can i please get help on this type of problem please. I would really apprecite it. i am having trouble with parts d-g. A muscle cell (fiber) in a biceps is 20cm long and contains 1500 myofibrils arranged parallel to each other. Each myofibril is made up of many sarcomeres, organized in series, that behave as springs. A relaxed sarcomere is 2μm long. When contracted, the cell shortens to half its length and develops a force of 30mN. Each of those structures, the cell, myofibril and sarcomere, can be modeled as a spring. a) Calculate the spring constant of a muscle cell. b) The 1500 myofibrils in the muscle cell are arranged in parallel. Calculate the spring constant of a single myofibril. c) The myofibrils are composed of sarcomeres that are arranged in series. Calculate the number of sarcomeres in each myofibril then calculate the spring constant of a single sarcomere. d) When we shiver in the cold, our muscles oscillate at a frequency of 10Hz and with an amplitude of 2cm.

In our discussion class, we found the expression of the angle 0 when the current loop pictured below reaches mechanical equilibrium. Call that angle 0. Now, suppose the loop has been turned to a new angle, 0 = 00 + 8, slightly away from equilibrium (so |8| << 0o), and let go. A simple harmonic oscillation of the loop ensues. Find the expression of the frequency f of the oscillation, and its numerical value if B = 800 mT, Io = 4.0 x 10-3 kg · m² (Moment of inertia about the axis through O), k = 200 N/m , b = 28 cm, and I = 1.6 A. %3D B В k k I Figure TP28.1 527

Neglecting the resistance of the medium. Find the displacement in ft after 8 seconds of an 18lb object attached to the end of a spring. It comes to rest at its equillibrium position, thereby stretching to 12 inches. The object is then pulled down 0.5 ft below its equillibrium position and released at t=0 with an initial velocity of 1ft/s directed downward.

This problem explores how a current-carrying wire can be accelerated by a magnetic field. You will use the ideas of magnetic flux and the EMF due to change of flux through a loop. Note that there is an involved follow-up part that will be shown once you have found the answer to Part B. Part C What is the acceleration a, (t) of the rod? Take m to be the mass of the rod. Figure 1 of 1 Express your answer as a function of V, B, the velocity of the rod v, (t), L, R, and the mass of the rod m. ? a,(t) = rod
