Based on this passage, what is campylobacter?

physicians rely on drugs like ciprofloxacin and azithromycin for treating patients with severe disease…. campylobacter is estimated to cause approximately 1.3 million infections, 13,000 hospitalizations, and 120 deaths each year in the united states. the cdc is seeing resistance to ciprofloxacin in almost 25 percent of campylobacter tested and resistance to azithromycin in about 2 percent.

1.) an antibiotic

2.) a drug-resistant bacteria

3.) a drug that targets specific types of bacteria

4.) a test to identify drug-resistant bacteria

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v 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. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
