An engineering team has come to the stage in the engineering design process in which it is iterating to improve the solution . What is one thing they might be doing ? A. Identifying the limits on how the prototype can be used to solve the engineering problem

B. Identifying different sets of criteria and constrains to use for each possible solution

C. Choosing one solution to model out of many possible solutions the team has identified

D. Making improvements to the original prototype in order to perform more tests

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?
