A certain spring has a force constant k. (a) If two such identical springs are connected in parallel to each other as shown in part (a) of Figure 6-36, does the resulting double spring have an effective force constant that is greater than, less than, or equal to k? Explain. (b) If two of the original springs are connected as shown in part (b) of Figure 6-36, does the resulting double spring have an effective force constant that is greater than less than or equal to k? Explain.

A relaxed sarcomere is 5 μm long. When contracted, the cell shortens to half its length and develops a force of 33 mN. Each of those structures, the cell, myofibril, and sarcomere, can be modeled as a spring.When we shiver in the cold, our muscles oscillate at a frequency of 13 Hz and with an amplitude of 5 cm. Assume a muscle is a simple harmonic oscillatory and calculate the mass of the load on that oscillator.

- For a system of two particles we often let the potential energy for the force between the particles approach zero as the separation of the particles approaches infinity. If this choice is made, explain why the potential energy at noninfinite separation is positive if the particles repel one another and negative if they attract.arrow_forward(a) The engineer designing the release mechanism shown in the figure wants the normal force exerted at C to be 120 N.
