Correct. As shown in the Video surface tension forces can be strong enough to allow a double-edge steel razor blade to \"float\" on water, but a single-edge blade will sink. Assume that the surface tension forces act at an angle relative to the water surface as shown in the figure below. (a) The mass of the double-edge blade is $0.72 \times 10^{-3}$ kg, and the total length of its sides is 180 mm. Determine the value of $\theta$ required to maintain equilibrium between the blade weight and the resultant surface tension force. (b) The mass of the single-edge blade is $2.30 \times 10^{-3}$ kg, and the total length of its sides is 170 mm. Explain why this blade sinks. Support your answer with the necessary calculations. To begin this problem, we need:

Part II (20 points each): Choose 2 of the following 3 questions to answer, clearly marking which ones you want counted. In each case, answer the question as given. Be sure to clearly label any graphs and write your answers as completely as possible. 1. Consider a small economy with only two individuals—Sarah and Allen. The community is considering building a park in the center of town. The park is nonexcludable and nonrival in consumption. The figure below illustrates the marginal benefits the two individuals receive from a park as a function of park size (acres). P 10- 0 50- MBs MBA 20 0 0 5 10 MC q (a) What does nonexcludable and nonrival in consumption mean in this context? (b) If the marginal cost of the park is $20 per acre, identify how many acres would be purchased allowing for free riding. What is each individual's marginal willingness-to-pay (MWTP) for parks at this size park? (c) How many acres would be optimal for the community and what would be the total net benefit (TNB) to the community from the park (Note: You can either compute the TNB mathematically or illustrate it using the graph.) What is each individual's marginal willingness-to-pay (MWTP) for parks at this size park? (d) How would your answers in parts (b) and (c) change if a new person were to move into the community, say with the same preferences as Allen?
