Jim is lifting weights. Holding a 20lb weight down by his side, he bends his arm at the elbow, contracting his bicep, and holds the position until he reaches muscle fatigue. Briefly describe how the Henneman Size Principle relates to this example. List the steps of muscle fiber recruitment necessary for the initial lift and subsequent fatigue. Include a short summary of the muscle fiber types, and the properties that contribute to the speed of contraction, recruitment pattern and metabolic...

(a) Light from distant objects, such as stars, are imaged by a single lens. Assuming the focal length of the lens is 10 cm and the aperture size is 2 cm, what is the minimum resolvable angle? Write every step. (b) The same lens is used for imaging an amplitude grating. What is the minimum grating spacing that will yield any intensity variation(s) on the image plane using (i) coherent and (ii) incoherent illumination? Be very specific in your answer...
