side on the 7.00 kg box, what would be the magnitude of the force \vec{F}_C exerted on $m_A$ by $m_B$? (Assume the force \vec{F}_C on the left side is no longer present.)
Dr. Silas conducts a study to determine whether her new energy drink helps children perform better on spelling tests. She randomly assigns children to one of two groups: Group 1 receives her energy drink and Group 2 receives water. She then gives both groups a spelling test and compares the results. The __________ is the type of drink the children receive.

If one says their ethics identity is to follow the Moral Minimum (as it is commonly called), it is fair to say that that person is not really living an ethical life in a meaningful way. True False
Part C - Carbohydrate, Protein, and Fat Digestive Enzymes An important objective in this chapter is to identify the major enzymes in the digestion of carbohydrates, proteins, and fats as well as the organs that secrete them. This activity requires you to match the enzyme with the secreting organ(s). Drag the appropriate items into their respective bins. ?

A vinyl monomer M (Mw=156) is polymerized via free-radical polymerization using a peroxide initiator P. Termination of growing polymer chains is by disproportionation. The peroxide initiator has a half-life of 1 hour at 90 °C and an activation energy of 30 kcal/mol. In a run at 60 °C the initial charge to the reactor is 1.00 × 10?³ mol of P and 2.00 mol of M is in total reactor solution mixture volume of 2,500 mL. The reaction is stopped after 35 minutes at which time 12.5 g of polymer has been formed. What is the expected instantaneous number-average molecular weight of the polymer formed when the reaction was stopped?
