Arelaxed biceps muscle requires a force of 25.0 n for an elongation of 3.0 cm; the same muscle under maximum tension requires a force of 500 n for the same elongation. the muscle is assumed to be a uniform cylinder with length 0.200 m and cross-sectional area 50.0cm2.

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

What is the magnitude of the resultant vector round your answer to the nearest tenth
