The anterior cruciate ligament in a woman's knee is 2.4 cm long and has a cross-sectional area of 0.53 cm2. Assume that the Young's modulus of the ligament is 1.0×108 N/m2. If a force of 2300 N is applied longitudinally, by how much ΔL will the ligament stretch?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
