'Consider a 1 cm section of an earthworm with a diameter of 1.2 cm and a Young's modulus of elasticity of 3.813 kPa. The area of the circular muscles per centimeter length of the worm is 1.52 X lO"-3 crn'\"'2 and the maximum force generated per unit area of the muscles is 7 X lO"'6 dyn.-"'cm"'2. A. What is the force (N) generated by the circular muscles in this section of an earthworm? B. What is the pressure (Pa) developed inside the worm under maximum contraction of the circular muscles? C. What is the force (N) generated along the length of the earthworm when the circular muscles are under 111aximum contraction\"? D. By how much (percent) could a 1 cm section of an earthworm shorten if subjected to the pressure developed due to the contraction of the circular muscles
