Imagine that a relaxed sarcomere is 2.4 μm long and that a contracted sarcomere is 2.1 μm long.

Imagine that a relaxed sarcomere is 2.4 μm long and that a contracted sarcomere is 2.1 μm long. Imagine further that the thin filaments are 1.0 μm long and the thick filaments are 1.5 μm long. To the nearest hundredths, what is the difference between the overlap (overlap of one thin filament with the thick filament) that occurs in a contracted sarcomere and the overlap that occurs in a relaxed sarcomere? It might help to draw a crude model of the sarcomere to help you visualize this problem.

Solutions

Expert Solution

  • The difference between the length of contracted and relaxed sarcomere is 0.4m.
  • Overlap value for contracted sarcomere is 0.75m. 0.55m is the overlapping value in the case of relaxed sarcomere.
  • The difference between these overlap gives the value of 0.20m.

3. Testing for equal proportions Imagine that you are contracted by a local news provider to study consumer demographics in relation to three different types of news media: print (newspaper), Internet, and television. In prior market research, the company has classified each of its customers as receiving news content primarily from only one of these three sources, and as either urban or rural residents. In order to help design effective marketing strategies, you are asked to perform a test for...

A 2.4 kg block hangs from the bottom of a 2.0 kg, 1.6 m long rod. The block and the rod form a pendulum that swings out on a frictionless pivot at the top end of the rod. A 10 g bullet is fired horizontally into the block, where it sticks, causing the pendulum to swing out to an angle of 45 degrees. You can treat the wood black as a point mass. What is the moment of inertia of...

A 283 g air track glider moving at 0.69 m/s on a 2.4 m long air track collides elastically with a 467 g glider at rest in the middle of the horizontal track. The end of the track over which the struck glider moves is not frictionless, and the glider moves with a coefficient of kinetic friciton = 0.02 with respect to the track. Will the glider reach the end of the track? Neglect the length of the gliders.
