First one to answer gets
the diagram shows parts of a rip current.
which part of the rip current is most dangerous to a swimmer, and why?

a. the feeder is the most dangerous part of the rip current because the water’s speed increases and swimmers can be swept against the shore.
b. the neck is the most dangerous part of the rip current because the water’s speed increases and swimmers can be pushed farther into the ocean.
c. the head is the most dangerous part of the rip current because the water’s speed increases and swimmers can be pulled down to the ocean floor.
d. the breaker is the most dangerous part of the rip current because the water’s speed increases and swimmers can be swept toward a sandbar.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
