The mechanism shown in the figure is used to raise a crate of supplies from a ship’s hold. The crate has total mass 48 . A rope is wrapped around a wooden cylinder that turns on a metal axle. The cylinder has radius 0.30 and a moment of inertia = 2.5 about the axle. The crate is suspended from the free end of the rope. One end of the axle pivots on frictionless bearings; a crank handle is attached to the other end. When the crank is turned, the end of the handle rotates about the axle in a vertical circle of radius 0.12 , the cylinder turns, and the crate is raised.

A constant horizontal force Fa pushes a 1.50 kg FedEx package across a frictionless floor on which an xy coordinate system has been drawn. Figure 5-37 gives the package’s x and y velocity components versus time t. (The vx axis is marked in increments of 1 m/s and the vy axis is marked in increments of 2 m/s.) What are the (a) magnitude and (b) direction of a (angle clockwise from +x axis)?

Protein intakes two to three times the RDA are not uncommon in the United States.

Protein intakes two to three times the RDA are not uncommon in the United States. Using the food values found on the Evolve website that accompanies your textbook, calculate the energy value and the number of grams of protein in a fast-food meal that includes one double-patty cheeseburger, a large serving of French fries, and a 12-oz milkshake. Compare the total grams of protein and the total kcalories with the protein and energy DRIs for a 16-year-old boy. What proportion of his daily protein and energy needs are provided in this meal?

4. In addition to hydrogen, methane also has been studied for use in PEM fuel cells. Balance the given oxidation and reduction half reactions, and write the overall equation for a methane-based fuel cell. (4 points)

             a. Oxidation half reaction:          ___ CH4(g) + ___ H2O(l) → ___CO2(g) + ___H+(aq) + ___e—

             b. Reduction half-reaction:       ___O2(g) + ___H+(aq) + ___e- → ___H2O

5. Hydrogen and methane both can react with oxygen in a fuel cell. They can also be burned directly. Which has greater heat content when burned, 1.00g of H2 or 1.00g of CH4? (Hint: Write the balanced chemical equation for each reaction and use the bond energies in Table 5.1 to help answer this.) (6 points)

6. After reading this chapter, which battery source do you think is the most efficient and most effective for your daily activities? Explain. (3 points)
