| As the initially empty urinary bladder fills with urine and expands, its internal pressure increases by 3300 Pa, which trig- gers the micturition reflex (the feeling of the need to urinate). The draw- ing shows a horizontal, square section of the bladder wall with an edge length of 0.010 m. Because the bladder is stretched, four tension forces of equal magnitude T act on the square section, one at each edge, and each force is directed at an angle 0 below the horizontal. What is the magni- tude T of the tension force acting on one edge of the section when the internal bladder pressure is 3300 Pa and each of the four tension forces is *19. directed 5.0° below the horizontal?
